3. Insert the die-cut 1/8" ply F-2A in place against the
10. With the engine resting on the mount, plan the
back of F-2 (do not glue).
4. Insert the 1/4" wing dowels into the wing so they
stick out only 1/8".
5. With the fuselage upside down on a flat surface, 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.
throttle pushrod routing. The pushrod should be located 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.
11. Drill or carve holes in F-2 and F-3 for the guide
tubes. Cut the remaining 36" plastic pushrod guide tube in
half and trial fit the tubes in the fuselage. (Also see the photo
on page 35.)
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 required
lengths and temporarily install the throttle and nose gear
pushrods. NOTE: A 34" wire, threaded one end, is supplied
for the throttle pushrod, and a 19" wire (no threads) is
supplied for the nosegear pushrod.
14. Now remove the pushrod wires, engine, engine
mount and servos.
Measurements must be equal
6. Carefully align the wing in the saddle as follows:

side doublcrs and fuse sides are flush.
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 the saddle slightly until the
wing sits level in the saddle. Also measure from the rear
comer of each wing tip to the tail end of the fuselage. These
measurements must also agree within 1/16". If not, shift the
wing slightly until they do. With the wing in this position you
may now check the wing incidence using an "incidence
