Top Wing Mounting
1. Locate the following items.
(4) cabane struts
(2) I-Struts
(1) Top Wing
(1) Bottom Wing
(1) Fuselage
(2) 1/4-20 x 2” wing bolts
(20)4-40x 5/8” socket head screws
(12) #4 flat washers
(8) #4 aircraft lock nuts
(8) I-Strut mounting lugs.
2 The cabane struts consist of two front
and two rear. The rear is slightly longer than the
front. The long ends with two holes go into the fuse-
lage. Slide the long leg in the hole and retain with
two 4-40 x 5/8” socket head screws. Use locktite to
make sure they do not vibrate out. Don’t completely
tighten the screws down until after you mount the top
wing. Leaving them loose until the top wing is in
place with the top of the cabane struts in the pre cut
notches, will give them room to move around a little
so they will line up perfectly. Tighten after the top
wing is in place.
4-40x5/8” socket head screws
4 places each side
3. The I strut mounts consist of 1/4” eyebolts that
screw into threaded blocks located in the top of
the bottom wing and the bottom of the top
wing.
