2. Following the manufacturer's recommendations,
install and connect three servos, the receiver, the switch
and the battery as shown in the photo. We added a Great
Planes Switch Mount & Charge Jack (#GPMM1000, not
included) for convenience and ease of use at the field. It is
installed in the side of the fuselage opposite the engine
exhaust. Center the elevator and rudder trims on the
transmitter. Turn the radio on and center the servo arms.
3. Thread a 4-40 torque rod horn onto the aileron
torque rods until they are 1" [25.4mm] above the surface of
the wing. Cut off any excess torque rod that extends past
the torque rod horn.
4. Cut a notch in the aileron servo tray so the wire from
the servo can pass through. Install the aileron servo with
the output arm towards the trailing edge of the wing.
Connect it to the receiver, turn on the radio, then center the
servo horn.
5. Thread a nylon clevis 13 revolutions onto the
threaded end of both 6" [152mm] wire pushrods. Install a
silicone retainer onto each clevis. Connect each clevis to
its torque rod horn. Center the ailerons, then mark the
pushrods at the point where they meet the holes on the
servo arm. Make a 90 degree bend down in the wires at
this mark.
6. Cut off the excess wire 3/8" [9.5] below the bend.
Enlarge the servo horn holes with a 5/64" [2mm] drill bit. Insert
the bent wire pushrods into the servo horn from the upper
side, then secure them with Nylon FasLink
Install the Pushrods & Control Horns
1. Thread a nylon clevis 13 revolutions onto the
threaded end of both 36" [914mm] wire pushrods. Install
a silicone retainer onto each clevis. Trim the backing plate
from both nylon control horns, then clip the clevis to the
top hole of the horns. Clevis placement will be adjusted on
the control horn for proper control throw later .
