Your model was designed to use three or four- channel

radio control equipment. In flight, the model is primarily controlled
by using the ailerons and elevator (see sketch at left). One radio
channel controls the ailerons. This is the primary turn control - it
rolls the model. Another channel operates the elevator which con-
trols pitch (climbing, level flight and descent). The third channel is
for the engine throttle and controls the engine speed. A fourth
channel is used for rudder which assists the ailerons for turning.
The new R/C flyer will probably only use the rudder for steering the
model on the ground. Note: for three-channel flying, ailerons are
not used and the rudder becomes the primary turn control.

Radio sets are battery powered with either dry cells

(small flashlight type batteries) or more reliable rechargeable
nickel-cadmium batteries (ni- cads). Sets powered with ni-cads
come equipped with a recharging unit, and are more expensive
than dry-cells sets. However, if you intend to do a lot of flying, the
cost of routinely replacing worn out dry cell batteries will be much
greater than the higher initial cost of a re-chargeable ni-cad radio
system; something to consider. Many of the radio systems now
available feature “servo reversing” switches which allow you to
reverse the response of the servo. This feature simplifies radio
installation and is a worthwhile consideration when selecting a
radio system. You may find radios with more sophisticated fea-
tures such as dual rates, exponential and control mixing, etc.
These features are not needed for general sport flying, and are
typically used my more advanced flyers.

When selecting a radio, remember that there are many

radio frequencies available. Not all of these frequencies can be
legally used to operate model airplanes. Tell your dealer that you
want a radio with a model “Airplane” frequency.

WARNING:

Per the Federal Communications Commission there

is only one group of frequencies designated for radio control air-
craft use. According to the law, it is your responsibility to use the
designated aircraft frequencies to operate your model airplane.
