1. Locate the four pieces that make up the motor
mounting box and the four blind nut doublers. Install 3mm
blind nuts into each of the four blind nut doublers. Glue the
doublers to the back of the front piece of the mounting box.
The holes in the front piece are slightly off-center to
accommodate the motor right thrust. When gluing the
doublers to the front piece, be sure that the blind nuts are
closer to right side when the mounting box is glued together.
Assemble the box as shown with medium CA glue (the
longer side piece being on the left of the box). The front
piece is installed in the aft slots.

2. Attach the aluminum adapter to the back of the out-
runner using the screws supplied with the motor. Attach the
motor to the mounting box with four 3mm x 6mm machine
screws, four 3mm washers, and thread-locking compound.
❏
3. Thoroughly glue the mounting box assembly to the
fuselage by sliding it on the box already attached to the
fuselage. Be sure that the box is flat against the
fuselage firewall.

1. The ESC and receiver will be secured inside the plane
with double-sided servo tape (not included). For better
adhesion of the tape, brush on a light coating of epoxy to the
fuselage former above the landing gear and the back of the
