2. Assemble the “X” mount and the propeller shaft to
your motor. Mount the motor mount box with four M3 x 12
Phillips machine screws and M3 fl at washers, lock washers
and threadlocker.
❏
3. Connect the ESC to the motor and mount it to the bottom
of the motor mount box. For the Castle Creations Edge Lite
75 ESC we soldered the female bullet connectors that came
with the motor to the three motor wires (protected with 3/16"
heat shrink tubing) and a
Star
connector to the battery wires.
Then we mounted the ESC to the box with a piece of foam
rubber and nylon ties.

4. Power up the ESC with the receiver and transmitter
and run the motor to make sure it turns the correct direction.
If the motor turns the wrong direction, swap any two of the
three motor wires (or reverse the
motor direction
in the ESC
programming if available).

3/4" [20mm] deep. Test fi t the cowl to make sure the slot is
wide enough and deep enough to fi t the cowl.
