This manual is divided into two main sections: airplanes and helicopters. You need only refer to the section that pertains to the type of model you are programming e.g., if you are programming your XF662 for helicopters, follow the instructions in the helicopter section. Blank data sheets are included at the end of both sections. Once you have input all the necessary data into your transmitter for a particular model, we strongly recommend that you immediately write that information down on a copy of the data sheet provided. This is to insure that, in the rare case of a memory failure, you will not lose your data. CHAPTER 2: FEATURES 2.1 TRANSMITTER FEATURES 6-model memory Easy-to-read LCD screen Airplane and Helicopter Mode 6-model name entry Dual rates on aileron and elevator Dual rates can be combined on one switch Exponential rate on aileron and elevator Trainer system compatible with most JR radios Easy-access programming buttons Computer designed ergonomically styled case Adjustable stick length Throttle trim only affects idle position Two speed scrolling: press and hold the appropriate button to scroll quickly or press and release to scroll in steps FM/PCM selectable Fail-safe/fail-safe memory (PCM only) Digital trims for precise adjustment 2.2 RECEIVER FEATURES R700 Slimline Receiver The R700s extremely compact slimline design allows it to fit easily in limited spaces. An independent laboratory ranked the R700 Receiver with JRs patented ABC&W circuitry as one of the best receivers ever tested in terms of 3IM, 2IM, signal-to-noise ratio, adjacent channel rejection, and on-channel capture point. The R700 is compatible with all JR FM transmitting radios. Airplane Mode Aileron to rudder mixing Elevator to flap mixing Flap to elevator mixing Flaperons mixing Delta wing mixing Aileron differential V-tail mixing Three programmable mixes Mixing differential Helicopter Mode Two 3-point throttle curves Two 3-point pitch curves (three when throttle hold is activated) Flight mode switch can combine throttle curve, pitch curve, dual rates, and gyro sensitivity Throttle hold Revolution mixing up and down Programmable mixing Optional 120 CCPM Swashplate mixing Separate trim setting for all flight modes A special unwanted interference limiter ignores signals outside of the R700s band width when the receiver is on and the transmitter is off. The limiter also prevents servos from random glitching when other transmitters are operating in close proximity. The electrical circuitry is state-of-the-art surface mount technology (SMT). These SMT components draw less current, thus increasing flying time. Flush mounting of these components also reduces the risk of vibration, wear, and damage.

For the initial charge, leave the charger and batteries hooked up for 2024 hours in order to fully charge both battery packs to peak capacity. For subsequent charges, leave the charger and batteries hooked up overnight (approximately 16 hours). The charger supplied with this system is designed to recharge your transmitter battery at a rate of 50mA. The receiver battery pack will charge at 50mA for the 600mAh airplane battery pack and at 150mA for the 1000mAh helicopter battery pack. Transmitter Only The center pin on all JR remote control systems is negative. Therefore, the center pin on all JR chargers is negative, not positive. This is different from any other manufacturers chargers and radio systems. Beware of improper connections based on color code wire leads, as they do not apply in this instance. You must make certain that the center pin of your JR transmitter is always connected to the negative voltage for correct polarity hookup. 4.2 CHARGER RIGHT SIDE OF TRANSMITTER CENTER PIN IS NEGATIVE OUTSIDE IS POSITIVE CHARGER PIGTAIL FOR TRANSMITTER BLACK TO POSITIVE RED TO NEGATIVE CHARGER PIGTAIL FOR RECEIVER REDPOSITIVE / BROWNNEGATIVE / ORANGESIGNAL The pilot lamps should always be on during the charging operation. If they are not, check to make sure you have turned off both the transmitter and receiver. Do not use the charger for equipment other than JR. The charging plug polarity may not be the same and equipment damage may result. Do not use other manufacturers after-market accessories that plug into the transmitters charging jack. If you do, any damage that results will not be covered by warranty. If you are unsure of compatibilities with your radio, seek expert advice before doing anything to avoid possible damage. During the charging operation, the chargers temperature is slightly elevated. This is normal. XP662 MANUAL Introduction 13 3984 JR XP662 Manual 1/21/02 1:11 PM Page 14 CHAPTER 5: TRAINER SYSTEM Introduction 5 TRAINER SYSTEM The XP662 features a built-in trainer system. The transmitter can be used as either a master (trainer) or as a slave (trainee). The XP662 is compatible with all other current JR radios that have built-in trainer systems. An optional Trainer Cord (JRPA130) is needed . TRAINER BUTTON D.S.C.

When a trim input is given, the display screen will automatically change to show the trim value for current channel being adjusted. Once the trim change has been completed, the screen will automatically return to the previous screen display after 23 seconds. A significant feature found only with Digital Trims is the ability for the XP662 to automatically store the trim values in the system memory. This eliminates the need for previously found software functions like Trim Offset Memory, Rudder Offset Memory (Heli), and Stunt Trim (Heli). In Heli mode, the XP662's digital trims provide a separate set of trim values for each Flight mode
(Normal, Stunt, and Throttle Hold), which takes the place of the previously needed Stunt Trim function. With this feature, the trim levers are active in all flight modes, and will store the trim values for each mode independantly. This feature also takes the place of the previously needed rudder offset function, since there is now a completely separate set of trim setting for the Throttle Hold mode.

