400 Ducted Fan Brushless Outrunner Instructions
Thank you for purchasing the E-flite 400 DF Brushless Outrunner motor. This motor is an ideal choice for the E-flite Super Airliner and small Ducted Fan airplanes. The motor will provide great performance on 66mm diameter fan units with three blade impellors.
400 DF Brushless Outrunner Features:
•Ideal for small Ducted Fan models from 15to 25-ounces using 3-cell 2100mAh Li-Po battery packs
•High Torque alternative to inrunner brushless motors
•Quiet, lightweight operation – just 2 ounces (56 g)
•External rotor design
•High quality construction with ball bearings and hardened steel shaft
•Slotted 9-pole Outrunner design

*Maximum Operating Temperature: 175 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 3D 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.
Battery Choices:
There are many Li-Po battery brands on the market with several choices for consumers. We recommend either E-flite or Thunder Power batteries and list some possible choices for the
400 DF Brushless Outrunner motor, all-depending on the airplane application.

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 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 you no longer wish to use them, never cut the motor wires.
Remove them by properly desoldering 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 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 rotating propeller since spinning propellers are very dangerous as the motors produce high amounts of torque.
9.Never disassemble the motor. This will void any warranty.
