Step 4. The Hangar 9
™
Engine mount fits nearly all .40–58
two-stroke engines and .50–72 four-stroke engines. Trial fit
your engine into the engine mount.
Step 5. For engines that do not fit in between the beam mount-
ing rails of the engine mount, use a moto-tool with drum sander
or file and carefully remove equal amount of material off the
inside of the mounting beams to just allow your engine to insert
between the rails. Be careful not to remove too much material, as
this could weaken the engine mount.
Step 6. Note the proper orientation of the engine mount to the
firewall. The head of the engine will be to the right side of the
airplane (as viewed from the aft end of the fuselage or from the
pilots perspective when sitting in the cockpit).
Step 7. Secure the motor mount to the firewall by installing the
four bolts through the engine mount bolt holes and into the pre-
installed blind nuts in the firewall. It is a good idea to use
threadlock on the mounting bolts before installing them through
the engine mount and into the blind nuts.
Step 8. Before installing your engine onto the engine mount,
insert the fuel tank into the fuselage. The two pieces of fuel
tubing should exit through the center hole in the firewall. Use
protected foam (not included) under and behind the fuel tank
and/or around the fuel tank to secure it in place.
