User's Manual

Note: We want a good range check to be at least 75 feet or so.
- When you are ready to fly your model, position the throttle stick or switch to its low speed or off
position.
Then, you may turn on the transmitter power followed by the receiver power.
- When you have finished flying, turn off the receiver power first then turn off the transmitter power.
If you do not follow these procedures, the receiver has no information to hold the servos steady and
you may damage your servos or control surfaces or flood your motor.
- In case of electric-powered models the motor may unexpectedly turn on and cause a severe injury if
the transmitter is switched off before the receiver.
- Before starting the engine, power up the transmitter and receiver, and check to be sure that the
servos follow the movement of the sticks.
- If a servo operates abnormally, don't attempt to fly until you determine the cause of the problem.
- Before starting the engine, be sure to check that the transmitter model memory is correct for the
chosen model.
- While you're getting ready to fly, if you place your transmitter on the ground, be sure that the wind
won't tip it over.
- If it is knocked over, the throttle stick may accidentally get moved causing the engine to race
unexpectedly, causing damage or injury to anyone nearby.
- Finally, don't fly in the rain! Water or moisture may enter the transmitter through the antenna or stick
openings and cause erratic operation or loss of control.
If you must fly in wet weather during a contest, be sure to protect your transmitter with a plastic bag or
waterproof barrier.
