Product overview
The T-MOTOR AT40A 2-4S Fixed Wing Airplane ESC is a power regulation component for integration into fixed-wing aircraft. It uses a switching power supply and incorporates a UBEC, providing motor power regulation and a supply for servos within the controller. The unit weighs 43 grams and supports 2-4S lithium batteries. Its maximum peak current is 55A, and its control features include high-speed throttle response and multiple programmable parameters.
The supplied configuration comprises one T-Motor AT40A ESC and one hardware kit. T-MOTOR recommends AT23 series motors for use with this controller. Its BEC output is 5V/3A, and the built-in UBEC supports five servos operating simultaneously under 4S voltage. That five-servo capability carries the specific 4S qualification, while the controller’s stated lithium-battery support spans 2-4S. These features combine power regulation and servo power provision in a component intended for a fixed-wing installation.
