BUILD THE FUSELAGE
❏
3. Fit the cowl onto the fuselage. Use the spinner backplate
(you may need to enlarge the hole in the backplate to match the
size of your motor shaft) to center the position of the front of
the cowl 3/32" [2.4mm] behind the backplate. Temporarily tape
the cowl in place or have a helper hold the cowl. Measure back
along the lines from the aft marks on the tape and mark on the
cowl where to drill the four cowl mounting holes.
❏
4. Drill 5/64" [2mm] holes at the marks you made on the
cowl through the cowl and fuse. Remove the cowl and thread a
#4 x 3/8" [9.5mm] self-tapping screw into each hole in the fuse
and back it out. Apply a couple drops of thin CA to each hole
in the blocks. Enlarge the four holes in the cowl with a 1/8"
[3.2mm] bit. Install the cowl onto the fuselage using four #4 x
3/8" [9.5mm] self-tapping screws and four #4 fl at washers.

5. If you haven’t done so already, attach the muffl er to
the engine and connect the vent line from the fuel tank to the
muffl er. Trim it to length if needed.

6. Install your propeller using the prop washer and nut
that came with the motor. Enlarge the propeller slots in the
spinner cone as necessary to fi t over the propeller blades. When
satisfi ed, install the spinner cone onto the backplate using the
provided screws.
❏
7. Fit the canopy hatch in place by fi rst inserting the canopy
pins into their mating holes in the fuse. Push the hatch forward
until the hooks at the aft end of the hatch can fi t into the slots.
Releasing the canopy hatch will allow the magnets to become
attached to the magnets in the fuselage, and engagement of the
hooks. The hatch should now be securely held in place. Now
attempt to remove the hatch in the reverse order.
