Know Your Frequency
Perform a Range Check
CAUTION: The transmitter used to control your plane transmits signalson one
of several frequencies that are available. To find out your frequency (or “channel”),
look on the transmitter, If your “channel” happens to be the same as another model
that is being flown nearby (even within a few miles), one or both models will crash.
Know your frequency and be aware of the frequency of other models that are
flying nearby-especially if you are flying at a radio control flying site. All flying sites
have some sort of frequency control system to avoid this kind of interference , so
learn how to use their frequency control system. Never turn on your transmitter
until you are certain that you will be the only one operating on your frequency.
As a precaution, an operational ground range test should be performed before the
first flight each time out. performing a range test is a good way to detect problems that
could cause loss of control such as low batteries defective or damaged radio
components or radio interference. This usually requires an assistant and should be
done at actual flying site you will be using.
First turn on the transmitter. Then, install the fully charged battery into the fuselage
and hold it in place with the hook-and-loop strap. Connect the battery and install
the hatch.
Remember, use care not to “bump” the throttle stick. Otherwise, the prope-
ller will turn, possibly causing damage or injury.
With the antenna on the transmitter collapsed (not extended ), begin walking
away from the model operating the controls in a predictable pattern (for example: Up,
then down elevator. Right, then left aileron. Right, then left rudder). While moving
the control surfaces, also vary motor rpm.
Have your assistant alert you if the controls fail to respond or if they move suddenly
or erratically. You should be able to maintain control up to a distance of approxi-
mately100’ [30m].
