The Zagi-20 ESC (Electronic Speed Control) is provided in the kit. The red and black pair
of wires with the red male Deans Ultra connector plugs into the battery. The red and blue pair of wires with the
separate spade connectors plug into the motor. The Zagi-400 uses a pusher configuration which requires a
reverse rotation motor. Reversing the rotation of the motor is achieved by reversing the polarity to the motor.
Look at the flat surface on the back of the motor. Observe the red dot next to one of the motor terminals. For
a positive connection, solder the spade connectors to the motor terminals, the blue wire on the terminal next to
the red dot. The third set of wires is the three wire ribbon lead with the universal RX servo connector. This RX
connector goes to slot in the receiver to control motor speed. The three wire ribbon connector will provide
power for the receiver and servos. No other receiver battery is necessary. The universal connector will work
with all radios except the old Airtronics. The red and black wires must be reversed in the plastic housing of the
universal receiver plug to change to the old Airtronics system.
Make a strain relief to protect the ESC wires from damage on impact. Tether the Deans connector on the ESC
to the motor wire tie with a length of dental floss. The tether will unplug the battery on impact rather than pulling
wires out of the ESC.
Caution: The speed control turns on when the battery is plugged in. Attach the
red and blue wires to the motor before the ESC is plugged into the battery. The prop SHOULD NOT
be installed on the motor at this time.

Trim the canopy along the cut line. The canopy cut lines are more visible when viewed from the
inside. Remove the rear wall of the canopy. Cut out the oval shaped flat surface to make a vent for motor
cooling on the canopy.
