o o 9. Place a silicone clevis keeper on the pushrod. Then
place a FasLink ™ on the pushrod and remove the excess
pushrod with a rotary tool or diagonal pliers. Connect the
clevis to the control horn but do not snap in place. Connect
the bent end to the servo. Re-center the servo and adjust the
linkage by screwing the clevis either in or out until the aileron
is straight. Once the aileron is straight, snap the clevis in
place. Attach the FasLink
™ and slide the clevis keeper over
the clevis.
o 10. Repeat steps 1-9 for the other wing.
Join the Wing
o 1. Locate the two plywood wing joiners. Place them on
top of each other and test fit them into both wing halves. The
joiners should fit slightly loose to allow room for epoxy. If the
joiner is too snug, sand the joiners until they fit properly.
CONTROL HORNS
Please note that there are two different types of control
horns included. The control horns with the
larger holes
are meant for use with the Aileron pushrod clevises. The
control horns with the smaller holes are meant for use
with the Elevator and Rudder z-bends.
o o 5. Place the large hole aileron control horn on the
aileron, centering it on the mark you made in step 15. Use
a T-pin to mark the center of the holes. Use a 5/64" [2mm]
drill bit to drill into the aileron at the markings you just made.
Remove the mark you made on the aileron using some
denatured alcohol and a paper towel.
o o 6. Install the control horns using two 2 x 15mm [5/8"]
machine screws and the control horn back plates. The ends
of the screws can be cut flush with the back plates using
diagonal pliers or a rotary tool.
o o 7. Locate the 2 aileron pushrods, 2 nylon clevises, and
2 nylon FasLinks ™ . Screw the clevis onto the threaded end
of the pushrod by rotating the clevis 18 complete revolutions.
A Great Planes 4-in-1 Installation Tool (GPMR8035) makes
this task much easier.
o o 8. Place the clevis in the control horn without snapping
it shut. Center the aileron and mark the center of the servo
arm on the pushrod. Remove the clevis from the horn and
make a 90 degree bend in the pushrod at the mark. Using a
5/64" [2mm] drill bit, enlarge the outer servo horn hole.
