Great Planes PT-E Trainer Electric Kit - GPMA0110 - Manual (Page 20)

D 6. Remove the nut and the washers from the toggle
switch. Insert the threaded barrel of the toggle
switch through the 1/4" hole in the fuse side, then
secure it with a nut on the outside.
D NOTE: The toggle switch in the photo is shown
incorrectly. It should be rotated 180 degrees, as
it is shown on the plan, to operate correctly.
Correct operation of the toggle switch means
that pushing the switch forward is "on", and
pushing the switch backward is "off.
D 3. Insert the plastic outer pushrod sleeve through
the hole you previously drilled in F-2 and glue it
securely to F-2 with thin CA, followed by thick CA.
The tube should protrude only about 1/4" in front of
F-2.

(Not required for 2-channel operation)
D 4. Grasp the 1" threaded rod in the middle with a
pliers, and screw the nylon clevis onto one end and
the plastic pushrod onto the other end.
NOTE: If you wish to fly the PT- Electric with a 2-
channel radio (rudder and elevator control only), just
wrap masking tape around the micro switch to hold
it in the "closed" position, and proceed to the next
section.
D 1. You'll need the following parts: 4-1/4" long plastic
outer pushrod sleeve, 6-3/8" long inner plastic
pushrod, 2-56 threaded rod 1" long, and a nylon
clevis.

D 2. Roughen the outside surface of the plastic pushrod
sleeve with 100 grit sandpaper (so the glue will stick
better).
D 5. Insert the plastic inner pushrod into the outer
sleeve and attach the nylon clevis to the servo arm.
(You may have to drill the servo arm with a 5/64"
drill bit to fit the clevis pin).
D 6. Temporarily hook up your radio system. (Be sure
to read the radio instruction manual regarding
proper hookup and battery charging proce-
dures).
D 7. Study the fuse plan side view and note the position
of the micro switch. Now hold the micro switch
against the fuse side in this approximate position.
Operate the throttle servo and observe how the push
rod contacts the micro switch. Move the micro
switch around until the pushrod "clicks" the micro
switch only when the throttle stick is pushed almost
fully forward.
