TAIL CONSTRUCTION
1. ‡ Collect the following items.
(4) 3/16 x 3/8 x21” BALSA PT. #4853
(1) 1-3/4 SQ. x 21” BALSA PT. #4696
(3) 5/64 X 3/16 X 24” BALSA PT. #4698
(1) 1/2” SQ. x 8-1/4” BALSA PT. #4701
(1) D/C SHEET 4006 BALSA PT. #3606
containing:
Stab center platform
Stab leading edge joiner
Wing and tail gussets
Stab tips
Dorsal fin
(1) CENTERLINE MARKER PT. #1425
(7) SMALL FLEX-POINT HINGE PT. #1448
2. ‡ 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.
3. ‡ 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.
4. ‡ 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.
5. ‡ Glue the gussets in place and allow the entire
stab to dry thoroughly.
6. ‡ 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.
7. ‡ 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.
