Product overview
The T-MOTOR AIR 20A 3-4S is a FOC electronic speed controller for brushless motors in multirotor UAVs and F3P aircraft. It supports 3-4S LiPo batteries and control signal frequencies up to 621Hz. Its control program is intended to improve throttle response and multirotor flight stability, while pre-configured settings simplify setup and support adaptive operation. A twisted-pair signal cable is designed to reduce crosstalk in the signal connection.
The package contains one T-MOTOR AIR 20A 3-4S ESC and one hardware kit. Matching guidance identifies the T-MOTOR MN3110 and MN3510 motors, while compatible propulsion kits include the T-MOTOR 355 DIY Drone Kit, 355 Quick-Release Drone Kit and AirGear 450II DIY Drone Power Kit for lightweight multirotor UAV applications.
