(1) CENTERLINE MARKER

(7) SMALL FLEX-POINT HINGE

PT. #1448

Lay the horizontal stabilizer portion of the plan

over the building board and cover with waxed

paper.

Buidling over the plan, carefully cut two 3/16 X

3/8” balsa sticks to form the stabilizer leading

edge. Make sure to exactly match the plan from

the center mark to the tips.

IMPORTANT! SAVE SCRAP MATERIAL FOR USE IN

CONSTRUCTING THE FUSELAGE.

Pin the pieces in position and glue at the cen-

ter joint.

Continue building the stab outline, pinning and

gluing the stab tips, the L.E. joiner, the center

platform, and additional 3/16 x 3/8” balsa sticks

in place as shown above.

Still working over the plan, and using the tech-

nique shown above, cut 5/64 x 3/16” balsa

sticks to form stab trussing. Trim carefully to

size, so that each truss fits in place without

forcing.

SAVE THE SCRAP MATERIAL!

When satisfied with the fit, glue in place.

Glue the gussets in place and allow the entire

stab to dry thoroughly.

Referring to the plan, mark the hinge locations

on the top of the trailing edge with a soft pen-

cil.

Using 3 or 4 drops of Super Jet™, tack-cement

the elevator to the stab.

Carefully transfer the hinge location marks

onto the elevator.

Again working over the plan, assemble the fin

and rudder in the same manner as the stabiliz-

er.

NOTE:

Since the rudder trailing edge. is tapered, it

should be shimmed with 1/16” balsa scrap

before gluing, so that it will be level.
