❏ 7. If you will be using a Great Planes T-600R Reverse
Rotation motor with a Great Planes 2.5:1 gear drive, test fit
the motor and gear drive in the motor mount and secure it
with three rubber bands, two behind the gear drive and one
at the back of the motor mount.
❏ 8. Use four #4 x 1/2" sheet metal screws to temporarily
attach the motor mount to the firewall. The direct drive setup
is mounted in the top holes. The gear drive setup is mounted
in the second set of holes, from the top.
❏ 1. Carefully trim the cowl along the mold seam at the back
of the cowl. Use a hobby knife or Curved-Tip Canopy
Scissors to cut out the propeller shaft hole and the vent
holes in the front of the cowl. Also cut out the cooling air exit
hole on the bottom of the cowl.
❏ 2. There are three small indentations near the rear edge
of the cowl, one on top and one on each side, toward the
bottom. These are the mounting screw hole locations. Drill a
3/32" diameter hole at each location.
❏ 3. With your electric motor mounted, slide the cowl into
position. Make sure the propeller shaft is centered in the
hole and there is approximately 1/16" clearance between
the front of the prop adapter and the cowl. Mark the cowl
screw hole locations on the fuselage.
❏ 4. Drill 1/16" diameter pilot holes in the fuse for the cowl
screws. Temporarily mount the cowl to the fuse with #2 x
3/8" sheet metal screws. Do not over-tighten the screws.
