-inch (42mm) aluminum motor standoffs
to the firewall using four 8-32 x 3/4-inch socket head screws
and four #8 washers. The screws will be on the inside of
the fuselage so you will want to have a 9/64-inch ball driver
handy to tighten the screws.
Step 6
Use a drill and 11/64-inch (4.5mm) drill bit to enlarge the
mounting holes in the motor mount plate.
note
: It is highly recommended to use a drill press and
secure the mount. Use caution when using a hand drill
as the mount can easily rotate if the drill bit catches on
the aluminum during the drilling process.
Step 7
Use a #2 Phillips screwdriver to attach the mount to the
motor using the hardware included with the motor. Make
sure to use threadlock on the screws to prevent them from
vibrating loose.
Step 8
Use a 9/64-inch hex wrench or ball driver to tighten the four
8-32 x 3/4-inch socket head screws that attach the motor
to the standoffs. Make sure to use threadlock on all the
hardware attaching the motor and standoffs.
Step 9
Use hook and loop tape (not included) and a tie wrap (not
included) to secure the speed control to the motor box.
Plug the leads together from the speed control and motor,
routing them as necessary so they will not interfere with the
operation of the motor.