AUX 1 Auxiliary 1 Channel (Flap) Transmitter Throttle ALT The Throttle ALT function makes the throttle stick trim active only when the throttle stick is less than half throttle. This gives easy, accurate idle adjustments without affecting the high throttle position. 1.4 TRANSMITTER Note: Your transmitter has a 5-year lithium battery to protect your pre-programmed data against main transmitter battery failure. If your system reads 0.0 volts or has an unfamiliar display (service mode) or your data resets to the factory defaults, return your transmitter to Horizon Service Center (see page 85) for lithium battery replacement.

(Factory Installed) TRAINER JACK TRANSMITTER CASE SCREW Transmitter Crystal Replacement Notice The Federal Communications Commission (FFC) requires that changes in transmitter frequency must be performed only by an authorized service technician (Horizon Service Center). Any transmitter frequency change made by non-certified technician may result in a violation of the FCC rules. 16 XP662 MANUAL Airplane 3984 JR XP662 Manual 1/21/02 1:11 PM Page 17 CHAPTER 1: TRANSMITTER CONTROLS Airplane 1.5 CONTROL STICK LENGTH ADJUSTMENT To adjust the control stick length, use a 2mm Allen wrench to unlock the set screw located inside the end of the control stick. Turn the set screw counterclockwise to loosen it, then turn the knurled portion of the stick to adjust the length. Counterclockwise will lengthen the stick and clockwise will shorten it. After the control stick(s) has been adjusted to suit your flying style, tighten the set screw. 1.6 DIRECT SERVO CONTROL (DSC) SET SCREW LOOSEN TIGHTEN For proper DSC hook-up and operation:
1. Leave the transmitter power switch off. The transmitter will not transmit any radio frequency (RF) in this position. 2. Plug the optional DSC Cord (JRPA132) into the DSC port in the rear of the transmitter. 3. The encoder section of the transmitter will now be operational and the LCD display will be lit. 4. Plug the other end of the DSC Cord into the receiver charge receptacle. Turn on the switch harness. Note: When installing the optional charging jack (JRPA024), be sure to hook the charging jack receptacle securely into the switch harness charge cord. Why you should use the DSC function:
1. The DSC enables you to check the control surfaces of your airplane without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw 70mAh when using the DSC function. Note: You will need to purchase (separately) both the DSC Cord (JRPA132) and the JR Deluxe Switch Harness (JRPA001) to make use of the XP662 DSC function. 2. The DSC function allows you to make final adjustments to your airplane or helicopter without transmitting any radio signals. Therefore, if another pilot is flying on your frequency, you can still adjust your aircraft and not interfere with the other aircraft. Note: Under no circumstances should you attempt to fly your aircraft with the DSC Cord plugged in! This feature is for bench checking your aircraft only. ACharge Cord/DSC Receptacle BSwitch Harness Lead CCharger/DCS Cord B A C 1.7 NECK STRAP ATTACHMENT There is an eye hook on the front of the transmitter for attaching an optional neck strap (JRPA023). The eye hook is precisely positioned (see Section 1.1) so that the transmitter will be perfectly balanced when a neck strap is used. XP662 MANUAL Airplane 17 3984 JR XP662 Manual 1/21/02 1:11 PM Page 18 CHAPTER 2: CONNECTIONS Airplane 2.1 INSTALLATION REQUIREMENTS Please read and carefully follow these suggestions. 1. For added protection, wrap the RX and the RX Ni-Cd in foam rubber that is at least 1/4 thick. 2. Run the RX antenna through the fuselage and make sure it is fully extended. Never cut or bundle your RX antennathis will decrease range and performance. 3. Rubber servo grommets are included with your radio system and should be installed in the servo flanges. The servos should then be mounted on either hardwood rails or a plywood tray with the mounting screws provided. Do not overtighten the mounting screws. The flange of the brass eyelets should face down (toward the wood). 4. All servos must be able to move freely over the full range of their travel. Make sure the linkages do not impede servo travel. A stalled servo will drain the battery pack within a few minutes. 5. Before installing servo output arms, make sure 6. the servo is in its neutral position. In the case of gas-powered model aircraft, mount the receiver power switch on the side of the fuselage opposite the muffler to protect the switch from exhaust residue. With other types of models, mount the switch in the most convenient place. Make sure that the switch operates freely and is capable of traveling its full distance. 7. With your model sitting on the ground and the transmitter antenna collapsed, check that your system works at a distance of 75 to 100 feet. If your system stops functioning at a distance that is shorter than listed above, please contact the Horizon Service Center for further information prior to flying your model. 2.2 CONNECTIONS RECEIVER BATTERY 4N-600 O F F O N ON/OFF SWITCH HARNESS

This allows a single switch to be used when moving from high rates for wild maneuvers to low rates for mild maneuvers. Exponential Rate
(EXP) is also available for both aileron and elevator and works in conjunction with the dual rate function to provide mild control movements around neutral while allowing maximum servo travel. This reduces sensitivity in the middle portion of the stick control and still allows full travel at the end of the stick control. Refer to section 7.3 for exponential rate adjustment.

