FLYING SAFETY
ｎWARNING
To ensure the safety of yourself and others, please observe the following precautions:
ｊ
Have regular maintenance performed. The transmitter should have regular checkups for wear and tear. We
recommend sending your system to the Futaba Service Center annually during your non-flying-season for a complete
checkup and service.
Batteries
ｊ
Charge the batteries! (See Charging the Ni-Cd batteries, for details.) Always recharge the receiver battery before each
flying session. A low battery will soon die potentially, causing loss of control and a crash. During the session pay attention
to the duration of usage.
ｊ
When your radio’s red LED become slow blinking, Low Battery Alarm, immediately land your model before losing
control. Always check your transmitter and receiver batteries prior to each flight.
Where to Fly
We recommend that you fly at a recognized model airplane flying field. You can find model clubs and fields by asking your
nearest hobby dealer or in the USA by contacting the Academy of Model Aeronautics.
You can also contact the national Academy of Model Aeronautics (AMA), which has more than 2,400 chartered clubs across
the country. Through any one of them, instructor training programs and insured newcomer training are available. Contact the
AMA at the address or toll-free phone number below.

ｊ
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 their vicinity.
At the flying field
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
1. Pull throttle stick to idle position, or otherwise disarm your motor/engine.
2. Turn on the transmitter power.
3. Turn on your receiver power.
4. Test all controls. If a servo operates abnormally, don’t attempt to fly until you determine the cause of the problem.
5. Start your engine.
6. Complete a full range check.
7. After flying, bring your throttle stick to idle position, or otherwise disarm your motor/engine.
9. Turn off receiver power.
10. Turn off transmitter power.
