washers and four M4 blind nuts to secure the wood box to
the firewall. Tighten the screws using a 3mm hex wrench,

with the motor. Attach the motor to the wood box using
the hardware included with the motor. Make sure to use
threadlock on all metal-to-metal fasteners to prevent them

9. Solder any necessary connectors on the speed control.
Mount the speed control following the suggestions included
with the speed control. Connect the speed control to the
motor. Use a 9-inch (228mm) servo extension to connect the
lead from the speed control to the receiver. Route the motor
leads so they don't interfere with the operation of the motor
or installation of the cowling.

10. Secure the two motor batteries in the fuselage using
the hook and loop straps. Use hook and loop tape (not
included) to keep the batteries from sliding on the plate.
Connect the batteries to the speed control using a Y-harness.
