Operating Instructions
1. This brushless motor requires a sensorless brushless speed
control (electronic speed control or ESC). Failure to use the
correct ESC may result in damage to the motor and/or speed
control. Refer to your ESC instructions for correct operation
with this motor and a propeller.
2. Where needed, always attach motor with short screws that
do not enter and damage the motor. Use screws and other
hardware included with your motor.
3. Where needed, install included 3 bullet connectors (EFLA249)
on the output wires of your ESC using solder and heat shrink
insulation (to prevent short circuiting). The 3 motor wires can
be connected in any order to the 3 ESC output wires or output
port on an ESC.
4. Make sure the motor turns in the correct direction for your
model. Change the direction the motor turns by changing the
connection of any 2 motor wires on the ESC.
5. Install a propeller on the motor shaft after you ensure the
motor turns in the proper direction.
6. Make sure the motor is mounted on the model to ensure good
air circulation during operation. The motor generates heat
when operated at maximum power. The user is responsible
to make sure the motor does not overheat. Overheating the
motor is not covered under any warranty.
7. Never cut or otherwise change the length or size of motor
wires. Remove connectors by heating and removing solder.
CAUTION: When the motor is connected to power, use
extreme caution or injury and damage can result. Motors
turn propellers at dangerously high RPM (revolutions per minute)
so stay clear of the motor and propeller during operation.
NOTICE: Any modi cation of the motor that is not approved by
Horizon, including changing the motor wires, may damage the
motor. It will also void the warranty and result in refusal of service
by Horizon.
Changing Shaft Orientation
1. Loosen the setscrew on the shaft collar and remove the collar
from the shaft.
2. Loosen the two setscrews on the rotating end of the motor.
3. Push the shaft through the motor. A small hammer is required
to lightly tap the shaft.
CAUTION: DO NOT bend or damage the motor shaft as
injury or property damage may result.
4. Install the shaft collar against the bearing using the setscrew.
5. Tighten both setscrews on the rotating end of the motor.
Tighten one setscrew against the  at face on the motor shaft.
NOTICE: At  nal assembly, apply a small amount of threadlock
(example A shown in illustration) to setscrews to keep these
fasteners from becoming loose. DO NOT use a large amount of
threadlock as this may result in damage to the motor.
