Loosely install prop on engine. There should be 1/8” to
1/4” clearance between back of prop and cowl.
Attach cowl to fuse using #2 x 3/8” screws and
washers. Remove prop and cowl. With engine still on
mounts proceed directly to step 35.
35.
Bolt the motor mounts to the firewall, using the four
4-40 x 1” bolts with a #4 flat washer.
Mount the engine, refer to the plan for the correct thrust
orientation. Drill a 1/16” pilot hole for each #6 x 3/4”
mounting screw. Check the cowl fit-up after you install the
engine.
36.
For rear end of elevator and rudder pushrods, bend
both 10” threaded rods as accurately as possible over
plan.. Cut off excess, leaving about 1/4” at right angle.
Using threaded end of a rod, file a slight recess 1-1/4”
long at one end of each 3/8” square balsa pushrod. (The other
end of the pushrod is completed later during radio installa-
tion).
Drill a 1/16” dia. hole at end of recess in both
pushrods.
Glue rods into balsa pushrods as shown.
When dry, taper ends of pushrods and round off corners.
bind with strong thread, coat with glue and let dry.
#2 x3/8” SHEET METAL SCREW
TO INSTALL #2 SCREW,
FIRST DRILL 1/16” DIA
HOLES.
37.
Insert formed wire L.G. struts in fuse. Position nylon
landing gear straps; then mark, drill, and mount with #2 x
3/8” screws (see above and illustration on page 5).
38.
Cut open straight action end of four nylon hold-downs.
Grasp at center hole and bend it over (it will spring back to
proper angle).
#2 x3/16” SHEET METAL SCREW.
Lay L.G. fairings down left and right as shown and
install hold downs using #2 x 3/16” sheet metal screws at
punch mark locations. Position them with straight action
end facing up towards center.
#2 SHOULDER SCREW
39.
Align fairing front with L.G. strut and adjust so hold
downs project over fuse bottom. Mark, drill, and mount
fairings with #2 shoulder screws (exposing enough un-
threaded shank to engage hold-down). Later when flying,
hold lower fairing to strut with a rubber band.
