OPTIONAL ELECTRIC MOTOR PREPARATION

 Check the mount of any non-recommended motors
and verify that they can not be attached using the pre-
installed blind nuts. If not, the following outlines how to
modify the firewall for optional motor installations.
1. Mark the fi rewall of the motor box 12mm from the sides and up
5mm from the bottom using a pencil.
2. Place the motor mount on the fi rewall. Align the holes in the mount
on the lines made in the previous step.
3. Look through the back of the motor box to make sure the mount is
centered on the fi rewall. The mount will show equally though the
hole in the fi rewall.
4. Use a pencil to make the locations for the mounting screws through
the mount and on to the fi rewall.
5. Set the mount aside and use a drill and 5/32-inch (4mm) drill bit to
drill the holes in the fi rewall for the mounting screws.

6. Temporarily attach the mount to the fi rewall using four M4 x 20
socket head cap screws, four M4 washers and four M4 lock nuts to
attach the mount to the fi rewall. Use a 3mm hex wrench and 7mm
nut driver to tighten the hardware.
7. When attaching the mount, the washers and lock nut will clear the
pre-installed blind nuts as shown. If not, use a hobby knife and #11
blade to trim the wood around the nuts and washers so the washers
rest fl ush on the wood. Remove the mount from the fi rewall.
8. The mount can now be attached to the motor using the hardware
included with the motor. Use a drop of threadlock on each screw to
prevent them from vibrating loose.
9. Attach the propeller adapter to the motor using the hardware
included with the adapter. Use a drop of threadlock on each screw to
prevent them from vibrating loose.
