of the blind nuts to glue them in place (be careful not to get
glue in the threads). The holes in the front piece are slightly
off-center to accommodate the motor right thrust. Be sure
that the blind nuts are installed on the correct side as
shown. Assemble the box as shown with medium CA glue

mounting box assembly to the fuse, being sure that the box

thread-locking compound to attach the plywood motor
adapter to the back of the out-runner motor case.
