7. Use a propeller reamer to enlarge the hole in your
propeller and in the spinner backplate (this can be made
easy by “chucking” the reamer into a power drill). Mount the
spinner backplate and a balanced propeller to the motor with
the washer and nut included with the motor. Then, mount the
spinner cone with the screws that came with the spinner.
❏
8. Use a hobby knife with a sharp #11 blade to cut the
covering from the rounded air exit slots in the bottom of the
fuselage behind the wing.
Proceed to Mount the Fuel Tank (or Motor Battery).
Mount the Engine
❏
1. Temporarily mount the two-piece engine mount to the
fuselage with four 6-32 x 1" [25mm] Phillips screws, four #6
lock washers and fl at washers, but don’t tighten the screws
all the way yet.
❏
2. Place your engine on the mount, sliding the mount
halves together or apart to fi t the engine. Now you may
tighten the mount bolts the rest of the way.
❏
3. Place the backplate of the spinner on the engine and
position the engine on the mount so there will be a 1/8" [3mm]
space between the backplate of the spinner and the front of
the fuselage. Note: Most 4-stroke engines will not be able
to be positioned far enough aft on the mount to achieve this
spacing, so just move the engine as far back as possible.
❏
4. Use a Great Planes Dead-Center Hole Locator
(GPMR8130) or a sharpened wire to mark the location of
the engine mounting holes onto the mount.
