7. Drill through only one wing bolt plate, the

top sheeting

and the wing bolt block on one side of

t h e w i n g with a # 7 drill. K e e p t h e drill bit
perpendicular to the wing bolt plate as you drill

the head of the wing bolt will rest flat.

Remove the wing and tap threads into the

wing bolt block with

a 1/4-20 tap. Enlarge the hole

in the wing bolt plate and the top sheeting with

round file or a 1 7 / 6 4 drill. Replace the wing on the
fuselage and bolt it down with the one 1/4" nylon
wing bolt.

Replace the #7

drill bit in your drill. Repeat

steps

5, 6, 7 and 8.

10. Bolt the wing to your fuselage and leave the

wing bolts barely snug. Realign the wing.

11. Drill 1/4" holes through the 1/8" x 1" x 2"

plywood wing dowel plates. Slightly enlarge the

holes with a round file or a piece of sandpaper

wrapped around something round such as

a pen or

a piece of brass tube. This will allow you to plug the
wing into the fuselage without too much resistance.

12. Spread a thin film of 30-minute epoxy on one

side of both wing dowel plates and fit them over the

dowels protruding through former F2D inside the
fuse. Accurately mark the location of the plates
on F2D.

13. Remove the wing. Clamp the wing dowel

plates to F2D with C-clamps. Wipe excess epoxy

from the holes if any is present.

SHEET THE FORWARD DECK AND

BOTTOM

1. Assemble your fuel tank. Position the tank

floor and the tank in the fuselage and determine

where to drill the holes for the fuel lines. Drill the
holes with

a 1 / 4 drill (or 15/64" drill for a better fit).

2. Remove the tank and tank floor. Position the

die-cut 1/8" plywood cabin crutch

the fuse

main side stringers

so the aft edge contacts former

F7A. Position the die-cut

1/8"

plywood former F I A

on the fuse main side stringer

so it contacts the

crutch. Glue F1A to the side stringers only.

Remove the crutch.

Cut the stringers from pieces of leftover 3/16"

x 3/16" balsa to fit from F1A to the firewall. Glue
the stringers in position while using

a 90 degree

triangle to hold F I A perpendicular to the top of the
stringers.

4. Place 1/4" foam rubber on the tank floor. Test

fit your fuel tank with #32 rubber bands included
with this kit. Note: Rubber bands deteriorate over
time,

so you should replace them at least once a

year.

5. Sheet the forward

fuse

deck with leftover

3/32" balsa. After you glue the sheeting in position,
sand the front even with the firewall. Sand the back

even with F l A , but do not sand the rest of the
sheeting until you fit the cabin.