The flaperon feature mixes flaps with ailerons so the ailerons can be drooped for takeoffs and landings while still functioning fully as ailerons. V-Tail Mixing combines rudder and elevator for V-Tail operations. The Delta Wing function allows the aileron to also act as the elevator, while retaining independent use of both functions. The Delta Wing function allows the ailerons to also act as the elevator, while retaining independent use of both functions. Flaperon Setup When using flaperon mixing, two servos (one for each aileron) must be used. Connect the left aileron servo to channel #6 (Aux 1) and the right aileron servo to channel #2 (Aile) in the receiver. Individual functions (e.g., servo reversing, sub-trims, etc.) are still available for each of the channels. Use sub-trims for individual neutral adjustment. Adjust the aileron travel values by increasing or decreasing the aileron dual rate. Flap adjustments are made with flap left/right travel adjustment described in Section 7.5. Also see Aileron Differential in Section 6.18. V-Tail V-Tail Mixing requires two servos. Connect the left tail servo to channel #3 (Elev) and the right tail servo to channel #4 (Rudd) in the receiver. Individual functions (e.g., servo reversing, sub-trims, etc.) are available for each servo. Use sub-trims for individual neutral adjustments described in Section 7.4. V-Tail elevator travel is adjusted by elevator dual rates described in Section 7.2. Delta-Wing Mixing Delta or Elevon Mixing as it is commonly known, is the final wing mixing selection in your XP652. This style of aircraft also employs two wing servos. However, in essence, there is not an elevator present. Instead, at an elevator stick input, the two wing servos function in conjunction with one another in the same direction to create an up/down movement of the aircraft. Also, when an aileron control is given, the two wing servos move in opposite directions to function as ailerons as well.

You can select from either PPM (FM), Z-PCM or S-PCM,depending on the central processing unit within your receiver to utilize existing receivers, or to upgrade your XP662 flight pack for future models. Your system comes factory preset in the FM or PPM (Pulse Position Modulation) position so that it is compatible with the included R700 FM receiver. Please refer to the receiver compatibility chart below when selecting the modulation type for various JR receivers. Note: Once the proper modulation has been selected for a specific model number, the modulation type will remain the same for that model number, even during model number/type changes. In other words, if you have one model on FM/PPM and one model on PCM, the system will automatically change modulation types once the correct modulation has been selected for that model.

This function is designed to help minimize damage to your airplane during a loss of signal to the receiver. The servos either assume the fail-safe presets or hold the last good signal position. Note: In the PCM modulations, the Fail-Safe/Hold function cannot be totally disabled so that the servos will react to interference in the same way as they do in a PPM system. This is only possible with the use of a PPM receiver and the transmitter in the PPM modulation. Note: Since the actual screen appearance varies, depending on the modulation of your radio, refer to the appropriate modulation section which follows
(Z-PCM, S-PCM). As noted earlier, if you are in the PPM modulation, the Fail-Safe/Hold function is not applicable. Therefore, the Fail-Safe/Hold function will not appear on your LCD in the PPM mode. Refer to the Modulation Selection section for more information pertaining to the broadcast signal of your XP662 transmitter. 6.9 FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION Hold (Z-PCM) The Hold function is automatically activated when the radio is turned on and is in the Z-PCM modulation. When a clear signal is restored, the Hold function releases, and control of the airplane returns to you. This function stops (or holds) the servos in the positions they were in just prior to the interference. Therefore, your airplane maintains the position held immediately before the interference was experienced. Accessing Fail-Safe/Hold (Z-PCM) When the Fail-Safe function is activated (i.e., when the signal is interrupted), the transmitter automatically moves each servo to a preset position. The position that each servo assumes is determined by you, as is the time length of interference that must occur before servo movement. If you would prefer your control surfaces to move to a chosen position during a loss of signal, please refer to the time delay/memory section below. moment the interference occurs, until the servos assume their preset positions. 1. Press the SCROLL and INCREASE button simultaneously and hold. 2. Turn on the transmitter to enter the System mode. 3.

