Assembly Instructions
Section 2— Fuselage
1) Remove the fuselage and using the hot knife, remove the covering from the areas to allow the dowels,
wing tube, aileron extensions and wing capture bolt to pass through.
2) Carefully remove the covering exposing the horizontal stabilizer slot.
3) Test fit the horizontal stabilizer making sure it is centered and aligned to the fuselage.
4) U lizing a Sharpie draw lines top and bo)om on the horizontal stab along the side of the fuselage and
then remove the stab from the fuselage.
5) Draw a line parallel to and approximately 1/8 of an inch inboard of the lines previously made.
6) Using your hot knife
CAREFULLY
cut along the new inboard lines and remove the covering being careful
not to cut into the shee ng.
7) Refit the horizontal stab checking it is centered and square. making sure that the horizontal stabilizer is
aligned at right angles to the fuselage by measuring the distance between the canopy release latch and
the outside end of each half of the horizontal stabilizer – and adjust the horizontal stabilizer so this dis-
tance is the same on both sides of the fuselage.
8) Tape around the opening on the fuselage to prevent excess epoxy from adhering to the covering
9) Using 30-minute epoxy, secure the horizontal stab. Into its slot at the rear of the fuselage, making sure
it is centered
10) Before this epoxy thickens, again make sure that the horizontal stabilizer is aligned at right angles, cen-
tered, and parallel. Once sa sfied, clean up any excess and remove masking tape. A li)le more me
here goes a long way to good flight characteris cs.
Tip
: To prevent excess epoxy from pushing out, brush epoxy onto the horizontal stab on one side
of the exposed area, top and bo)om and then slide in from that side. E.g.,, spread epoxy on the
le hand side, top and bo)om of the horizontal stab about 50 percent across. Then, slowly from
the right hand side of the airplane, insert the stab allowing the epoxy to be spread over the remain-
der of the exposed surface of the stabilizer. Clean up any excess with denatured alcohol on a rag.
Tip:
Verify horizontal stabilizer is parallel to the plane of the wing. This can be done by
u lizing a small bubble level on the horizontal stab and leveling the fuselage. Lightly sand
the saddle to achieve level.
