13...Install the servos into the plywood servo tray. The servo
output arms should be at the forward end of the servo. Use
care to not move the servo output arms from their neutral
position.
Feed the wire pushrods into the fuselage from the rear exits.
The “Z” bends should be at the front and attached to the
output arms. Tighten the servo arm screws.
14...Slide the plastic Control Horn Clevis Retainer onto the
rudder pushrod wire. Snap the plastic Control Horn Clevis
into the rudder control horn. Then with the rudder servo in
neutral position, hold the rudder in neutral while you lay the
threaded end of the pushrod wire into the groove in the
plastic clevis. Push the wire down firmly into the groove.
15...Slide the Clevis Retainer onto the Clevis, trapping the
pushrod wire in place. Check to be sure that the rudder is still
in the neutral position. If it is not, unsnap the clevis from the
control horn and adjust the pushrod length by screwing the
clevis in or out on the threads.
Now repeat this process to install the clevis onto the elevator
pushrod.

To operate the system, first turn the transmitter
on and place the throttle stick in the low
position. Now plug the airborne battery into
the input side of the electronic speed control
and the system is operational (see NOTICE:
below). Test the system by moving the right
stick on the transmitter, which should move the
rudder and elevator servos.
Initially, the motor is not armed and will not
function when you move the throttle stick. To
arm the motor you must move the throttle stick
to the high position and hold it there for
several seconds. Then move the throttle stick to
the low position and hold it there for several
seconds. The motor is now armed. Moving the
throttle stick now will activate the motor. Make
sure everything is functioning properly on your workbench BEFORE you install any of the components into the model. While the
radio is on make sure that the rudder & elevator trim levers on the transmitter are in the centered position. This will make sure that
the servos are centered. Unplug the battery from the electronic speed control to turn the system off.
NOTICE: The HiTEC FEATHER PACK airborne package we used came with a small MICRO SWITCH HARNESS. We elected not
to use the swith harness to save weight. It is easy to turn the radio system on and off simply by plugging in and unplugging the bat-
tery pack.
