5. Note that the "N" strut has one leg that is slightly longer
than the other. The shorter leg goes toward the LE of the wing.
Attach the "N" strut to the brackets as shown with 4-40 x 3/8"
[9.5mm] Phillips head screws, #4 washers and a 4-40 nylon
lock nuts. The lock nuts are on the inside of the brackets.
❏
6. Go back and repeat steps 3 to 5 for the right wing panel.
❏
7. Locate the holes and cut the covering from the blind
nuts in the bottom of the top wing. Four holes are located in
the center of the wing and two are located at each end of
the wing halves.
❏
8. Mount the center cabanes with 4-40 x 1/2" [13mm]
SHCS, #4 flat washers and #4 lock washers in the top wing.
Be sure you mount the cabanes as shown.
❏
9. Install the four remaining brackets in the blind nuts at the
wing tips of the top wing using 4-40 x 1/2" [13mm] SHCS,
#4 flat washers and #4 lock washers. Do not fully tighten the
screws at this time.
❏
10. Place the top wing onto the "N" struts. Attach the top
wing to the "N" struts with 4-40 x 3/8" [9.5mm] Phillips head
screws, #4 washers and 4-40 nylon lock nuts the same way
you installed the strut to the lower brackets.
❏
11. Set the plane on its nose. Look at the relation of the
top wing to the bottom wing. Be sure the top wing is aligned
with the bottom wing. Adjust the top wing as needed. Then
carefully set the fuselage back on the landing gear.
❏
12. Without disturbing the top wing, verify that the lower
cabane mounting holes are positioned over the hardwood
blocks located in the fuselage, just under the covering. If
they are not, check to see if you have mounted the center
cabanes and "N" struts properly. Also look at the top and
bottom wings from the side. They should look almost
parallel. If it appears that the LE of the top wing is much
higher, the "N" struts are possibly backwards.
❏
13. Drill a 5/64" [2mm] hole through each of the four
mounting holes in the center cabanes. When you drill these
holes you must be drilling into the hardwood blocks located
in the fuselage, just under the covering.
❏
14. Install and then remove a #4 x 1/2" [13mm] sheet
metal screw and a #4 flat washer into each of the four holes.
Apply a couple drops of thin CA into each of the holes to
harden the threads. After the glue has cured, permanently
install the screws into the fuselage.
❏
15. Once you have the center cabanes installed, tighten the
socket head cap screws holding all the "N" strut brackets.
Connect the Aileron Joiner Rods
If you chose to utilize the two bottom wing servos to drive all
four ailerons, you will need to assemble the aileron joiner
rods so that the top ailerons can be driven with the bottom
ailerons. This can only be aligned correctly with BOTH
wings attached.
❏
1. Locate the two aileron joiner rods. Thread a 4-40 hex
nut and a 4-40 clevis with a silicone retainer onto each end
of the rod. Do not worry about length right now; this will be
adjusted when the rod is in place.
❏
2. Starting with the bottom ailerons, install a large nylon
control horn (not black) on the top TE of the aileron
centered directly behind the control horn. Use two #2 x 3/8"
[9.5mm] screws to secure the control horn. Remove the
screws and harden the holes using thin CA. Align the
control horn with the holes facing the rear of the plane as
shown and attach one end of the joiner rod to the outer hole
on the control horn.
