fi rewall on the outside of the motor box.
142. Remove the motor. Move the sliding fi rewall so a thin
coat of 30-minute epoxy can be applied to the motor
box where the plate contacts the box. Slide the plate
into position. Use a paper towel and isopropyl alcohol to
remove any excess epoxy.

the inside of the motor box. Make sure to cut the triangle
stock so it does not cover the blind nuts and fi ts tight into
the corners of the motor box.
144. Attach the motor mount to the fi rewall using four M4
blind nuts, M4 x 20 machine screws, four M4 nuts and
eight M4 washers. Make sure to use threadlock on all
hardware to prevent them from vibrating loose.
145. Use a hobby knife to remove the openings in the sub-
fi rewall to allow the leads from the speed control to enter
