The following section covers checking the amount of
throw each control surface has and how to increase or
decrease the amount of throw to match the throws listed
in the manual. In addition, you will check to make sure
each control surface is moving the correct direction when
operated from the transmitter.
After checking that the controls are moving in the correct
directions, the amount of the control movement must be
checked. By moving the control stick of each surface to its
full deflection, you will measure the amount the surface
has moved. By holding a ruler next to the surface and
establishing a reference, use the radio to make the surface
move and compare the measurements to those shown.
Hint: Place your ruler on a solid surface,
rather than hold it in the air, to take
measurements. This will guarantee your ruler
is not moving. If the ruler is moving you will
get inaccurate readings.
Note: If you have a fellow modeler with a
throw gauge that measures in degrees you can
borrow, the amounts are 12-degrees instead
of 1/2" for the elevator, 15-degrees instead of
7/8" for the rudder, and 10-degrees instead of
5/16" and 12-degrees instead of 3/8" for the
ailerons.
If the throws of the control surfaces are not moving the
amounts as described, you may need to change the Travel
Adjustment setting in the radio. To do so, read the section
in the radio manual on programming the radio.
