FRAME-UP THE FUSELAGE

D 1. Lay a piece of waxed paper over the FUSELAGE

TOP VIEW. Assemble but do not glue yet, the 1/8" Die-Cut
Plywood Front Fuselage Bottom (SPECF03) and the 3/32"
Die-Cut Balsa Rear Fuselage Bottom (SPRTF04) together
over the FUSELAGE TOP VIEW on the plans. Make sure the

bottoms are aligned with the plan and that both pieces are
pushed firmly against the work surface to even up the bot-
toms. If the joint is a nice tight fit, apply thin CA to the joint.
If the joint is a little loose, take the bottoms apart, apply thick
CA and reassemble them.

Install former F4 and press the sides into place. Use rubber
bands near formers F4 and F5 to hold everything together and
apply thin C/A around formers F3, F4 and F5.

D 5. Align the fuselage sides with the fuselage bottom

between formers F3 and F5 and apply thin CA along the joint.

D 2. Trial fit all of the 1/8" Plywood Formers (except
FIB and F4) in their respective notches in the fuselage bottom
and sand them if needed to make them fit properly. NOTE:
make sure the indented "dots" on former F1A are facing
forward so you can see where to drill the motor mounting
holes later.

D 3. Align the fuselage sides with the fuselage bottom

and position the formers so they will key into the notches.

D 6. Pull the rear fuselage sides together and press the

sides firmly against former F6. A couple of C2 clamps can be
used to hold the tail of the fuselage together and a rubber band
will help around the former. Apply a couple drops of CA on
the back edge of the rear fuselage doubler and a bead of thin
CA along the bottom sheeting joints and around former F6.

Take your time applying the thin CA and be sure to gel the
bottom and the sides pressed together nicely. Thick CA
should then be added to these joints to add strength.

D 7. Pull the front fuselage sides together so the formers

will key into place and use a rubber band to hold them. Apply
thin CA along the fuselage bottom and the around the form-
ers.
