Cover the tips of the ailerons before the bottom and
top.
Cover the wing TE Plate before the rest of the wing.
NOTE: DO NOT, under any circumstances,
attempt to cut the covering material after it has
been applied to the fin and stab, except around
the leading and trailing edges and the tip.
Modelers who do this often cut through the
covering and part-way into the balsa stab. This
can weaken the stab to the point where it may fail
in flight!
Recommended Covering Sequence:
1. Rudder left side
2. Rudder right side
3. Bottom of elevators
4. Top of elevators
5. Stab bottom
6. Stab top
7. Fin left side
8. Fin right side
9. Fuse bottom
10. Fuse sides
11. Fuse top
12. Fuel tank hatch
13. Ends of ailerons
14. Bottom of ailerons
15. Top of ailerons
16. Wing TE plate
17. Bottom of left wing panel
18. Bottom of right wing panel
19. Top of left wing panel
(overlap covering 1/4" at wing LE)
20. Top of right wing panel
(overlap covering 1/4" at the LE)
When covering concave surfaces, follow the iron
with a damp cloth, pressing the covering down.
FUEL PROOFING
1. Fuel proof the firewall area and the engine
compartment. Black K&B epoxy paint was used for
this on one of the prototypes. Thirty minute epoxy,
polyester resin, or polyurethane-based paints will
also work here.
3. Fuel proof any external exposed wood.
MonoKote matching brush on Chevron Perfect Paint
works nicely here.
HINGING (using CA hinges)
NOTE: CA Hinges are hinges made specifically
to be used with CA glue. These hinges have a
plastic core which is laminated with fibers to
allow the CA to adhere to them.
1. Find the slots you made earlier. Open them up
by cutting a small rectangle of MonoKote away with
a sharp X-acto knife.
NOTE: Keep a folded tissue handy to absorb any
thin CA that may drip onto the MonoKote by
accident. Any glue residue can be completely
removed with CA Debonder
2. Fuel proof the inside of the fuselage forward
of F-2. K & B polyester resin and a bent epoxy brush
were used for this on the prototypes. 30 minute
epoxy also works well for fuel proofing.
