2. Attach the out-runner motor to the brushless motor
mount using the included 3 x 8mm machine screws and 
threadlocking compound. If you haven’t done so yet, install 
the prop adapter to the motor case with the hardware 
included with the motor and threadlocking compound.
❏
3. Attach the motor mount to the fi rewall using four
6-32 x 1/2" [13mm] SHCS, four #6 fl at washers, four #6 lock 
washers, and threadlocking compound.
❏
4. Loosen the screws that join the aluminum motor mount
halves and slide them together so that the front of the prop
adapter is 4-7/8" [124mm] from the fi rewall. When adjusting 
the aluminum motor mount, take care not to inadvertently 
increase or decrease the amount of right thrust from what is 
already built into the motor mounting box.
❏
5. Knock out the cooling hole in the bottom of the fi rewall.
❏
6. The mounting holes in the included ESC tray match
the mounting pattern of the recommended Great Planes 
brushless ESC. Other brand speed controllers can be secured 
to the tray with the included hook and loop material.
❏
7. Make a strap from the included hook and loop material
by overlapping the mating ends by approximately 1" [25mm]. 
If you are installing the recommended Great Planes ESC, 
make the strap 6" [152mm] long. If you are using a different 
brand ESC, you can use the strap to secure the ESC to the 
tray. The total length of the strap will be determined by the 
size of the ESC.
