Como convertir micro servo en controlador de velocidad (ESC) para motores corriente continua

ELECTRONICS: FlySky FS-i6 transmitter. Receiver FS-iA6. Micro servo (in this case, a TowerPro SG92R of 9 grams). DC motor (in this case, an 8520 motor that runs between 3 and 5 volts). Battery 1S of 3.7 volts running at full capacity (4.2 volts) or a 2S of 7.5 volts that runs at half voltage (less than 6 volts). The receiver accepts a voltage between 4 and 6 volts. Otherwise, it produces an alarm sound due to inadequate voltage. Two resistors of 2.200 Ω. CONFIGURATION OF THE FLYSKY TRANSMITTER: I have the transmitter in mode 2, that is, with the throttle in channel 3. So, for channel 3, you should: Reverse the direction in the Reverse menu (if needed). Trim the neutral point in the Subtrim menu. In addition, you have to adjust the throttle curve in the Throttle Curve menu. The curve must be adjusted by setting the value 50% at point L; 50% at point 1; 50% at point 2; about 60% at point 3 and 100% at point H.
