Adding the Battery Connector
The battery connector is attached to the side of the controller that has only two power wires, and also has the
radio connector. Cut the wires to the length you require on the battery side. Strip off of the wire insulation to
expose just enough wire to attach the battery connector. (Note: if you do not have a pair of wire strippers,

Warning!
High power motor systems can be very dangerous! High currents can
heat wires and batteries, causing fires and burning skin. Follow the wiring directions
carefully! Model aircraft equipped with high power motors can kill. Always fly at a
sanctioned field. Never fly over or near spectators. Even though this controller is
equipped with a safety arming program, you should still use caution when connecting the
main battery.
you can use a modeling knife to carefully cut through the insulation around the wire. Then the insulation
should easily pull off the wire.) Attach the battery connector to the wires ENSURING THAT THE
POLARITY (red wire to battery red wire, black wire to battery black wire) IS CORRECT, following the
instructions for the battery connector.
IMPORTANT NOTE: YOU MUST BE SURE THAT THE POLARITY IS CORRECT WHEN
CONNECTING THE SPEED CONTROLLER. Incorrect polarity could permanently damage the controller.
2.3
Connecting the Motor
The motor is connected to the side of the controller that has THREE power wires. Cut the wires to the length
you require on the motor side. DO NOT CUT the wires leading from the motor. Strip the wire insulation to
expose just enough wire to solder the wires to the motor terminals. There should be three wires extending
from the motor. Connect the three speed control wires to the three motor wires. Align the wires carefully and
solder to the motor wires. Ensure that all connections (battery and motor) are correctly polarized.
2.4
Reversing Rotation
Bench test the motor connections noting the rotation of the motor. To change the rotation of the motor, swap
ANY two motor wire connections.

Connecting the Receiver
Older AirTronics systems require a minor change to the wiring in the receiver connector supplied with the
speed controller. Reverse the red (power) and brown (ground) wires in the connector plug so that the plug is
orange/brown/red. Use a knife blade to lift the retention tabs on the connector plug to remove the red and
brown wires. Insert the wires back into the plug and press down the retention tab.
Connect the receiver lead (the three color twisted wires with a connector on the end) to the throttle channel on
your receiver (usually channel 3). Do not connect a battery to the receiver, as the Phoenix-25™ will supply
power to the receiver and servos through the receiver connector. If you are using more than ten cells, you
must use a separate receiver battery. See the section 4.0 (under the heading BEC) for instructions on
disabling the BEC to use a separate receiver battery.
