Use the pull strings to run the servo wire and
24-inch extension {for the aileron} through
the wing. To use our control rods it will be
necessary to mount the servo with the servo
arm to the front. Be sure to follow the servo
manufactures instructions.
Drill a 1/8-inch hole in the aileron for the
control horn at the location shown.
SET-UP TIP
As with most planes configured like the
Monocoupe {Cub, Cessna, Porter} rudder is
required to keep the turns coordinated. This
is due to the adverse yaw created by the
ailerons. One way to reduce the need for
rudder is to use “aileron differential”. Put
simply, it means that the ailerons should go
up more then they go down. If you are using
a computer radio with separate channels for
each aileron, this can be done in the
programming. If you are using a “Y”
harness notice the angle that the servo arm
was installed in the photo. This will create
the differential needed. Always make sure
your servos are centered before installing
the
control rods.
Install a short control horn in the hole as
was done with the elevator. Install and
adjust the control rod/clevis assembly.
Power up and center the servo. Use a
straight edge on the bottom of the wing to set
the rod length.
Drill a 1/8-inch hole in line with the servo
center for the flap horn
Install a long control horn in the flap.
Notice the way the servo arm is positioned
on the servo, this will eliminate the need for
a reversed servo for one flap and insure they
return to the correct position.
