Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 36)

RIGHT WRONG
D 3. Insert the pushrods into the tubes in the fuse, then
hold a Nylon Control Horn (NYLON002) in position on the
elevator (see sketch above for correct alignment). The
pushrod should not be bent and should slide easily in the
tube. Mark the location for the control horn screws on the
control surface. Drill the 3/32" screw holes through the
control surface, then prick a few pin holes into the wood
under the horn's location. Apply a drop or two of thin CA to
the pin holes to strengthen the wood. When cured, screw
the control horn in place with two 2-56 machine screws and
the backing plate. Repeat for the other control surface.
D 7. Repeat steps 5 and 6 for the rudder.
D 8. Hook up the throttle using a brass quick connector on
the servo horn. Make sure that the servo does not stall at
either end of its travel.
D 9. Plug an aileron extension into the receiver. Wrap your
receiver in a plastic bag, then wrap with foam rubber.
Secure the foam with a couple of rubber bands.
D 10. Glue a couple of leftover inner pushrod tubes to the
inside of the fuselage to use as antenna guides. Route the
antenna to the back of the radio compartment and out the
side of the fuselage. Anchor the antenna to the top of the
fin or to the tail gear wire with a rubber band. Do not trim
any excess wire from the antenna.
D 11. Mount the receiver switch and charging jack through
the fuselage on the right side of the fuse. We suggest using
a Great Planes Switch/Charging j a c k mount
(GPMM1000) because of its ease of installation and
tidy appearance.

(Refer to this photo when performing steps 5 thru 11)
D 4. Connect the receiver to the servos, switch and battery.
Turn on your transmitter and receiver, then center the
elevator and rudder servos. Be sure that the trim levers
are centered.
D 5. Center the elevator, then mark the pushrod where it
crosses the outside servo horn hole. Enlarge the servo
horn hole with a 5/64" drill bit.
D 6. Make a 90° bend in the pushrod on your mark. Then
insert it through the enlarged hole in the servo horn. Secure
it in place with a Nylon Faslink"" Pushrod Connector.
D 12. Plug the aileron servo into the receiver and center
the servo wheel. Slide a silicone retainer over the "hex" end
of a nylon clevis. Screw the clevis 14 turns onto the
threaded end of a 12" threaded wire. Trim the backing plate
from a nylon control horn, then clip the clevis to the third
hole from the top. Attach the control horn following the
same procedure used for installing the control horn on the
elevator. Center the aileron, then mark the pushrod where it
crosses the outside hole on the bellcrank. Make a 90° bend
in the pushrod on your mark. Then insert it through the hole
in the bellcrank. Secure it in place with a nylon Faslink
Pushrod Connector.
