approximately 1 degree of toe-in. Securely tighten the
screw in the axle onto the strut, then partially loosen
and tighten again so the screw will mark the location
where it has bottomed out on the strut. This will identify
the precise location where a fl at spot is to be ground
into the strut.
❏
13. Remove the axle from the strut and remove the
retract from the wing. Grind a fl at spot into the strut at
the mark left by the screw in the previous step.
❏
14. Tighten the axle onto the strut. Mount the gear
to the rail. View the wheel to see if the alignment is
correct. If necessary, adjust the fl at spot until the wheel
is straight ahead, or has a small amount of toe-in.
❏
15. Once the wheel and axle are properly aligned,
add a drop of threadlocker to the threads on the axle
screw, then securely tighten the screw in the axle
locking the axle to the strut. Also use a
small drop
of threadlocker on the screw that secures the collar
mounting the wheel to the axle.
❏
16. For the fi nal time, remove the retract from the
wing. Cut two 15" [380mm] lines from the pneumatic
line included with your retracts. Guide one of the lines
through the hole in the side of the rib under the fl ap
servo hatch out through the hole in the back of the
retract cavity (top photo at left). Guide the other line
in through the hole in the front of the fl ap servo hatch
(middle photo at left) and out through the holes in
the sides of the ribs on the side of the retract cavity
(bottom photo at left). It can be a little tedious to get
the lines through all the ribs and passages, but a pair
of hemostats and a piece of leftover pushrod wire with
a small “L” bent on the end makes fi shing the air lines
through pretty easy.
❏
17. Connect the lines to the fi ttings on the air cylinder
on the retract. Using care not to kink or pinch the air
lines, mount the gear to the rails with all four screws.
Snap the wheel cover into the rim on the outside of
the wheel as shown on page 14.
❏
18. Guide the other ends of the air lines through the
ribs in the center wing panel and out the hole in the top.
❏
19. Refering to the diagram on page 32, use the
T-fi ttings to connect both “up” lines and both “down”
lines to each other and connect another length of line
to each T-fi tting with a quick-disconnect.
