T-Motor AT 75A 6S Fixed-Wing ESC

The T-Motor AT 75A is a single brushless ESC from T-Motor's AT fixed-wing line. It is rated for 2–6S LiPo, and T-Motor pairs it with its AT2814 and AT2820 motors. It suits fixed-wing UAVs and other single-motor airframes that need a 75A controller with a built-in supply for servos and receiver. Its start modes also cover helicopters and multirotor arms.

Key features

• 75A continuous and 95A burst current on 2–6S LiPo (7.4–22.2 V nominal)
• Switching BEC delivering 5 V at 5 A for servos, receiver and flight electronics
• Accepts throttle signals up to 621 Hz; the twisted-pair signal lead reduces crosstalk
• Low-voltage cut-off, over-temperature and throttle-signal-loss protection
• Normal, Soft and Super-Soft start modes; every setting except timing comes preset
• Configurable throttle range. With the optional T-Motor program card you can change settings at the field and pick from 15 start-up tunes.

Specifications

• Continuous current: 75 A
• Burst current: 95 A
• Input: 2–6S LiPo
• BEC: switch mode, 5 V / 5 A
• Throttle signal: up to 621 Hz
• Weight: 82 g

Before you buy, check your motor's full-throttle current with the propeller you plan to fly. It should stay comfortably below the 75 A rating. The 5 V / 5 A BEC can feed the servos directly, so lighter airframes often need no separate UBEC.
