Instruction manual

2. Engine (or Motor) and Cowl –

a. Test-fit your engine, the engine mount, fuel lines, throttle pushrod and all related engine-mounting

hardware as shown below.

b. Using the spacing required by your engine’s mounting lugs, drill holes in the engine mounts and use

engine mounting bolts, washers and nuts (#6-7-8 above) to securely attach your engine to the engine

mounts. Test-fit the engine to the firewall using the vertical and horizontal guide-lines drawn on the fire

wall to set the prop. shaft with the recommended amount of right thrust and down thrust. Drill 4 holes in

the firewall.

c. Use engine mounting bolts (#4 above) and blind nuts (install the blind nuts behind fire wall) to attach the

engine to the fire wall.

d. Drill a hole and direct the throttle pushrod (#10 above) from the throttle servo through the firewall. (Be

careful to position the throttle pushrod’s hole so it will not interfere with the engine mount or fuel tank.)

e. Position the fuel tank (#1 above) on its shelf inside the fuselage behind the firewall with the clunk and

vent fuel lines passing through the firewall.

f. In preparation to mount the engine cowl (#9 above), remove the muffler from your engine.

g. As dictated by the design and dimensions of your engine, make opening in the engine cowl to access

your engine’s needle valves, allow cooling air into the cowl, and to let the muffler exit the cowl.

h. Attach the engine’s muffler to the engine with its provided hardware.

i. If you are using the optional dummy engine, attach the engine parts to both sides

of the cowl at this time. Position the cowl so the propeller backplate protrudes

approx. 1/4 inch beyond the face of the cowl; use masking tape to temporarily

hold the cowl in position; drill guide holes through the cowl and into the edge of

the firewall; use small screws to attach the cowl; remove the masking tape.

If you install an electric power system …

a) Position your batteries on the shelf behind the firewall.

b) Position the optional motor mount-

ing box and your motor on the

firewall as described above to

obtain the recommended amount of

right thrust and down thrust.

Protect the mounting bolts from

vibration with thread lock

compound or CA adhesive.
