The engine pod is blowmolded plastic. To cut this material, score
a few times with a sharp utility knife. Once a cut-out is made, you can
whittle away the rest or use a Dremel tool with a sanding drum.. Work
carefully. It is easy to cut too much away; it is also easy to cut yourself.
Begin by separating the front from the rear by cutting along the
line indicated. Also make the rectangular cutout in the bottom of the
rear of the pod, extending the cut to the front edge of the part.
Test fit the parts onto the engine mount assembly so both halves
meet in the middle of the firewall.

Position your engine on the engine mount (note that the mount's
beam width is adjustable to accommodate your engine). Locate the
engine on the mount so the front of the prop's thrust washer is 4 1/4"
from the front surface of the firewall. Double check that this set-up
gives you 1/8"-1/4" of spinner clearance from the front of the engine
pod. Mark then drill pilot holes using a 3/32" bit. Mount your engine
using the four M3 X 15mm screws.
NOTE: A bench vise makes a handy holding fixture while you are
working on your engine pylon assembly.

Trim the front engine pod to clear the cylinder head, muffler, nee-
dle valve, and carb. A utility knife and Dremel tool with a sanding drum
makes easy work of this task.
Both the front and rear engine pod are secured with the furnished
2X8mm self tap screws. (Four for the front and four for the rear.) Drill
1/16" pilot holes for the screws.
ENGINE POD ASSEMBLY/FUSELAGE ASSEMBLY

Remove the front and rear pod halves. The throttle servo is
mounted on the right side of the engine pylon behind the firewall
using servo tape. The throttle linkage consists of a length of music
wire with a "Z" bend on the throttle arm end and an EZ connect on the
servo arm end. The servo cable goes into the slot that is machined in
the rear of the engine pylon.

Assemble the fuel tank as shown. The fuel tank is housed in the
rear engine pod and held in place with lightly wrapped foam rubber.
Fuselage Assembly

To prevent damage, have a piece of foam over your work surface
to rest the hull of the fuselage upon as you work on it. Cut away the
covering film that is over the slot for the engine pylon, leaving 1/4"
excess all along the slot. Cut the film diagonally to each corner and
then use a heat sealing iron to seal the edges along the inside surfaces
of the slot.
