Adjusting The Engine; Control Throws - Hangar 9 P-40 Warhawk 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.

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.
