Features: 1. ARM 32-bit Cortex MCU with BLHeli_32 firmware and working frequency up to 48 MHZ is faster than BLHeli_S. 2. Supporting for Dshot signal at any rate up to Dshot1200. 3. Adopts high quality MOSFET with low resistance and excellent impulse stability. 4. Aluminum alloy heat sink can effectively reduce temperature rising. 5. BLHeli_32 firmware with fast response speed and superior performance. 6. Automatical detection for the throttle signal, supporting for regular 1-2ms pulse width input, for Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multshot (5- 25us). 7. Damped light regenerative braking for higher efficiency and causing very fast motor retardation when the throttle changes from large to small, and enhancing the stability and flexibility. 8. Supports higher KV motor and more power load, and suitable for violent flight of racing quadcopter. 9. The silicone twisted-pair signal cable can effectively reduces the crosstalk caused by signal transmission, offering more stable flight. Specification: Type: ESC Con.
