If it is knocked over, the throttle stick may be accidentally moved, causing the engine to speed up. Also, damage to your transmitter may occur. Other than 2.4GHz system: Before operating, be sure to extend the transmitter antenna to its full length, collapsed antenna will reduce your flying range and cause a loss of control.It is a good idea to avoid pointing the transmitter antenna directly at the model, since the signal is weakest in that direction. In order to maintain complete control of your aircraft it is important that it remains visible at all times . Flying behind large objects such as buildings, grain bins, etc. are not suggested. Doing so may result in the reduction of the quality of the radio frequency link to the model. 2.4GHz system: Do not grasp the transmitter modules antenna during flight.Doing so may degrade the quality of the radio frequency transmission. 2.4GHz system: As with all radio frequency transmissions, the strongest area of signal transmission is from the sides of the 8CH transmitter module's antenna. As such, the antenna should not be pointed directly at the model.If your flying style creates this situation,easily move the antenna to correct this situation. Warning!!!
Please don't fly in the rain! Water or moisture may enter the transmitter internal through gaps in the antenna or joystick flight and cause your flight to instability even out of control. If inevitable will fly in the wet weather (such as game), please be sure to use plastic bags or waterproof cloth to cover your transmitter, please don't flight if there is lightning.

4 1.2 T8FB remote control system 1.2.1 Transmitter 1) One two-way switch, one three-way switch, two VR switches, four trimmers, two sticks. 2) Defaulted MODE2, SwB control CH5, VrB control CH6, SwA control CH7, VrA control CH8. 3) Defaulted low battery alarm voltage is 11.1V, can setting in the T8FB configure software. 1.2.2 Receiver: R8EH R8EH: 8 channel receiver support S-BUS, PPM and PWM signal at the same time. 8 channel receiver R8EHsignal type: PWM&S-BUS&PPM R8EH Specification:
1. S-BUS/PPM/PWM Compatible with FUTABA S-BUS connection port, S-BUS, PPM and PWM signal are possible to use at the same time. PWM signal mode: Green LED, output 8 channel PWM signal. SBUS/PPM signal mode: Both red and green LED on, CH1 output S-BUS signal, CH2 output PPM signal, CH3 to CH8 output PWM signal at the same time. 2. Operating voltage: 4.8~10V. 3. Operating current: 19~25mA(input voltage 5V) 4. Size: 48.5*21*11mm 5. Weight: 7g 6. Section precision: 4096 1.2.3 Bind Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. 5 Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver is to be used with another transmitter. When you purchase another R8EH, this procedure is necessary; otherwise the receiver will not work. 1) Place the transmitter and the receiver close to each other within 1 meter. 2) Connect CH3(R8EH) to ESC. 3) Press and hold ID SET switch of the receiver one second, now the indicator LED will starting blinking. It will automatically find the nearest transmitter to bind. 4) Test with servo to make sure the binding is finished. 1.2.4 S-BUS, PPM and PPM signal change Short press the ID SET switch two times within 1 second, the signal is changed from normal PWM to S-BUS or PPM. The green LED indicates the normal PWM and red&green LED indicates S-BUS or PPM signal. 1.2.5 Transmitter calibration:
1. Press rudder trimmer left and turn on transmitter at the same time, red and green LED flashing. 1) End point calibration Push two sticks from the highest position to the lowest position, and then put sticks to the center position. (P1) P1 2) Center position calibration:
Put stick to the center position, press rudder trimmer right, and then red and green LED always on means sticks calibrate successful. 1.3 Guidelines to mount the servos, receiver and battery Make certain the alignment tab on the battery, switch and servo connectors is orient correctly and key into the corresponding notch in the receiver or connectors before plugging them in.When unplugging connectors, never pull on the wires. Always pull on the plastic connector instead. Receivers Antenna: In generally receivers antenna is longer than remote control,dont break or retract it,otherwise shorten the control distance.The antenna must be kept away from conductive materials,such as metal. Please make distance test before flying. If your aileron servos are too far away to plug into the receiver,use an aileron extension cord 6 to extend the length. Avoid plugging multiple extensions together to obtain your desired length. If the distance is greater than 50cm or high current draw servos are being used, use heavy servo extensions. Receiver Vibration and Waterproofing: the receiver contains precision electronic part.Be sure to avoid vibration,shock,and temperature extremes.For protection, wrap the receiver in foam rubber or other vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag and securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver,you may experience intermittent operation or a crash. If in doubt, please contact Radiolink after-sales or distributors for service. Always mount the servos with the supplied rubber grommets. Dont over tighten the screws. No part of the servo casing should contact the mounting rails, servo tray or any part of structure. Otherwise vibration will be transmitted to the servo causing damage of servo. Note the small numbers (1,2,3,4) molded into each arm on the servo arms. The number indicate how many degrees each arm is