Electric Motor
Plan your motor mounting by determining the length of
the motor, standoff, spacers or washers needed. The
distance between the cowl and the firewall is 6.375”
(162mm). There may be slight variation in the
manufacturing process of the cowl so please check this
dimension. Remember to add a gap between the
spinner and cowl. If using the recommended Hacker Q-
80, you’ll need 3” standoffs to bring the motor forward
to the cowl.
Notice the two centerlines on the firewall. One is the
firewall center and the other represents the motor
mounting centerline offset to compensate for the built
in thrust angle. When lying out the standoff mounting
holes use the offset centerline. This will position the
spinner in the center of the cowl.
opening.
Mount the motor to the standoffs using the hardware
provided by the motor’s manufacturer. We
recommend using large washers on both sides of the
firewall. Don’t forget to use a removable thread lock to
all bolts.
Mount your ESC to either side or bottom of the motor
box.
Cut a hole in the main former for the power wires of the
ESC to get through into the fuselage.
Temporarily connect the 3 motor wires, ESC, receiver,
and battery. Setup your radio and ESC to check the
motor rotation. If the motor rotates the wrong
direction switch 2 of the 3 wires.
Connect your motor and ESC with bullet connectors or
directly solder the wires together.
