2. Temporarily attach the motor mount to the fi rewall with
two 6-32 x 3/4" [19mm] SHCS or hold the motor mount in
position while you mark the location for cooling holes in the
location shown. There should be an elliptical-shaped hole on
both sides of the mount. Use a rotary tool to cut out the holes
before attaching the mount. When satisfi ed with the size and
shape of the holes, attach the motor mount to the fi rewall
using four 6-32 x 3/4" [19mm] SHCS, four #6 fl at washers,
four #6 lock washers, and thread locking compound.
❏
3. Loosen the screws that hold the aluminum motor mount
halves together and slide them apart as necessary so that the
front of the prop adapter is 4-7/8" [124mm] from the fi rewall.
When adjusting the mount, do not inadvertently create an up
or down motor thrust angle. Use thread locking compound
on the screws that join the motor mount halves.

4. Assemble the ESC tray as shown. Use pieces from the
included 6x6mm triangle stock to reinforce the tray sides.
❏
5. Attach the ESC to the tray using three 3x12mm self-
tapping screws. Be sure to harden the screw holes with thin
CA. Other brand ESCs may need to be attached to the tray
with tie straps (not included) or a hook and loop strap.
