I’m using a chinese dual esc and it worked perfectly fine until one day I went 7 km under heavy rain. The board held up but after some hours the esc was not working correctly, I couldn’t shut the board down and sometimes the motors didn’t spin.
So I opened up the board, dryed everything and good as new( or at least i thought). It kept working for another 2 weeks until one day, one of the motors stoped spinning. I checked it out and the problem comes from the esc.
Did I fry it?
time to upgrade to vesc
If your board isn’t sealed properly you will run into the same issue using VESCs. You know water can damage electronics if they aren’t protected.
