CHARGING YOUR QUATTRO RADIO SYSTEM PRIOR TO INSTALLATION Your Quattro Radio System is shipped from the factory with both the transmitter and receiver NiCad batteries in a discharged state. Before attempting to install/operate your Quattro System, it is important that the system be charged for approximately 24 hours to ensure that both transmitter and receiver packs are at peak capacity. Special note on J-line transmitter charge polarity:
The center pin of the charge receptacle on all J-line brand radio systems is Negative polarity. Therefore, the center pin on all J-line or JR chargers is negative, not positive. Your J-line radio systems charge polarity is reversed from many other manufacturers chargers. Beware of improper polarity connections based on color code wire leads as they DO NOT APPLY in this instance. You must always be certain that the center pin on any charger used with this system is wired for negative polarity, otherwise damage will occur to the charge circuit of the Quattro. The J-line warranty does not cover any system that is damaged by reverse polarity charging. Under normal conditions, subsequent recharging of your Quattro System will require only an overnight charge (approximately 16 hours) to attain peak charge capacity. The charger supplied with this system is designed to recharge your transmitter and receiver batter packs at a rate of 50mAh. Right Side of Transmitter Charging Jack Center Pin is Negative Outside is Positive Charger Pigtail for Transmitter Black to Positive Red to Negative Charger Pigtail for Receiver Red-Positive/Brown-Negative/Orange-Signal 8.1 BATTERY CHARGER The pilot lamps on the battery charger 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 the 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. 6 QUATTRO MANUAL 9.

Then, turn NOTE: Save the servo arms/horns; they will be reattached to the servos after installation. 8 QUATTRO MANUAL 10. FLIGHT PACK INSTALLATION Flight pack installation varies greatly from one model to another. For your convenience, we have included the photograph below outlining a typical flight pack installation in a standard 4-channel trainer type model airplane. Fuselage Servo, Receiver, Battery Installation Aileron (Wing) Servo Installation 10.1 INSTALLATION SUGGESTIONS It is important to correctly install the radio system in your model. Please read and carefully follow the suggestions listed below:
4. With the servo at neutral, install the required servo arm/horn exactly 90 to the servo case as shown in the diagram below. 5. Before installing the servo output arms, make 1. For added protection, wrap the receiver and the sure the servo is in its neutral position. receiver NiCad in foam rubber that is at least 1/4" thick. 2. Run the receiver antenna through the fuselage and make sure it is fully extended. Never cut or bundle your receiver antenna this 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). See Section 9.3. 6. 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. 7. 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 the switch operates freely and is capable of traveling its full distance. Servo Horn Control Rod 90 with Servo at Neutral/Center Position QUATTRO MANUAL 9 10.2 SERVO REVERSING After radio installation, it is imperative that the proper servo/control system direction be established. Servo reversing allows you to alter the direction of the servo/control surface movement to match the direction of the transmitter stick. Please refer to the chart in the following section below to determine the proper control surface direction. 10.3 SETTING REVERSING SWITCHES 1. Connect all control linkages and check to see 3. Using the Servo Reversing Switches located that all servos move freely. 2. While standing directly behind the airplane, go through the steps shown in the charts below to check proper direction of the control surface. behind the Transmitter Battery Pack, adjust the direction of each servo for proper operation.

Please refer to your aircrafts instruction manual for suggested travel limits. It is possible to increase/decrease the amount that your control surface moves at full stick deflection by mechanical adjustments. position, the servo itself then becomes stalled, unable to reach its full deflection. This condition is both harmful to your control linkage and to your servo. This stalled condition will also force the servo to drain power more quickly from your flight pack battery, thereby reducing your usable flying time. Fortunately, servo stalling is usually easy to detect by either a buzzing or humming sound which comes from the stalled servo. It is imperative that the servo does not attempt to push/pull the control surface past its mechanical limits. This condition is called binding. When a servo moves a control surface into a binding The following diagram is designed to help clarify how to increase or decrease control surface travel mechanically to eliminate control surface binding and servo stalling. Figure 1 Normal (Linear) Linkage Set Up Figure 2 Increased Control Surface Movement Figure 3 Reduced Control Surface Movement Control Rod Control Rod Control Rod Servo Arm Control Surface Arm (Horn) Servo Arm Control Surface Arm (Horn) Servo Arm Control Surface Arm (Horn) To increase control surface travel, select a linkage attachment point further outward on the servo arm or further inward on the control horn closer to the control surface (Figure 2). To reduce control surface travel, select the linkage attachment point close to the center of the servo area or further out on the control horn on the control surface (Figure 3). Quite simply, by moving the control rod in on the servo arm/wheel, control surface travel will be reduced, and by moving the control rod out on the servo arm, the control surface travel will be increased. The opposite holds true for the control surface arm (horn) as well. You may also use any combination of these positions to achieve proper control surface/servo travel. NOTE: Once the appropriate servo arm/wheel and control rod location has been established, secure the servo arm to the servo output shaft using the original servo horn screw. QUATTRO MANUAL 11 11. PRE-FLIGHT INFORMATION 11.1 QUATTRO TRAINER SYSTEM The Quattro features a built-in trainer system. The transmitter can be used as either a master (trainer) or as a slave (trainee). The Quattro is compatible with all other current PPM selectable (FM) J-line or JR radios that have built-in trainer systems. An optional trainer cord is needed (JRPA130).

Turn ON the master transmitter. NOTE: The slave radio must be left OFF. 4. Test all the control functions on your aircraft Special Note to Beginners: We strongly suggest that you seek the help of an experienced model airplane pilot prior to flying your new model. with the master radio. 11.3 RANGE TESTING YOUR MODEL We suggest that before the initial flight of your model, you first perform a ground range test to ensure that the transmitting/receiving abilities of your Quattro perform properly. Conduct the range test as follows:
Do not extend the transmitter antenna at this time. Turn your Quattro transmitter ON. Next, turn the model switch ON. Slowly walk away from the model while moving the control surfaces. The system should function properly to a distance of approximately 60-65 feet. NOTE: If your test falls short of the described range, confirm that your NiCad batteries are fully charged. If this situation remains unchanged, please contact the Horizon Service Center (address and phone number at the back of this manual) before attempting to fly your model. 12 QUATTRO MANUAL 12. GENERAL NOTES Radio controlled models are a great source of pleasure. 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 experience pilot or your local hobby shop. Safety Dos and Donts 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 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 PCM only 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. 13. DAILY FLIGHT CHECKS 1. Check the battery voltage on both the transmitter and the receiver battery packs. Dont 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 the receiver battery, be sure that you have polarities correct on your expanded scale voltmeter (optional). 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 the following ground range check before each days flying session:
Do not extend the transmitter antenna at this 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 60-75 feet. 5. Ensure that all trim levers are in the proper location. 6. Check to be sure that all servo pigtails and switch harness plugs are secure in the receiver. Also, make sure that the switch harness moves completely in both directions. QUATTRO MANUAL 13 14.
