BUILDING
INSTRUCTIONS

Before starting to build this kit, we
urge you to read through these
instructions.  They contain some
important building sequences as well
as instructions and warnings con-
cerning the assembly and use of the
model.
We expect that you have some build-
ing experience to take on this model.
This means, every minute detail is not
covered.  This is not a basic trainer.
The instructions together with the
simplicity of this kit will allow you to
produce a first class Ultimate .

BUILDING SUPPLIES NEEDED
Hobby knife w/ #11 blade
Thin Zap CA
30 Minute Z-poxy
Thread lock
Wire cutters
Pliers
Drill with bits: 1/8", 5/32", 5/64”

9/64”

Phillips and standard screwdriver
Small clamps
Masking tape
Tape measure
Washable marker
Paper towels
Rubbing alcohol

Begin construction by locating the

two 1/4-20 x 1” socket head bolt used
to bolt the bottom wing on. Put the
bottom wing in place and remove the
covering over the mount holes at the
trailing edge. Bolt the wing down.
Next locate the stabilizer and fit into
opening in fuselage. Check alignment
with wing, it should be parallel when
sighted from the rear. It should not
be necessary to remove any material
to achieve alignment, simply pushing
up or down on one tip should do it. If
necessary remove material from the
bottom of the stab saddle on one side
to achieve alignment.
