1PCS Mini RC 20A Brushed ESC Motor Speed RC ESC 2KHz Forward Reverse Brush Brake RC 2S for Controller Boat RC Car Tank

For the price these are great. Video shows a test setup, the pololu motor drivers I was using with a seeeduino didn't work right. It's only driving an N20 gear motor with 500ma stall (and I didn't try stalling them) but these should be fine for 3 or 4 amps, the mosfets look fairly beefy. I doubt these would be any good anywhere near 20 amps, especially without a heatsink. But for how dirt cheap these are, and the relatively small form factor, these should make great motor controllers for n20 and 130 dc motors. If I get a finished project working I will try and remember to upload another video. The back of the board does have M+ and M- labeled, they are the center connectors, the outer ones are the battery. I tested all 4 just like the one in the video and all 4 work.

Awesome ESE's. They work perfectly for what I'm using them for. they seem good quality, And remarkably good for they're price. Highly recommend.

They work, super cheap. But they do not handle 3s voltage like the listing says. Pull too much current and the BEC browns out as well. But they work perfect for restoring old New Bright Rc cars which is what I intended them for. My son was so happy to have matching monster trucks to play with. The ones in my video are nearly 20 years old!! So naturally cant get replacement parts.

Works good! installed it on rc boat project. Started right up. No issues

Love these esc. Small enough to make anything an RC :) perfect for your small projects!

This ESC is is junk. I was not able to get it to work. I have been building rc and robotic equipment for about 25 years. This is an absolute disappointment. I would give it zero stars if i could

Was looking for an ESC that supported reverse for upgrading the motor in an RC car so I needed it to be able to drive the motor forward and reverse from the transmitter. This works great.

Perfect size for the job

Fantastic escs

Muy compacto y funcional
