Section 11: Control Throws

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.
Aileron Low Rate 5/16-inch (8mm) up/down
Aileron High Rate 7/16-inch (11mm) up/down
Elevator Low Rate 3/16-inch (5mm) up/down
Elevator High Rate 5/16-inch (8mm) up/down
Rudder Low Rate 7/16-inch (11mm) right/left
Rudder High Rate 3/4-inch (19mm) right/left

Section 12: Recommended Center of Gravity (CG)

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) location
for the Sundowner 50 is 2
leading edge of the wing against the fuselage. 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 store and work
well for this purpose.

Note: All control throws are measured at
the widest point of the control surface.
Once the control throws have been set, slide the clevis
retainers over the clevis to prevent them from opening
during flight.