Press the SCROLL button until FSM appears on the screen. 2. Set all controls to the desired fail-safe position, then press the CHANNEL and INCREASE buttons simultaneously. A high-pitch beep sound will confirm that the preset positions have been entered. 3. Hold the transmitter sticks in the position that you want the servos to assume during signal loss conditions. You can determine fail-safe preset positions for the other channels by placing the control knobs and switches in the positions that you want them to assume during interference. 4. With the sticks, switches and control knobs in the fail-safe positions, press the CHANNEL and INCREASE buttons simultaneously. This will enter these locations as the fail-safe memory settings. A high-pitched beep will indicate that this setting has been stored. 5. To confirm that the input of data was successful, switch the transmitter off. The controls will move to the input locations. If not, repeat Step 4 again. 6. To exit the Fail-Safe function, press the SCROLL and INCREASE buttons simultaneously. Note: These preset positions remain stored in the transmitters memory until both the transmitter battery pack and the lithium back-up battery have been removed (or until data reset has been performed). Therefore, you do not have to reset the fail-safe each time you fly. Should you want to re-adjust the fail-
safe presets, access the Fail-Safe function and adjust the presets as you havejust done. The transmitter automatically recalls the settings for the last fail-safe adjustment. XP662 MANUAL Airplane 31 3984 JR XP662 Manual 1/21/02 1:11 PM Page 32 CHAPTER 6: FUNCTIONS (SYSTEM MODE) Airplane 6.10 FAIL-SAFE/HOLD FUNCTION IN S-PCM MODULATION Hold Function (S-PCM) The Hold function is automatically activated when the radio is turned on and in the S-PCM modulation. This function stops (or holds) the servos in the positions they were in just prior to the interference. Therefore, your aircraft maintains the position held immediately before the interference was experienced. When a clear signal is restored, the Hold function releases, and control of the airplane returns to you. Fail Safe/Hold Combination in S-PCM Modulation The XP662 allows you to combine the hold and fail-
safe presets for all six channels on the receiver. You can select fail-safe or hold independently for all channels on your aircraft. In other words, some channels will hold their last clear signal position, while others assume the preset position. Once the fail-safe has been activated by signal interruption
(interference), the transmitter automatically moves the servos to a preset position. The predetermined servo positions are set byyou. In the S-PCM fail-safe, the time delay (the amount of time it takes, starting the moment the interference occurs, until the servos assume the preset positions) is fixed at .3, or 1/3, second. After the interference has ceased, normal operation of the airplane returns to you immediately. 32 XP662 MANUAL Airplane 3984 JR XP662 Manual 1/21/02 1:11 PM Page 33 CHAPTER 6: FUNCTIONS (SYSTEM MODE) Airplane 6.10 FAIL-SAFE/HOLD FUNCTION IN S-PCM MODULATION (continued) Activating Servo Fail-Safe Presets by Channel (S-PCM) 1.

The purpose of this function is to allow for in-flight selection of two preset servo travels for each of these channels. The amount of travel is adjustable from 0-125%. The factory settings for both switch positions (0 and 1) is 100%. Either position may be selected as the low or high rate by placing the switches in the desired position and adjusting the value for that position. Operation of these switches is described in Section 6.3. Different types of maneuvers require varying amounts of control movements. Snap rolls require large control movements, while smooth maneuvers like long slow rolls are best performed with smaller control movements. Dual rates allow you to change the control movements in flight at the flip of a switch. This allows you to execute maneuvers requiring both radical control movements and small control movements during a single flight.

XP662 MANUAL Airplane 35 3984 JR XP662 Manual 1/21/02 1:11 PM Page 36 CHAPTER 7: FUNCTIONS (FUNCTION MODE) Airplane 7.3 EXPONENTIAL Programmable exponential adjustments are offered on the aileron and elevator channels of your XP662 system. Exponential is a function that allows you to tailor the response rate of the controls as compared to the stick inputs. The purpose of exponential is to reduce the sensitivity in the middle portion of stick movement, while still allowing full travel at the end of the stick movement. In other words, the end result
(travel) remains the same, although exponential changes the rate at which it achieves this travel. The adjustable range of the Exponential function is from 0100%. Zero percent (0%) is linear stick control which means that the response rate is equal throughout the stick control. One hundred percent
(100%) is full exponential. The larger the exponential value, the less servo action, or sensitivity, you will notice around the neutral setting. Note: The Exponential function operates in conjunction with the Dual Rate function. It is imperative to understand the Dual Rate function prior to adjusting the exponential values. Exponential may be selected independently for either the high or low rate (position 0 or 1) or both. Note: The dual rate switch position is changed/accessed by setting the appropriate dual rate switch to the 0 or 1 positions. ENTER SCROLL CHANNEL INCREASE DECREASE EXP A I O 0 %

Sub-trim is particularly useful as it allows the mechanical trim levers to be returned to their neutral positions by adjusting/
changing the servos neutral position electronically, without the need to mechanically adjust the specific control linkage. This allows the same mechanical trim lever settings between the four models you can control with this radio system. Sub-trim can also allow additional trim travel when mechanical trims do not provide enough movement. Note: It is recommended to use as little subtrim as possible for adjustment. If more that 2030 points are required, is it suggested that a mechanical linkage adjustment be performed.

The functions allow mixing any one channel to any other channel. The mix can remain ON at all times, or be switched OFF in flight using a number of different switches.
(Refer to Chart A). Each channel is identified by channel numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc.See Chart B) The channel appearing first is known as the master channel, or the channel to which you want to mix. The second channel is known as the slave channel or the channel that is being mixed into the master channel. For example, AILE-
RUDD would indicate aileron-to-rudder mixing. Each time the aileron stick is moved, the aileron will deflect, and the rudder will automatically move in the direction and to the value input. Mixing is proportional, so small inputs of the master channel will produce small outputs of the slave channel. Each programmable mix has a mixing offset. The purpose of the mixing offset is to redefine the neutral position of the slave channel.

