To ensure the safety of yourself and others, please observe the
following precautions:
Ni-cd Battery
Charge the Batteries! Don't forget to recharge the batteries before each flying
session. Plug in the charger that comes in this system and hook up the transmitter
and airborne batteries the day before a planned flying session. A low battery will
soon die causing loss of control and a crash. When you begin your flying session,
reset your 8Usuper's built-in timer, and during the session pay attention to the
duration of usage.
Quit flying long before your batteries become low on charge. On-field
charging of your batteries with a field charger is not recommended. Overcharging
the Ni-Cd batteries with a fast-charger may cause overheating and a premature failure.
Flying field
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 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 their vicinity.
If you must fly away from a club field, be sure there are no other modelers flying
within a two-mile range, or you may lose control of your aircraft.
On the flying field
Before flying, be sure that the frequency you intend to fly with is not in use,
and secure any frequency control device (pin, tag, etc.) for that frequency before
turning on your transmitter. Never believe that it's possible to fly two or more
models on the same frequency at the same time. Even though there are
different types of modulation (AM, FM, PCM), only one model may be flown on
a single frequency.
To prevent possible damage to your radio gear, turn the power switches on and off in
the proper sequence, given below.
When you are ready to fly your model, move the throttle stick to the low
speed position, or do whatever is necessary to command your motor NOT to run.
Then, you may turn on the transmitter power followed by the receiver power.
When you have finished flying, begin by turning off the receiver power, then
turn off the transmitter power. If you do not follow these procedures, you may
damage your servos or control surfaces, flood your motor, or in the case of electric-
powered models, the motor may unexpectedly turn on and cause a severe injury.
We recommend that you range-check your system before each flying session.
Before starting the engine, fully extend the transmitter antenna, power up
the transmitter and receiver, and check to be sure that the servos follow the
