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, 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

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.
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 t hree 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
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.
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.
Flying with Your Phoenix-25™:
3.0
ALWAYS PERFORM A RANGE CHECK BEFORE FLYING WITH ANY NEW SPEED
CONTROLLER! PERFORM YOUR RANGE CHECK AT FULL THROTTLE, HALF
THROTTLE AND NO THROTTLE.
Initialization sequence:
1. Connect the speed controller receiver connector to the proper channel on your receiver (usually
channel 3)
2. Turn on your transmitter.