Turn the set screw counterclockwise to loosen it, then turn the knurled portion of the stick to adjust the length. Counterclockwise will lengthen the stick and clockwise will shorten it. After the control stick(s) has been adjusted to suit your flying style, tighten the set screw back. 1.5 DIRECT SERVO CONTROL (DSC) SET SCREW LOOSEN TIGHTEN For proper DSC hook-up and operation:
1. Leave the transmitter power switch off. The transmitter will not transmit any radio frequency
(RF) in this position. 2. Plug the optional DSC Cord (JRPA132) into the DSC port in the rear of the transmitter. 3. The encoder section of the transmitter will now be operational and the LCD display will be lit. 4. Plug the other end of the DSC Cord into the receiver charge receptacle. Turn on the switch harness. Note: When installing the optional Charging Jack (JRPA025), be sure to hook the charging jack receptacle securely into the switch harness charge cord. Why you should use the DSC function:
1. The DSC enables you to check the control surfaces of your aircraft without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw 70mAh when using the DSC function. Note: You will need to purchase (separately) both the DSC Cord (JRPA132) and the JR Deluxe Switch Harness (JRPA001) to make use of the XP662 DSC Function. 2. The DSC function allows you to make final adjustments to your airplane or helicopter without transmitting any radio signals. Therefore, if another pilot is flying on your frequency, you can still adjust your aircraft and not interfere with the other aircraft. Note: Under no circumstances should you attempt to fly your aircraft with the DSC Cord plugged in!
This feature is for bench checking your aircraft only.

XP662 MANUAL Helicopter 51 3984 JR XP662 Manual 1/21/02 1:11 PM Page 52 CHAPTER 2: CONNECTIONS Helicopter 2.1 INSTALLATION REQUIREMENTS Please read and carefully follow these suggestions. 1. For added protection, wrap the RX and the RX Ni-Cd in foam rubber that is at least 1/4 thick. 2. Run the RX antenna through the fuselage and make sure it is fully extended. Never cut or bundle your RX antennathis will decrease range and performance. 3. Rubber servo grommets are included with your radio system and should be installed in the servo flanges. The servos should then be mounted on either hardwood rails or a plywood tray with the mounting screws provided. Do not overtighten the mounting screws. The flange of the brass eyelets should face down (toward the wood). 4. All servos must be able to move freely over the full range of their travel. Make sure the linkages do not impede servo travel. A stalled servo will drain the battery pack within a few minutes. 5. Before installing servo output arms, make sure 6. the servo is in its neutral position. In the case of gas-powered model aircraft, mount the receiver power switch on the side of the fuselage opposite the muffler to protect the switch from exhaust residue. With other types of models, mount the switch in the most convenient place. Make sure that the switch operates freely and is capable of traveling its full distance. 7. With your model on the ground and the trans-
mitter antenna collapsed, check that your system works at a distance of 75 to 100 feet. If your system stops functioning at a distance that is shorter than listed above, please contact the Horizon Service Center for further information prior to flying your model. 2.2 CONNECTIONS G460T GYRO

This allows a single switch to be used when moving from high rates for wild maneuvers to low rates for mild maneuvers. Exponential Rate (EXP) is also available for both aileron and elevator and works in conjunction with the dual rate function to provide mild control movements around neutral while allowing maximum servo travel. This reduces sensitivity in the middle portion of the stick control and still allows full travel at the end of the stick control. Refer to section 7.3 for exponential rate adjustment.

This feature is for use with gyros that offer a dual rate sensitivity adjustment, such as the JR G460T Piezo Gyro (JRPG460T). The most common use for this feature would be to combine the gyro dual rate adjustment with the flight mode switch. This would then automatically alter the gyro sensitivity from normal (hover) to flight (forward flight) when the flight mode switch is in use.

You can select from either PPM (FM), Z-PCM or S-PCM,depending on the central processing unit within your receiver to utilize existing receivers, or to upgrade your XP662 flight pack for future models. Your system comes factory preset in the FM or PPM (Pulse Position Modulation) position so that it is compatible with the included R700 FM receiver. Please refer to the receiver compatibility chart below when selecting the modulation type for various JR receivers. Note: Once the proper modulation has been selected for a specific model number, the modulation type will remain the same for that model number, even during model number/type changes. In other words, if you have one model on FM/PPM and one model on PCM, the system will automatically change modulation types once the correct modulation has been selected for that model.

This function is designed to help minimize damage to your airplane during a loss of signal to the receiver. The servos either assume the fail-safe presets or hold the last good signal position. Note: In the PCM modulations, the Fail-Safe/Hold function cannot be totally disabled so that the servos will react to interference in the same way as they do in a PPM system. This is only possible with the use of a PPM receiver and the transmitter in the PPM modulation. Note: Since the actual screen appearance varies, depending on the modulation of your radio, refer to the appropriate modulation section which follows
(Z-PCM, S-PCM). As noted earlier, if you are in the PPM modulation, the Fail-Safe/Hold function is not applicable. Therefore, the Fail-Safe/Hold function will not appear on your LCD in the PPM mode. Refer to the Modulation Selection section for more information pertaining to the broadcast signal of your XP662 transmitter. 6.9 FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION Hold (Z-PCM) The Hold function is automatically activated when the radio is turned on and is in the Z-PCM modulation. When a clear signal is restored, the Hold function releases, and control of the airplane returns to you. This function stops (or holds) the servos in the positions they were in just prior to the interference. Therefore, your airplane maintains the position held immediately before the interference was experienced. Accessing Fail-Safe/Hold (Z-PCM) When the Fail-Safe function is activated (i.e., when the signal is interrupted), the transmitter automatically moves each servo to a preset position. The position that each servo assumes is determined by you, as is the time length of interference that must occur before servo movement. After the interference has ceased, control of the airplane returns immediately to you. There are three time delays to choose from: 1/3 (0.3) second, 1/2(0.5) second and 1.0 second. These time delays are the amount of time it takes, starting the XP662 MANUAL Helicopter If you would prefer your control surfaces to move to a chosen position during a loss of signal, please refer to the time delay/memory section below. moment the interference occurs, until the servos assume their preset positions. 1. Press the SCROLL and INCREASE buttons simultaneously and hold. 2. Turn on the transmitter to enter the System mode. 3. Press the SCROLL button until FST appears on the screen. Note: If Fail-Safe does not appear on your LCD, it is because you are transmitting in PPM. Fail-Safe is not applicable in the PPM mode. Refer to the Modulation Mode Selection section for more information. 63 3984 JR XP662 Manual 1/21/02 1:11 PM Page 64 CHAPTER 6: FUNCTIONS (SYSTEM MODE) Helicopter 6.9 FAIL-SAFE/HOLD FUNCTION IN Z-PCM MODULATION (continued) Setting Fail-Safe/Hold Time Delay/Memory In Z-PCM Modulation 1.

