Control Throws; Range Test Your Radio - Hangar 9 B25J Mitchell 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.
Elevator Low Rate
7 degrees, 3/8-inch or 8.5mm up/down
Elevator High Rate
13 degrees, 5/8-inch or 16mm up/down
Note: Elevator throw is measured
at inboard end of elevator.
Rudder Low Rate
10 degrees, 1/2-inch or 13mm right/left
Rudder High Rate
16 degrees, 13/16-inch or 21mm right/left
Note: Rudder throw is measured at
the widest part of the rudder.

Range Test Your Radio

Range check your radio system before each flying
session. This is accomplished by turning on your
transmitter with the antenna collapsed. Turn on the radio
in your airplane. With your airplane on the ground, you
should be able to walk 30 paces away from your airplane
and still have complete control of all functions. If not,
don't attempt to fly! Have your radio equipment checked
out by the manufacturer.
Aileron Low Rate
10 degrees, 3/8-inch or 9.5mm up/down
Aileron High Rate
15 degrees, 9/16-inch or 14mm up/down
Note: Aileron throw is measured
at inboard end of aileron.
Half Flap Position
20 degrees,1-inch or 26mm down
Full Flap Position
15
40 degrees, 1 / -inch or 49mm down
16
Note: Flap throw is measured at
end of flap against the fuselage.
Once the control throws have been set, slide the clevis
retainers over the clevis to prevent them from opening
during flight.
