ESC-HB-20A520053

A BLHeli S 20A ESC designed for use with Holybro's 2216-880KV Motor / X500 Quadcopter Kit. The ESC is slim so can fit within 16MM booms and it comes with long wires and pre-soldered 2MM bullet connectors for a quick and easy installation.

Main features

● EFM8BB21F16G MCU, pipelined 8-bit C8051 core with 50 MHz maximum operating frequency.
● Dedicated high frequency driver, makes the start more smooth. ESC maximum speed is 500k eRPM.
● BLHeli-S firmware is designed for superior performance in multirotors, and uses hardware generated motor pwm for smooth throttle response and silent operation.
● Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.
● Supports higher KV motor and more power load.
● The code supports regular 1-2ms pulse width PWM input, as well as Oneshot and Multshot . The input signal is automatically detected by the ESC upon power up.
● Supports Dshot150, Dshot300 and Dshot600. Dshot is digital signal, anti-interference ability is stronger and do not need throttle calibration.
● The silicone twisted-pair of the throttle signal cable reduces the crosstalk caused by signal transmission and makes flight more stable.

  • Con. Current:20A
  • Burst Current(10S):30A
  • BEC:NO

UK Express Shipping - Next Day Delivery on orders placed before 4pm


COVID-19: We are still shipping out orders daily, but have changed our same day shipping cut-off time to 1PM to help cope with demand. If an order is placed after 1PM we will still do our best to ship same day as our daily postal collection is around 4:15.

Please be aware that deliveries with Royal Mail are taking longer to get through. At the moment we are finding it can range from next day to even up to two weeks, with 3-5 days being typical. So if you choose Royal Mail as a shipping method please be patient, shipments aren’t going missing they are just taking a while to get through the postal service. For fast deliveries we recommend choosing DHL.