Set all controls to the desired fail-safe position, then press the (+) and (-) buttons simultaneously. A high pitch beep sound will confirm that the preset positions have been entered. 3. Hold the transmitter sticks in the position that you want the servos to assume during signal loss conditions. You can determine fail-safe preset positions for the other channels by placing the potentiometers and switches in the positions that you want them to assume during interference. 4.

The controls will move to the input locations. If not, repeat Step 4 again. 6. To exit the Fail-Safe function, press the SCROLL and INCREASE buttons simultaneously. Note: These preset positions remain stored in the transmitters memory until both the transmitter battery pack and the lithium back-up battery have been removed (or until data reset has been performed). Therefore, you do not have to reset the fail-safe each time you fly. Should you want to re-adjust the fail-
safe presets, access the Fail-Safe function and adjust the presets as you have just done. The transmitter automatically recalls the settings for the last fail-safe adjustment. 64 XP662 MANUAL Helicopter 3984 JR XP662 Manual 1/21/02 1:11 PM Page 65 CHAPTER 6: FUNCTIONS (SYSTEM MODE) Helicopter 6.10 FAIL-SAFE/HOLD MEMORY IN S-PCM MODULATION Hold Function (S-PCM) The Hold function is automatically activated when the radio is turned on and in the S-PCM modulation. This function stops (or holds) the servos in the positions they were in just prior to the interference. Therefore, your aircraft maintains the position held immediately before the interference was experienced. When a clear signal is restored, the hold function releases, and control of the airplane returns to you. Fail-Safe/Hold Combination in S-PCM Modulation The XP662 allows you to combine the hold and fail-
safe presets for all six channels on the receiver you can select fail-safe or hold independently for all channels on your aircraft. In other words, some channels will hold their last clear signal position, while others assume the preset position. Once the fail-safe has been activated by signal interruption
(interference), the transmitter automatically moves the servos to a preset position. The predetermined servo positions are set byyou. In the S-PCM fail-safe, the time delay (the amount of time it takes, starting the moment the interference occurs, until the servos assume the preset positions) is fixed at .3, or 1/3, second. After the interference has ceased, normal operation of the airplane returns to you immediately.

The purpose of this function is to allow for in-flight selection of two preset servo travels for each of these channels. The amount of travel is adjustable from 0-125%. The factory settings for both switch positions (0 and 1) is 100%. Either position may be selected as the low or high rate by placing the switches in the desired position and adjusting the value for that position. Operation of these switches is described in Section 6.3. Different types of maneuvers require varying amounts of control movements. Snap rolls require large control movements, while smooth maneuvers like long slow rolls are best performed with smaller control movements. Dual rates allow you to change the control movements in flight at the flip of a switch. This allows you to execute maneuvers requiring both radical control movements and small control movements during a single flight.

Exponential is a function that allows you to tailor the response rate of the controls as compared to the stick inputs. The purpose of exponential is to reduce the sensitivity in the middle portion of stick movement, while still allowing full travel at the end of the stick movement. In other words, the end result
(travel) remains the same, although exponential changes the rate at which it achieves this travel. The adjustable range of the Exponential function is from 0100%. Zero percent (0%) is linear stick control which means that the response rate is equal throughout the stick control. One hundred percent
(100%) is full exponential. The larger the exponential value, the less servo action, or sensitivity, you will notice around the neutral setting. Note: The Exponential function operates in conjunction with the Dual Rate function. It is imperative to understand the Dual Rate Function prior to adjusting the exponential values. Exponential may be selected independently for either the high or low rate (position 0 or 1) or both. Note: The dual rate switch position is changed/ accessed by setting the appropriate dual rate switch to the 0 or 1 positions. ENTER SCROLL CHANNEL INCREASE DECREASE EXP A I O 0 %

Sub-trim is particularly useful as it allows the mechanical trim levers to be returned to their neutral positions by adjusting
/changing the servos neutral position electronically, without the need to mechanically adjust the specific control linkage. This allows the same mechanical trim lever settings between the five models you can control with this radio system. Sub-trim can also allow additional trim travel when mechanical trims do not provide enough movement. Note: It is recommended to use as little subtrim as possible for adjustment. If more that 2030 points are required, is it suggested that a mechanical linkage adjustment be performed.

