D 48. Assemble the two pushrods by screwing a 1"
threaded rod into one end of each inner pushrod and then
screwing a nylon clevis onto each threaded rod. The rod
should thread into both the pushrod and the clevis at
least 1/4".
D 49. Attach the two long pushrods to the back two
servos as shown in the photo. Slide the outer pushrod
tubes over the inner pushrods until they are about 1/2"
from the servo end of the inner pushrod.
D 50. Press the balsa pushrod holder into the channel
about 6" in front of the fin and secure the pushrods to it
with the nylon tie wrap. It is a good idea to seal the balsa
pushrod holder with a light coat of epoxy, it will also
help hold it in place. Note: The rudder pushrod goes to
the left side of the fin and the elevator pushrod goes to
the right side (as viewed from the back).
D 51. Cut 2" off the threaded end of two of the 12" long
link rods. Use a pair of long nose pliers to bend the "Z"
in the unthreaded end of the 2" pieces.
D 52. Install the link rods in the 2nd hole from the outer
end of each control horn. With the control surfaces and
the servo horns in their neutral positions cut the inner
pushrod so the link rod will thread into the inner pushrod
approximately 2/3 of the way. Install the link rods into
the inner pushrods and adjust so that the control surfaces
are at neutral positions.
D 53. Wrap the receiver in at least 1/4" thick foam
rubber to protect it from vibration, hard landings, etc.
and use two rubber bands to hold the rubber in place.
Disconnect the rudder and elevator pushrods from the
servos and slide the pushrods under the rubber bands on
the top of the receiver. Position the receiver behind the
servos and reattach the clevises to the servo horns. The
switch can be taped (using double-sided tape
GPMQ4442) to the fuselage behind the receiver so it can
be reached from the back of the fuselage. The receiver
antenna should exit out the back of the fuselage without
encountering any other wires if possible. Use a small
rubber band to hold the antenna on a T-pin inserted in
the top of the fin.
