Great Planes ElectriCub Kit - GPMA0156 - Manual (Page 35)

❏ 4. Wrap the receiver and receiver battery (if used) in 1/4"
foam rubber.
❏ 5. Temporarily position the receiver and receiver battery
on the fuse bottom, in front of former F-3. Later, the receiver
battery may be moved forward or aft to balance the plane.
Plug the receiver battery into the receiver switch.
❏ 6. If you are installing one of the Great Planes motor
packages with the switch harness, mount the toggle switch
on the side of the fuselage.
❏ 7. Place the servo tray in the fuse. Do not attach it to the
servo tray rails. It will be attached later, allowing it to be
moved forward or aft to balance the plane. Plug the servos
and receiver switch into the receiver.
❏ 8. Cut and sand one of the servo control wheels to a
“cam” shape, similar to that shown on the plan. Clean the
micro switch and the top of the throttle servo case with
rubbing alcohol. Mount the micro switch to the top of the
throttle servo case with double-sided foam tape in such a
way that when you advance the transmitter throttle stick to
full throttle (pushed towards the top of the transmitter), the
servo wheel will activate the micro switch. When satisfied
with the operation of the switch, secure the switch to the
servo by wrapping with a narrow strip of strapping tape.
❏ 9. Charge the motor battery following the instructions
included with your charger.
❏ 10. Make sure the propeller is removed before testing
your motor system. Plug the motor battery into the switch
harness and activate the toggle switch. The motor should
begin running when the transmitter throttle stick is pushed
forward to full throttle and stop when the stick is pulled back.
With the toggle switch in the off position, you should not be
able to start the motor with the throttle stick. In order for
this safety feature to be effective, you should always
keep the toggle switch in the “off” position until you are
ready to fly.
NOTE: If you are using an electronic speed control,
install it at this time following the instructions provided
with the speed control. Test run the motor and speed
control to make sure it operates properly.
❏ 11. Unplug and remove the motor battery from the plane.
❏ 1. Separate the nylon control horns from the nut plates.
❏ 2. Lay the rudder on the fuse plan side view and determine
the location for the nylon control horn. While holding one of
the control horns in position on the left side of the rudder,
mark the mounting hole location on the rudder.
❏ 3. Drill a 3/32" diameter hole through the rudder at each mark.
❏ 4. Mount the control horn on the rudder with two 2-56 x
3/8" machine screws and the nylon nut plate.
❏ 5. Repeat the process to mount the control horn on the
bottom right side of the elevator.
❏ 6. Reinstall the elevator on the stabilizer, but do not glue
in the hinges.
❏ 7. Position the rudder on the fin and mark on the rudder
the location of the elevator joiner wire. Cut a notch in the LE
of the rudder to allow the elevator to move freely when the
rudder is installed on the fin.
❏ ❏ 1. Clean two of the 2-56 x 12" metal pushrods with
rubbing alcohol and a paper towel to remove any oily
protective coating.
❏ ❏ 2. Locate the two 1/4" x 1/4" x 13" balsa pushrod sticks
set aside when building the wing. Mark one of them “rudder,”
the other “elevator.”
❏ ❏ 3. Lay the elevator pushrod on the fuse top view. Note
that the front pushrod wire attaches to the top of the balsa
pushrod and the rear wire attaches to the right side. To
avoid confusion later, draw lines 1-3/8" long on the pushrod
where the wires will be attached.
