System Check and Operation
WARNING!
During all pre-fl ight preparations with the aircraft on the ground, make sure the throttle stick remains at the
minimum position and do not stand the Tx upright on the ground. Carefully lay the Tx on its back on the ground to prevent
it from falling over and possibly dislodging the throttle stick from the low position which would create a safety hazard. Make
sure all devices are properly mounted inside the model, and all wiring connections are solid to prevent them from easily
becoming dislodged during normal fl ight. It’s best to check the system with the propeller removed from the aircraft.
1. Once all connections are made, check the general operation of the radio and all other components before attempting
a fl ight.
2. Move the Tx throttle stick to the minimum (idle) position.
3. Turn on the Tx, and then the Rx.
4. Make sure all controls are operating in the proper direction. If any servo is turning in the wrong direction, change the
position of the reversing switch for that particular channel.
5. With both sticks at center position, move the trim levers for the aileron, elevator, and rudder channels so each respective
control surface is perfectly aligned with the main surface. For example: When the aileron trim lever is in the center
position, it’s best that the trailing edge of the aileron is aligned with the trailing edge of the wing itself (not above or below
the wing’s trailing edge).
6. Make sure that movements of the throttle stick result in an equal adjustment of the throttle in the model. Confi rm
that when the throttle stick is at maximum position the electronic speed control gives the appropriate indications
(LED and/or audible indicators) for full forward fl ight. And, when the throttle stick is at minimum position the electronic
speed control gives the appropriate indications for “off” or no motor rotation.
7. Anytime power is to be removed from the radio system, it’s important to shut down power in the aircraft
fi rst
.
Otherwise, the aircraft could become out of control and cause a safety hazard! Move the throttle stick and throttle
trim lever to minimum position to stop the glow engine or shut down the ESC. Once the propeller has stopped
rotating, shut off the ON/OFF power switch in the model, and disconnect the power battery from the ESC in electric
airplanes. Then turn off the power switch in the Tx.
AMA Safety Code (Excerpts)
Read and abide by the following excerpts from the Academy of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site or the Code that came with your AMA license.
GENERAL
1. I will not fly my model aircraft in sanctioned events, air shows,
or model flying demonstrations until it has been proven to
be airworthy by having been previously, successfully flight
tested.
2. I will not fly my model aircraft higher than approximately
400 feet within 3 miles of an airport without notifying the
airport operator. I will give right-of-way and avoid flying
in the proximity of full-scale aircraft. Where necessary,
an observer shall be utilized to supervise flying to avoid
having models fly in the proximity of full-scale aircraft.
3. Where established, I will abide by the safety rules for the
flying site I use, and I will not willfully and deliberately
fly my models in a careless, reckless and/or dangerous
manner.
5. I will not fly my model unless it is identified with my name
and address or AMA number, on or in the model.
Note:
This does not apply to models while being flown indoors.
7. I will not operate models with pyrotechnics (any device
that explodes, burns, or propels a projectile of any kind).
RADIO CONTROL
1. I will have completed a successful radio equipment ground
check before the first flight of a new or repaired model.
2. I will not fly my model aircraft in the presence of spectators
until I become a qualified flier, unless assisted by an
experienced helper.
3. At all flying sites a straight or curved line(s) must be
established in front of which all flying takes place with the
other side for spectators. Only personnel involved with
flying the aircraft are allowed at or in the front of the flight
line. Intentional flying behind the flight line is prohibited.
4. I will operate my model using only radio control frequencies
currently allowed by the Federal Communications Commission.
5.
I will not knowingly operate my model within three
miles of any pre-existing flying site except in
accordance with the frequency sharing agreement
listed [in the complete AMA Safety Code].
9. Under no circumstances may a pilot or other person touch
a powered model in flight;
nor should any part of the
model other than the landing gear, intentionally touch
the ground, except while landing.
