8. Use epoxy to glue the nylon wing dowels into the
holes in the LE of the wing. The dowels should protrude
beyond the LE of the wing 1/2" [13mm].
INSTALL THE RETRACTS
❏
1. Use a 2mm hex wrench to remove the four set
screws (two per side) in the retract pivot. The fi rst set
on each side secures the landing gear wire in the
retract pivot. The second set screw on each side
locks the fi rst set screw in the retract pivot. Apply a
drop of threadlocker to the threads of the set screws.
Reinstall the set screws making sure that they tighten
on the fl ats on the landing gear wires. Be sure to
assemble a left and right retract.
❏
2. Remove the 3mm set screws from the axles.
Apply a drop of threadlocker to the set screws and
reinstall them in the axles. Slide the axles onto the
landing gear wires tightening the set screws on the
fl at spots at the end of the wires. Note the direction of
the axles.
❏
3. Apply a drop of threadlocker to the threads of a
6-32 x 1/4" [6.4mm] socket head bolt. Install the bolt in
a 4mm wheel collar. Slide the wheel collar onto the axle
and tighten the 6-32 bolt. Slide a 3-1/4" [82mm] foam
wheel on the axle and secure the wheel with a second
wheel collar. Make sure the wheel turns freely.
❏
4. Insert the retracts in the retract openings in the
wing. Adjust the position of the retracts so that the
retract body is centered on the mounting rails. Adjust
the position of the axle on the landing gear wire so
that the wheel is centered in the wheel well.
❏
5. On the retract mounting rails, mark the four
retract mounting holes. Remove the retracts and drill
a 7/64" [2.7mm] pilot hole at each mark.
❏
6. In one end of a 1/16" x 12" [1.6 x 12.7mm] wire
pushrod make a Z-bend. Insert the Z-bend in the
nylon horn on the retract.
