    Great ESCs for 4"

    Posted by Jake on Feb 17th 2018

    These were hooked up to some 1408 3750kv motors and they can spin the Gemfan 4052 triblades on 3S, or HQ V1S 4043 on 4S, without getting hot even on full throttle punch-outs. Max amp draw was just over 22 per motor according to OSD. D-Shot600 is no prob. Nice, tiny little ESCs, I could see them working on any 3" or 4" build really well, they certainly did for me.