off from 90 degrees to correct for minute manufacturing deviations from servo to servo. To center the servos, connect them to receiver and turn on the transmitter and receiver. Center the trims on the transmitter, then find the arm that will be perpendicular to the push rod when placed on the servo. After the servos are installed, operate each servo over its full travel and check that the push rods and servo arms dont bind or contact each other. Also make sure the controls do not require excess force to operate. If there is an objectionable buzzing sound coming from a servo, there is probably too much resistance in the control. Find and correct the problem. Even there is no servo damage, excess battery drain will result. Use the mouthing plate from the receiver on/off switch as a template for the cutout and screw holes, mount the switch on the side of the fuselage opposite the engine exhaust, and where it wont be inadvertently turned on or off during handling or storage. Be certain the switch moves without restriction and snaps from ON to OFF, and that the cutout allows full motion 7 of the switch in both directions. When install the switch harness to the helicopter, please use the switch cover. Generally sandwich the frame between the switch and switch cover and securely tighten the screws. Different models might require different installations. If so, please follow the models instruction manual. To prevent the servo lead wires from being broken by vibration during flight, provide a slight amount of slack or extra so that the wire sticks out slightly and fasten it at suitable points. In addition, periodically check the wire during daily maintenance. Upgrade/firmware version change/parameter setting cable 1. Install the T8FB upgrade drive files first. 2.

Computer will read data from transmitter and show on the computer when click READ(red and green LED will quick flashing when reading). LOAD:
Load configured TXT files. UPDATE:
Write down the new data you want and then click UPDATE to change the defaulted parameter. T8FB will remember the new data you have write down(red and green LED will slowly flashing when updating). SAVE:
Save current setting to TXT files. PHASE:
Changes the direction an individual servo responds to a control stick motion. SUB-TRIM:
Makes small changes or corrections to the neutral position of each servo. Range is -120 to
+120, with 0 setting, the default, being no SUB-TRIM. We recommend that you center the digital trims before making SUB-TRIM changes, and that 14 you try to keep all of the SUB-TRIM values as small as possible. Otherwise, when the SUB-TRIM are large values, the servo's range of travel is restricted on one side. The recommended procedure is as follows:
Measure and record the desired surface position;
Zero out both the trims (TRIM RESET menu) and the SUB-TRIM (this menu);
Mount servo arms and linkages so that the control surfaces neutral is as correct as possible;
use a small amount of SUB-TRIM to make fine corrections. END POINT:
Sets the range of each channel(in percentage);
End Point of servo travel adjustment (END POINT, also called EPA) The most flexible version of travel adjustment is available. It independently adjusts each end of each individual servos travel, rather than one setting for the servo affecting both directions. Adjustability:
Can set each direction independently. Ranges from 0% (no servo movement at all) to 140%. Defaulted 96%. Reducing the percentage settings reduces the total servo throw in that direction. END POINT adjusts only the individual servo. It will have no effect on any other servo that is operated in conjunction with this servo via mix or preset programming such as FLAPERON, AILEVATOR, etc. This is so that each individual servo can be carefully fine-turn to avoid binding and other conflicts. To adjust the total travel of a function such as FLAPERON, make the adjustments in that function's controls. The higher the END POINT setting, the better position accuracy and the more servo power available at nearly any position (except if using digital servos). Higher END POINT values also mean longer travel time to reach the desired position, as you are utilizing more of the servo's total travel. (For example, using 50% END POINT would give you only half the steps of servo travel, meaning every click of trim has twice the effect and the servo gets there in half the time). END POINT(and moving the linkage) = torque, accuracy, but transit time to get there. END POINT (instead of adjusting linkages) = travel time, but torque, accuracy. FAIL SAFE:
F/S data,set responses in case of loss of signal or low Rx voltage(in percentage). Each channel can be set independently. The NOR (normal) setting holds the servo in its last commanded position. The F/S (Fail Safe) function moves each servo to a predetermined position. NOTE: the setting of the throttle's F/S also applies to the low battery voltage. The F/S is used in certain competitions to spin the aircraft to the ground prior to flying away and doing potential damage elsewhere. Conversely, may also be used to go to neutral on all servos, hopefully keeping the plane flying as long as possible. 0 means throttle at the lowest position, 50 at the center position. 15 AUX-CH:
Defines the relationship between the transmitter controls and the receiver output for channels 5-8. TX-ALARM:
Setting transmitter alarm voltage(defaulted 11.1 V). STK-MODE:
Change the mapping relation among sticks(MODE1 means throttle is the right stick; MODE2 means throttle is the left stick). 16