The adjustment range is from 0% to 150%. Travel adjustment is factory set at 100% for all channels. The travel adjustment value displayed on the screen depends on the position of the stick or switch (e.g., flap switch, gear switch). This function is useful either to maximize control surface travel or to reduce travel to eliminate servo binding without the need for mechanical adjustment.

When properly adjusted, the helicopter will climb and descend without a tendency to yaw in either direction. Revolution mixing is for use with non heading lock gyros only. Since the torque created by the main rotor blades varies with different throttle/pitch settings, it is necessary for the tail rotor blades to change pitch at the same time. The U or up mixing adjusts the tail rotor compensation from the mid to high throttle stick setting. The D or down mixing adjusts the tail rotor compensation from the mid to the low throttle stick setting. Thus, if you were to move the throttle from the low to high positions, the tail rotor servo will move from the D to the U settings. Revolution Mixing Set-up Procedure First, set up the helicopter so that it will maintain a stable hover with the tail rotor trim in the center position. Next, bring the helicopter into a steady vertical climb. The body of the helicopter will move in the opposite direction to the main rotor rotation. Increase the U or up mixing until the helicopter climbs without the tendency to rotate. At a safe altitude, reduce the throttle. The helicopter will descend, and the body will turn in the same direction as the main rotor blades. Increase the D or down mixing until the helicopter descends without the tendency to rotate.

The functions allow mixing any one channel to any other channel. The mix can remain on at all times or be switched off in flight using a number of different switches. (Refer to Chart A). Each channel is identified by channel numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc. see Chart B) The channel appearing first is known as the Master Channel or the channel to which you want to mix. The second channel is known as the Slave Channel or the channel that is being mixed into the Master Channel. For example, ELEV-AILE would indicate elevator-to-aileron mixing each time the elevator stick is moved, the elevator will deflect, and the aileron will automatically move in the direction and to the value input. Mixing is proportional, so small inputs of the master channel will produce small outputs of the slave channel. Each programmable mix has a mixing offset. The purpose of the mixing offset is to redefine the neutral position of the slave channel. The elevator-aileron mix mentioned above is most commonly used to help trim the helicopter for proper loop tracking. This type of mix should be used only by pilots who are comfortable with their programming abilities with the XP662.

CCPM is a type of pitch mixing where the three servos are connected directly to the swashplate of the helicopter and physically move both in unison and independently for all changes in pitch/
cyclic. Please refer to the diagram below for proper 120 Three Servo-CCPM identification and connection.

(Pitch). The labeling of these servos can become quite confusing because with the CCPM function, the three servos no longer work independently, but rather as a team, and their functions are now combined. For this reason, we will refer to the three servos in the following manner:
Aileron Servo: We will refer to this servo as the Left servo. The channel number for this servo when using a JR radio is CH2. Elevator Servo: We will refer to this servo as the Front servo. The channel number for this servo when using a JR radio is CH3. AUX 1 (Pitch) Servo: We will refer to this servo as the Right servo. The channel number for this servo when using a JR radio is CH6. Please refer to the CCPM connections chart below for clarification. For non-JR radios, please consult your radio instructions for proper connection. G460T G4605 GYRO (OPTIONAL)

