Great Planes Super Sportster 40 MkII ARF - GPMA1042 - Manual (Page 16)

❏
2. Use coarse sandpaper to roughen the 3/16" x 12" [4.8
x 300mm] guide tube so glue will adhere to it, then guide it
through the hole in the firewall for the throttle pushrod.
❏
3. Thread a nylon clevis twenty full turns onto a 17-1/2"
[445mm] threaded pushrod wire. Slip a silicone retainer over
the clevis. Insert the pushrod into the throttle guide tube.
Bend the pushrod as necessary, then connect the clevis to
the carb arm on the engine.
❏
4. Screw a nylon clevis twenty full turns onto the end of
a 36" [910mm] wire pushrod. Slip a silicone retainer over the
clevis, then connect the clevis to the second-from-the-outer
hole of a nylon control horn. Cut 10" [250mm] from the other
end of the pushrod. Prepare another pushrod the same way.
❏
5. Slide the pushrods through the guide tubes. Position
the control horn coming out of the right side of the fuselage
on the elevator and position the control horn coming out of
the left side of the fuselage on the rudder as shown in the
photo. The holes in the horns should be over the hinge gap.
If necessary, small bends may be made in the pushrods to
get the horns to rest on the control surfaces.
❏
6. Drill 3/32" [2.4mm] holes through the elevator and
rudder for mounting the control horns with 2-56 x 1/2"
[13mm] screws, then mount the control horns using the
screws and the nylon backing plates on the other side.
Now that all the pushrods are installed, the servos can be
mounted…
Refer to this photo to mount the servos.
❏
7. Place the servos in the servo tray. Cut off the extra arms
to make one-arm servo arms. Enlarge the holes in only the
elevator and rudder servos with a Hobbico Servo Horn Drill
(or a #48 or 5/64" [2mm] drill bit). Fit the servo arms on the
servos as shown in the photo.
❏
8. If the guide tubes are too close to the servos, trim the
tubes as necessary.
❏
9. Holding the elevator and rudder centered, mark the
elevator and rudder pushrods with a felt-tip pen where they
cross the holes in the servo arms. Use pliers to make a 90-
degree bend at the marks. Temporarily fit a nylon Faslink to
each pushrod, then cut the wire with 1/16" [1.5mm]
protruding from the Faslink.
❏
10. Connect the elevator and rudder pushrods to the servo
arms with the Faslinks.
