RC 30a Brushed ESC Motor Speed Controller for 1/16 18 24 Car and Boat Tank W/o Brake(Pack of 2 Pcs)

These work great in my fairyweight (150g) combat robot powering n20 gearmotors.The power switch behavior is a little weird, it seems to only control the BEC, so if your receiver is powered by another BEC watch out -- the switch can be off and the motor will still go.However if you're powering your motors via the receiver like I do, with the switch off the LED on the ESC will turn on and dim and everything but the motor won't turn until you turn on the power switch. Took me a while to figure that one out.For what I'm doing I can't use that switch anyway so I just removed it as well as the leads for the battery, which meant I had to short the pads that the switch was on. Easy peasy. Removing those leads really makes the package much smaller too so it's worth doing if you're not gonna use them.

Good for the cars I had over years and wanted to upgrade them great price for the size and quality will order more if necessary. : update they burned up from the 2s batteries not lipo capable

I ordered this item for a robot I built and it worked great. 18 months later I ordered another set but they did not work. The manufactor went above and beyond to help me fix the problem even sending me a new set of controllers for free. Turns out the problem was my fault as I ordered the wrong part. They were willing to send me a correct set again for free. I build robots as a hobby and will certainly buy from this manufacture again.

Update:They kindly sent a replacement and it works fine.————Got erratic and unpredictable behavior from the first one. Swapped in the second one and everything was fine. Not ideal and kind of a waste. Seems a common problem, unfortunately.

These are ready to go and pair nice with a receiver out of the box. Set up for tank style drive train.
