T-Motor F55A Pro II 55A 3-6S BLHeli_32 4-in-1 ESC

The T-Motor F55A Pro II is a 4-in-1 ESC rated 4 x 55A continuous and 4 x 75A burst on 3-6S, running 32-bit BLHeli_32 firmware on a 30.5x30.5 mm mount. It suits 5-inch to 7-inch freestyle, racing and long-range quads on 6S. Choose the Original, or the MCU F3 version, T-Motor's update with a faster processor aimed at demanding race use; both carry the same 55A/75A ratings and a 10V BEC.

Key features

• 10V 2A BEC onboard to power the flight controller, VTX, camera or LEDs.

• Revised heatsink and status LED over the original F55A, with the BEC raised to 2A.

• Protocols: DShot150/300/600/1200 plus Oneshot125, Oneshot42 and Multishot, detected automatically at power-up.

• Damped light mode for regenerative braking and active freewheeling, with tunable anti-desync parameters.

• Beacon function: the ESC beeps after a set time at zero throttle to help find a downed quad.

• Ready-to-fit input lead: 12AWG 130 mm wires with an XT60 pre-soldered, plus a capacitor in the box.
