BL15 Ducted Fan 3200 Kv Brushless Motor Instructions
Thank you for purchasing the E-flite BL15 DF Brushless Motor. This motor is an ideal choice for products such as Parkzone’s Habu EDF and other similar sized ducted fan airplanes when using the purpose-built Delta-V 15 69mm EDF (EFLDF15). The motor will provide great performance in 68-70mm diameter fan units requiring a 28mm inrunner motor. This is a lower current alternative to the 3600Kv BL15 DF motor and works better in applications where cooling is limited such as in foam models.
BL15 DF 3200Kv Motor Features:
•Purpose-built for the Delta-V 15 69mm EDF (EFLDF15)
•Replacement motor for Parkzone Habu EDF
•Ideal for 68-70mm EDF units requiring a 28mm diameter inrunner motor
•Ideal for up to 800 input watts
•High-quality construction with ball bearings and hardened steel shaft
•6-pole design

Cells: 3S-4S Li-Po or 10-14 Ni-MH/Ni-Cd
Recommended Ducted Fan Unit: Delta-V 15 69mm EDF (EFLDF15) Static Thrust: 1.7 lbs on 3S (11.1V) – using recommended Delta-V 15
2.8 lbs on 4S (14.8V) – using recommended Delta-V 15 RPM: 33,800 on 3S (11.1V) – using recommended Delta-V 15
45,700 on 4S (14.8V) – using recommended Delta-V 15 Brushless ESC: 50A – 60A
*Maximum Operating Temperature: 220 degrees Fahrenheit
*Adequate cooling is required for all motor operation at maximum current levels.
*Maximum Burst Current duration is 15 seconds. Adequate time between maximum burst intervals is required for proper cooling and to avoid overheating the motor.
*Maximum Burst Current rating is for full high power and limited motor run flights. Lack of proper throttle management may result in damage to the motor since excessive use of burst current may overheat the motor.

Operating Instructions:
1.This brushless motor requires the use of a sensorless brushless speed control. Failure to use the correct speed control may result in damage to the motor and/or speed control.
2.When mounting the motor, be sure the correct length of screws (5mm) are used so damage to the inside of the motor will not occur. The use of long screws will damage the motor.
3.You may connect the three motor wires directly to the controller with solder or use connectors such as gold plated brushless bullet connectors (EFLA241), which will also need to be soldered properly to your wires. The three motor wires can be connected in any order to the three output wires or output port on a sensorless brushless speed control. Be sure to use heat shrink tubing to properly insulate the wires so the wires will not short. Shorting may damage the motor and speed control.
4.If you add connectors and or you no longer wish to use them, never cut the motor wires. Remove them by properly de-soldering them. Shortening the motor wires is considered an improper modification of the motor and may cause the motor to fail.
5.When you connect the motor to the esc, check the rotation direction of the motor. If you find the rotation is reversed, switching any two motor wires will reverse the direction so the motor rotates properly.
6.Proper cooling of the motor is very important during operation. New technology has brought much higher capacity batteries with higher discharge rates, which can cause extreme motor temperatures during operation. It is the responsibility of the user to monitor the temperature and prevent overheating. Overheating of the motor is not covered under any warranty.
7.You can install the rotor/propeller on the motor shaft after you have confirmed proper rotation direction. Also consult the instruction included with your sensorless electronic speed control for proper adjustments and timing.
8.Once the battery is connected to the motor, please use extreme caution. Stay clear of the propeller/ducted fan rotor during operation. Spinning propellers/rotors are very dangerous as the motors produce high amounts of torque.
9.Never disassemble the motor. This will void any warranty.
Motor Safety Precautions:
The motor will be used in an EDF unit that contains a rotating part so use extreme caution. Please read the warning information included with your fan unit / propellers for safety information related to the operation of motors with propellers. Failure to comply with these warnings and/or improper use of propellers or EDF units may result in serious injury.
Limited Warranty Period
Horizon Hobby, Inc. guarantees this product to be free from defects in both material and workmanship for a period of 1 year from the date of purchase.
