T-Motor Air 20A 3-4S Multirotor ESC

The T-Motor Air 20A is a single brushless ESC for 3-4S multirotors and F3P aircraft. It suits 450-class quads and hexacopters built on separate ESCs and a power distribution board.

Key features

• 20 A continuous and 30 A for 10 seconds

• Firmware tuned for multirotor use, with fast throttle response

• Accepts throttle signal at up to 621 Hz

• Twisted-pair signal lead cuts crosstalk between power and signal

• No BEC: it keeps the signal side isolated, so power the flight controller from a power module or separate BEC

Specifications

• Continuous current: 20 A

• Peak current: 30 A (10 s)

• Input voltage: 3-4S LiPo (11.1-14.8 V nominal)

• Throttle signal: 50-600 Hz, up to 621 Hz

• BEC: none

• Motor connectors: 3.5 mm bullets

Choose motors and props that draw under 20 A continuous on your cell count. Calibrate the throttle range on all ESCs together before the first flight.
