 Step 1

Position the engine on the engine mount so the drive

washer is roughly 1/8" (3mm) forward of the sides of the

fuselage. Mark the location of the engine mounting bolts

using a felt-tipped pen.

Note: The engine must be far enough

forward so when the propeller and spinner

are installed, they don't bind on the front

of the fuselage. A quick check is to slip the

spinner backplate on and check for clearance.

 Step 2

Use a 5/32" (4mm) drill bit to drill the holes in the

engine mount.

Hint: Remove the mounts and use

a drill press to get the holes in the

mount perpendicular to the mount.

 Step 3

Mount the engine to the mount using four

8-32 x 1

" screws, four #8 washers and four

8-32 locknuts.
