Very good item

I fly this ESCs on 180mm drone with 1806 motors.
Power is good, there is no braking, performs ok.
On Oneshot125 i get strange twitching when armed with no throttle.
Price was 1.99 so cant complain.

Not as specs say

May 28, 2018

The specs say it's ATMEGA88, but the chip says Atmega8A -> not the same controller.
I havent flashed these yet, but since the instruction set is different for 88 than 8A one has to be careful to flash correctly.
Oneshot 125 gives odd behaviour of arming by itself and not disarming. PWM only works though.
Might be worth it for you if you are ready to hack a bit with it. =)

These are good esc's for starters!

I wouldnt reccomend them on powerful racing builds, as they won't provide enough power but they are good for beginners and entry level builders.

Bought 12 of these and all of them fail running my mini racers. When I give full throttle quad flips uncontrollable. Tried all firmwares from 13.2 to 14.5, tried all possible combination of settings, nothing helped.
I did tests only with 3S, and they still fail.
