2. Assemble the two fuselage sides with the former notches in the sides. Note that there are two sets of fuselage
sides. One set has all the notches to accept the formers in it and the other set is marked skins. Put the set
marked skins aside for use later. Also note that the sides are marked Left and Right. The two sides are
slightly different and must be used in their appropriately marked locations. They will set the thrust offset
in the firewall. Glue on the aft section of each fuselage side. Next, using the pinning holes at the front and
back of the 1/32” ply doublers, glue on the doublers using the following method. Place the fuselage side on
the pins and test fit the doublers by sliding it down the pins. Remove the doublers and flip it over. Apply a
liberal bead of thick CA to the following areas. All areas of the forward solid area (the area without the glue
port holes cut into it), along the wing saddle, at each former and all of the aft solid area. The area with the
holes cut in it will be glued later with thin CA. Now slide the doubler down the pins and press into contact
with the fuselage side. As soon as the two parts have fixed, remove the pins and apply pressure along the
entire doubler. Use a straight edge to apply pressure to the doubler and liberally apply thin CA through all
the glue portholes.
Some fuselage subassemblies. Note the
addition of 1/4 X 1/8 hardwood behind the
screws on the servo tray. Pinning holes in
the wing bolt plate provide perfect align-
ment when laminating the two parts. Note
that the #1/4-20 blind nuts have been
trimmed.
Here the fuselage construction has begun,
showing the laminated firewall, lami-
nated F2& F2-A as well as the tank floor.
These components will set the angle of
the firewall at 3-1/2° of right thrust. Add
triangle stock for additional strength.
Again the use of pinning holes provided
in the parts make accurate alignment of
the fuselage doublers fool proof. The
holes in the 1/32” doubler are for apply-
ing glue as well as lightening.

3. Lay one fuselage side on the building board and using Epoxy, glue in F4-A. Use a square to assure it is at
90º to the side.
□
4. Cut a piece of scrap stock 3-1/2” long to be used as a tail spreader in the next step. Apply Epoxy to the
remaining side of F4-A and install the second fuselage side. Use the spreader stick in the tail section to keep
the fuselage sides parallel until the Epoxy has cured. Also use a square to assure that both fuselage sides are
parallel at the elevator saddle.

5. Assemble the laminated wing bolt plate from one 1/4” lite ply and one 1/16” AC ply part. Press in the #1/4-
20 blind nuts, the nut flanges will require trimming.
□
6. Now install Former F-5, the wing bolt plate assembly and the servo tray with Epoxy. Note that all these
parts interface with each other.
□
7. Install F-6, F-7 & F-8 and the tail post (TP); note that the tail post is recessed 1/8” to leave room for the
vertical fin post.
□
8. Install F-4 with Epoxy.
□
9. Install the F-3 assembly with Epoxy.
□
10. Install the firewall assembly and the tank floor with Epoxy. After curing, add 3/8” triangle stock along both
sides and the firewall as well as along the tank floor and firewall.
□
11. Assemble and install the hatch hold down block (HH) and glue to F-5A.
