WattAge IC-380AS Electronic Motor Control - Operation Guide



The Wattage IC‑380AS Electronic Motor Control is designed for DC Brush type motors in Electric Aircraft.  It's factory installed plugs make it easy to install in most electrics For those with experience, weight can be saved with smaller connectors and direct wiring to the motor. The IC‑380AS is designed to extend motor and battery life and flight time. It's high frequency and smooth powerband minimize current loss and reduce motor brush arcing. Please read this guide carefully before operating your IC‑380AS




1. Do not short‑circuit any of the wires.

2. Do not attempt any type of soldering or de-soldering on the speed control PC Board.

3. Follow the input and output wiring carefully. Connecting the battery to the motor leads will produce immediate speed control failure and possibly fire, and is ot covered by the warranty.

4. Double check the plug wiring polarity and order before connecting the speed control to the receiver.

5. Keep hands, body parts, and any objects out of the way of the propeller. Test the speed control operation before installing the propeller.

6. Do not subject the speed control to moisture or water.

7. Do not attempt to operate the speed control outside of its specifications.

8. Keep the speed control out of direct sunlight and away from extreme temperatures.

9. Keep the speed control away from the receiver and receiver antenna.

10. Install proper motor capacitors on the motor.




1. Smooth Throttle Curve: When changing the throttle settings, the speed will softly change. This is a motor anti‑load device. For example, if the throttle stick is moved abruptly, the operation is smoothed by the ESC. This will reduce motor overload and increase brush life and run‑time.

2. Anti noise or loss of signal (up to 1 second): When a loss of signal is experienced, the ESC will keep the last known motor speed setting for about 1 second. Minor and brief interference will not affect the power to the motor.

3. Cancel the delay for reset at normal operation: After the safety has be set the first time, when the throttle is set again to minimum (the reset point), the ESC does not need any delay time for reset. The pilot can apply the throttle any time, the output will begin immediately.

4. BEC/Auto-Cutoff Reset:: After the auto‑cutoff has engaged, (when the battery has reached the minimum safe voltage) the ESC will reset after the throttle stick is held in off position. Low battery voltage will result in the motor cutoff but reserve battery power can used to reset the speed controller in the air to for a safe return to the field.

5. Lightweight: In its class, it is light and small so it is easily installed in your favorite aircraft.



1. Install the capacitors to the motor. One capacitor connect the terminal to the side of the case. The last capacitor connects the two motor terminals.

On each motor terminal, solder a capacitor from the terminal to the side of the motor case.

Capacitors eliminate electronic noise from the motor. This prevents radio interference.


2. Connect the ESC motor leads to the motor.

3. Remove the propeller from the motor for safety. Once the testing is complete, the propeller may remain installed on the motor.

4. Connect the speed control to the receiver. Check the polarity and plug orientation.

5. Turn on your transmitter.

6. Check the polarity of the battery and the ESC Battery leads. Then connect a charged battery to the ESC.

7. Adjust the trim or ATV on the transmitter so that the motor is off when the stick is in the low position.

8. Move the stick to full throttle position. The motor should run at full speed. To check this, while the stick is in the full throttle position, measure the voltage with a voltage meter at the motor and then at the battery. The voltage reading should be the same.


Note: If full throttle is not reached, it may be necessary to increase the ATV settings for the throttle on your transmitter.


Note: If the throttle stick works backwards (low throttle stick is full motor speed) use your transmitter's servo reversing function. If the motor runs backwards, switch the polarity of the MOTOR Leads. NEVER reverse the polarity of the battery leads.


9. When the battery has reached a voltage too low to safely operate the radio and the motor, the motor will be switched off. The motor can be rearmed by positioning the stick to the low position. In this way, low throttle setting can still be used so that you may have some power to the motor.
