- Before you fly, perform a range check to confirm your radio system is responding correctly.
- To do a range check, power-up the aircraft and either ask a friend to help hold the aircraft or secure it somehow.
- Walk away from the aircraft until the aircraft "glitches" or you notice intermittent control loss.
- Walk back to the aircraft, pacing out the distance.
- 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.
- 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.
To ensure your own safety and the safety of others, please observe the following precautions:
We recommend that you fly at a recognized model airplane flying field.
You can find model clubs and fields by asking the nearest hobby dealer, or contacting the Academy of Model Aeronautics.
Always pay particular attention to the flying field's rules, as well as the presence and location of spectators, the wind direction, and any
obstacles on the field.
Be very careful flying in areas near power lines, tall buildings, or communication facilities as there may be radio interference in the vicinity.
Flying Safety
Flying field
Once you arrive at the flying field...
Note : We want a good range check to be at least 75 feet or so.
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. You may also flood the motor.
If you must fly in wet weather during a contest, be sure to protect your transmitter with a plastic
bag or waterproof barrier.
