throttle pushrod routing. The pushrod should be lo-
cated as close as possible to the fuse sides (to allow room
for the fuel tank), and the guide tube should not have any
tight bends. Drill a 3/16" hole in F-l for the throttle
pushrod guide tube. 2. Sand the entire wing saddle area lightly until the
fuse side doublers and fuse sides are flush.
3. Insert the die-cut 1/8" ply F-2A in place against
the back of F-2 (do not glue).
11. Drill or carve holes in F-2 and F-3 for the guide
tubes, and trial fit
4. Insert the 1/4" wing dowels into the wing so
they stick out only 1/8".
12. Sand the plastic pushrod guide tubes with 100-
grit sandpaper, then glue them in place. Trim and sand
the tubes flush with the front of F-l.
13. Cut the pushrod wires (supplied) to the re-
quired lengths and temporarily install the throttle and
nose gear pushrods. NOTE: A 34" wire, threaded one
end, is supplied for the throttle pushrod, and an 18" wire
(no threads) is supplied for the nosegear pushrod.
14. Now remove the pushrod wires, engine, engine
mount and servos.

trial fit the wing into the wing saddle. If the wing is
slightly too large (front to rear) to fit into the saddle, sand
the rear edge of the saddle and the wing trailing edge
slightly until it fits.
2. From the 3/32" x 3" x 16" balsa sheet, cut and
glue pieces of cross-grain sheeting to the bottom of the
fuse, beginning at the front of F-4 and running to the aft
end of the fuse.
3. Sand the edges of the bottom sheeting flush with
the fuse sides.
6. Carefully align the wing in the saddle as follows:

MOUNT THE WING TO THE FUSE
1. Sand the top surface of the fuse to remove any
excess glue so the fuse will lie flat on the workbench.
If you have drilled the dowel holes accurately, the
wing should now be centered, side to side. Measure
down from the bottom of both tip ribs to the flat surface.
If the measurements are not equal (within 1/16"), sand
