NOTE: When covering the fin and stab, begin by
applying 1/2" wide strips of covering in the comers
between the fin and stab, and (on the bottom of the stab)
between the stab and the fuse. sides. Next, cover the stab
and fin with pre-cut pieces that have a straight edge to
overlap (1/8"+ overlap) the strips you previously
applied. 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. Strips as described in above note

2. Rudder left side

3. Rudder right side

4. Bottom of elevators
5. Top of elevators
6. Stab bottom
7. Stab top

8. L.G. slot
9. Fuse bottom

10. Fuse sides
11. Fuse top
12. Fin left side
13. Fin right side
14. Ends of ailerons
15. Bottom of ailerons
16. Top of ailerons
17. Aileron openings in wing
18. Bottom of left wing panel
19. Bottom of right wing panel

20. Top of left wing panel (overlap covering 1/4 "at wing

LE)

21. Top of right wing panel (overlap covering 1/2" at the

center and 1/4" at the LE)

APPLY DECALS AND TRIM

NOTE: The decal sheet does not give you everything
you need to completely trim your model; but it does
provide all the intricate detailing and difficult items. The
complete trim layout is shown on the back of the fuselage
plan.

D 1. Study the plans and the photos on the box to deter-

mine where to place the decals.

D 2. Thoroughly clean your airplane before applying

decals.

D 3. Cut out the individual dccal items and apply them in

the locations shown on the plan. NOTES: For case of
application, when cutting out the "starburst" decals, cut
along a curving line around the star, rather than trying to
follow all the star points. The "PETE" dccal should be
applied upside down to the left wheel pant. "EXPERIMEN-
TAL" may be applied to the inside of the cockpit, just under
the right front window (Yes, this is the scale location). The
