The amount of control throw should be adjusted as closely
as possible using mechanical means, rather than making
large changes electronically at the radio. By moving
the position of the clevis at the control horn toward the
outermost hole, you will decrease the amount of control
throw of the control surface. Moving it toward the control
surface will increase the amount of throw. Moving the
pushrod wire at the servo arm will have the opposite
effect: Moving it closer to center will decrease throw,
and away from center will increase throw. Work with a
combination of the two to achieve the closest or exact
control throws listed.

spin maneuvers.

An important part of preparing the aircraft for flight is
properly balancing the model. This is especially important
when various engines are mounted.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) range for the
Piper J-3 Cub is 3

" (82.5mm) behind the leading edge
of the wing against the fuselage. It is suggested to start at
the forward end of the range until comfortable with the
flight characteristics of your aircraft. If necessary, move
the battery pack or add weight to either the nose or the
tail until the correct balance is achieved. Stick-on
weights are available at your local hobby shop and work
well for this purpose.
