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

Buenísimo,le metí 12v 5 amp y los aguanto esta perfecto y barato.

The media could not be loaded. 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.

These are great and work as advertised

The media could not be loaded. 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.

This is a very good brushed ESC small for smaller RC projects. Works fine, it has a Quality Control sticker which is very important.

I used this as a cheaper option ESC to build WPL RCs. Works as it should be.

Hobbyist. Works well Thanks.

Update: I used a different controller and I have the braking working, honestly don't understand if its the different controller, but I now have braking. The ESC does have forward and reverse, but I still wish there was a bit more information for the switch on the ESC. I moved my rating from two star to 3 starGlad that I ordered 4 of them. Got the third one to work, the other two appear to have blown the power to the motor. Servo control worked, but the motor stopped after two or three trigger pulls. DOES NOT APPEAR TO HAVE BRAKING!!!! Flipped the little switch, and it didn't appear to slow down the RC motorcycle at all. Meh...Max Current from power supply was 2.4AThis was running the Kyosho Hang On Rider RC motorcycle. The third ESC is working fine, but there is not braking no matter what I tried to do with trip on the controller or selecting the dip-switch.Seller: Tell people the function of the dip switch and the direction of settings. More information is better.
