Control Throws; Recommended Center Of Gravity (Cg) - Hangar 9 Tango 40 ARF Assembly Manual

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 1
Aileron High Rate 2
Note: Aileron throw is measured at the
inboard trailing edge of the aileron.
Elevator Low Rate 1
Elevator High Rate 2
Note: Elevator throw is measured at the
inboard trailing edge of the elevator.

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 Tango 40 is 4- to 5-inches (102–127mm) behind
the leading edge of the wing against the fuselage. Mark
the location of the CG on the bottom of the wing
as shown. Turn the airframe upright to balance. The
Tango 40 must be upright when measuring the CG or it
will not balance correctly. 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.

Once the control throws have been set, slide the clevis
retainers over the clevis to prevent them from opening
during flight.
