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

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.

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.

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

This is my first ESC ever, with that said, it was pretty simple to get going. You need a basic knowledge of how an ESC works as there are no instructions. If you buy these pay attention to the picture of the connections. UPDATE: after some testing and further research, i have found that these ESC's have a Battery Eliminator Circuit built in. The pigtail for GND, 5V, and SIGNAL is misleading. the 5V line is an OUTPUT. Unfortunately after making my purchase I realized that these ESCs will not work with my 12v rover project. They were cheap enough to just keep for a future project. Only rate 4 stars because there were no instructions. The screen shot of the sketch is what the video demonstrates. Adjust the throttle min/max values, the sketch is a quick and simple test. The neutral value is correct and the ESC will only arm at the neutral value.

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.

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

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

Perfect size for the job

Fantastic escs
