Adjusting The Engine; Control Throws; Recommended Cg - Hangar 9 Twist 3D .40 Assembly Manual

Adjusting the Engine

Step 1
Completely read the instructions included with your
engine and follow the recommended break-in
procedure.
Step 2
At the field, adjust the engine to a slightly rich
setting at full throttle and adjust the idle and low-
speed needle so that a consistent idle is achieved.

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.
Note: Aircraft is being tested. The correct
throws and center of gravity will be added
during layout.

Recommended CG

An important part of preparing the aircraft for flight
is properly balancing the model. This is especially
important when various engines are mounted.

Step 3
Before you fly, be sure that your engine idles reliably,
transitions and runs at all throttle settings. Only
when this is achieved should any plane be
considered ready for flight.

Elevator 1" (14°) up

Note: Control throws are measured at the
widest part of the elevator, rudder, and aileron
unless noted otherwise.
Use the following throws for 3D aerobatics:
Aileron 2 1 / " (35°) up

Elevator 2 3 / " (35°) up

Rudder 2 1 / " (28°) right

Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) range for
the Twist™ is 4"–5" 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.
