the cockpit sides. Sand the bottom edge at an angle to

mate with the cockpit floor (fuse top front). Glue the dash

the top front block, cockpit sides and cockpit floor.

17. Mark the outline of the engine mount on F-l

with a pencil. Remove the prop nut and propeller. Pop

the spinner backplate loose with a screwdriver and

remove the spacers. You may remove the engine and

mount in preparation for the next step. HINT: After

removing the engine, enlarge the hole in the spinner ring

as necessary until you can easily access the engine mount

screws with a long screwdriver.

21. Temporarily re-install the engine and mount;

then, from the remaining 1/4" balsa sheet and 1/2" balsa

triangle, cut pieces to partially fill in the right side

around the engine. Also, trim the balsa as necessary to

clear your muffler. SUGGESTION: The temptation is

to close up this area too much! We recommend that you

leave large enough openings that you may easily remove

the engine and mount, and so you will have convenient

access to the throttle linkage.

18. A 1/4" x 3" x 8" balsa sheet is provided for the

nose sides. From this sheet, cut a piece to fit on the left

side of the fuselage between the chin block, top front

block, F-l and the spinner ring. To do this more easily

you may remove the engine and mount, then lay the fuse

on its left side on top of the 1/4" balsa sheet and mark the

outline of the opening on the sheet. When installing this

block, make sure you stay clear of the engine mount.

19. If necessary, carve out an area of the nose side

needed for nosegear steering arm and pushrod clearance,

then glue the left nose side in place.

20. From the 1/2" balsa triangle stock provided, cut

lengths to fit in the upper left and lower left comers of the

nose, between F-1 and the spinner ring. Sand these balsa

triangles to a taper, with the wide part at the front, and

glue in place.

FINAL ASSEMBLY

SAND THE FUSELAGE

NOTE: Some heavy sanding is required to properly

shape the nose area. This task can be made much

easier if you use a razor plane and a sanding block

with #50-grit sandpaper for the rough shaping. The

very coarse sandpaper is used to achieve the basic

shapes, then use progressively finer grades of sand-

paper for a smooth finish.

1. Turn the fuse upside down and draw a line on the

aft end of the chin block 9/32" below the bottom edge of

F-2A. Now study the fuse plan side view and note the

final shape and curvature of the chin block. Use your