The radios 120 Three-Servo CCPM function automatically mixes the three servos to provide the correct mixing inputs for aileron (roll), elevator
(pitch), and collective. The following is an example of how each control input affects the servos movement:
3. Aileron (Roll) When an aileron (roll) input is given, the two rear servos (B and C) travel in opposite directions, while the front servo (A) remains motionless. For example, when a left aileron (roll) command is given, the left rear servo (C) will move downward, while the right rear servo (B) will move upward to tilt the swashplate to the left. As mentioned, the front servo (A) will remain motionless. The travel value for each of the two rear servos is 100%. 1. Collective Please refer to the diagram below for clarification. Front of Helicopter Elevator Axis 120 CCPM Control System When a collective pitch input is given, all three servos (A, B, and C) move together in the same direction, at equal amounts, to raise and lower the swashplate while keeping the swashplate level. During this function, all three servos travel at the same value (100%) so that the swashplate can remain level during the increase and decrease in pitch. As mentioned, this mixing of the three servos is achieved through the radios CCPM program. 2. Elevator (Pitch) When an elevator input is given, all three servos must move to tilt the swashplate fore and aft, but their directions vary. The two rear servos (B and C) move together in the same direction, while the front servo (A) moves in the opposite direction. For example, when an up elevator (back cyclic) command is given, the two rear servos (B and C) will move downward, while the front servo (A) moves upward so that the swashplate will tilt aft. During this function, the front servo (A) travels at 100%, while the two rear servos (B and C) travel at 50% (1/2 the travel value) of the front servo. This difference in travel is necessary due to the fact that the position of the front control ball is two times the distance of the two rear control ball position as measured from the center of the swashplate. As mentioned, this mixing of the three servos is also achieved through the radios CCPM program. XP662 MANUAL Helicopter 81 3984 JR XP662 Manual 1/21/02 1:12 PM Page 82 CHAPTER 7: FUNCTIONS (FUNCTION MODE) Helicopter 7.13 HOW 120 CCPM WORKS (continued) 120 Three-Servo CCPM Swashplate Mixing The JR 120 CCPM or Cyclic/Collective Pitch Mixing system offers the user a control system that can accomplish the same control inputs as the One-Servo Standard system, but with increased precision and reduced complexity. As with the One-Servo system, the JR CCPM system utilizes three servos for the three main controls:
aileron (roll), elevator (pitch) and collective. The CCPM lower swashplate ring is designed with only three control balls, spaced at 120 from each other, hence the 120 CCPM designation. Although the control balls are not at 90 as in the standard system, the aileron (roll) axis is still parallel to the main mechanics of the helicopter, and the elevator (pitch) axis still functions at 90 to the mechanics as does the One-Servo System. Please refer to the diagram below for clarification. The main and important difference in the way that these two systems operate is that unlike the One-
Servo system where the three servos work completely independent from each other, the CCPM systems work as a team to achieve the same control inputs. For example, if an aileron (roll) input is given, two servos work together to move the swashplate left and right. If an elevator (pitch) input is given, all three servos work together to move the swashplate fore and aft. For collective, its also the strength of three servos that will move the swashplate up and down the main rotor shaft. With two to three servos working at the same time during any given control input, servo torque is maximized and servo centering is also increased. In addition to these benefits, CCPM achieves these control responses without the need for complex mechanical mixing systems that require many more control rods and parts to set up. 120 Elevator Axis Aileron Axis 120 Three-Servo CCPM Control System This amazing CCPM control is achieved through special CCPM Swashplate Mixing that is pre-programmed into many of todays popular radio systems. Since the 120 CCPM function is pre-programmed, CCPM is no more complicated to set up than a conventional One-Servo Standard system. When you factor in the reduced parts count and easy programming, CCPM is actually easier to set up and operate than many conventional systems. 82 XP662 MANUAL Helicopter 3984 JR XP662 Manual 1/21/02 1:12 PM Page 83 CHAPTER 8: DATA SHEET Helicopter 8 Data Sheet Modulation S-PCM Z-PCM PPM (FM) Model Number ______________________ Model Name ________________________ CHANNEL

Unfortunately, they can also pose a potential hazard if not maintained and operated properly. It is imperative that you install your radio control system correctly. Additionally, your level of piloting competency must be high enough to ensure that you are able to control your aircraft under all conditions. If you are a newcomer to radio controlled flying, please seek help from an experienced pilot or your local hobby shop. Listed below are some safety Dos and Donts that must be followed by all pilots:
Ensure that your batteries have been properly charged prior to initial flight. Keep track of the time that the system is turned on so that you will have an idea of how long you can safely operate your system. Perform a ground range check prior to the initial flight of the day. See the Daily Flight Checks section below for information on how to do so. Check all control surfaces prior to each takeoff. Use frequency flags. Do not fly your model near spectators, parking areas, or at any other area that could result in injury to people or damage of property. Do not fly during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your aircraft. Strong winds can cause similar problems. Do not fly unless your frequency is clear. Warning: Only one transmitter at a time can operate on a given frequency. If you turn on your transmitter while someone else is operating a model on your frequency, both pilots will lose control of their models. Only one person can use a given frequency at a time. It does not matter if it is AM, FM, or PCMonly one frequency at a time. Do not point the transmitter antenna directly toward the model. The radiation pattern from the tip of the antenna is inherently low. Do not take chances. If at any time during flight you observe any erratic or abnormal operation, land immediately and do not resume flight until the cause of the problem has been ascertained and corrected. 2 DAILY FLIGHT CHECKS 1. Check the battery voltage on both the transmitter Do not extend the transmitter antenna at this and the receiver battery packs. Do not fly below 9.0 volts on the transmitter or below 4.7 volts on the receiver. To do so can cause a crash of your aircraft. Note: When you check these batteries, ensure that you have the polarities correct on your expanded scale voltmeter. 2. Check all hardware (linkages, screws, nuts, bolts) prior to each days flight. Be sure that binding does not occur and that everything is properly secured. 3. Ensure that all surfaces are moving in the proper manner. 4. Perform a ground range check before each days flying session. The range check should be as follows:
time. Turn the transmitter on. Turn the model on. Slowly walk away from the model while moving the control surfaces. The aircraft should function properly at a distance of 75 to 100 feet. 5. Prior to starting your aircraft, turn off your transmitter then turn it back on. Do this each time you start your aircraft. If any critical switches are on without your knowledge, the transmitter alarm will warn you. 6. Ensure that all trim levers are in the proper location. 7. Be sure that all servo pigtails and switch harness plugs are secured in the receiver. Make sure that the switch harness moves completely in both directions. 84 XP662 MANUAL Important Information 3984 JR XP662 Manual 1/21/02 1:12 PM Page 85 IMPORTANT INFORMATION 3 WARRANTY COVERAGE Your new equipment is warranted to the original purchaser against manufacturer defects in material and workmanship for one year from the date of purchase.
