20A ESC 2-4S

Littlebee 20A ESC is a super compact, lightweight, high performance speed controller for your racing multi-rotor. Pre-flashed with BLheli and ready to use with Oneshot (aka oneshot125 / PWMsync) mode via compatible flight controllers running Cleanflight or similar. Littlebee 20A ESC is using Silabs processor and fast dedicated driver chips, providing excellent freewheeling and exceptional braking capabilities. Littlebee 20A ESCs have all the performance you would hope for and the same tiny size as the DYS BL20A. You will struggle to find a frame small enough to fit these ESCs and they will still give you plenty of headroom on a standard 250 size quad!This ESC allows your motors to respond to throttle decreases much quicker, allowing for more stable flying, and higher response to throttle decreases. These ESCs do not have a BEC, you will need to supply 5v power to your flight controller with a UBEC or stepdown voltage regulator.
