Overview ARM 32-bit Cortex MCU with BLHeli_32 firmware,which is faster than BLHeli_S; Dshot signal is supported at any rate up to Dshot1200; Adopting top quality MOSFET,low resistance,excellent impulse stability; Aluminum heat sink effectively slow down the temperature rise.; Full contact soldering pad,more stable soldering. Features ARM 32-bit Cortex MCU, frequency up to 48 MHZ. BLHeli_32 firmware,which is designed for superior functionality and performance. Supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and (5- 25us). The input signal is automatically detected by the ESC upon power up. signal is supported at any rate up to at least Dshot1200. Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling. Supports higher KV motor and more power load, more suitable for flight of racing The silicone twisted-pair of the throttle signal cable effectively reduces the crosstalk caused by and makes more stable. Aluminum heat sink effectively down the temperature rise. Features Con. Current:50A Burst Current (10S):60A LiPo cells:3-6S Weight:10g Size:33x16x6mm Typical Applications:170-450mm Multi Please note these ESCS are NOT CURRENT LIMITING ESCS X-CROSS BL-32 IS USING FLYCOLOR_X_CROSS_BL_32_MULTI FIRMWARE Amp draw demo In this demo, was able to draw 71A with the ESC before the motor dies and ESC remains alive.
