I did unplug the wire. It doesn't matter anymore, I found the problem. :party: A few weeks ago it wouldn't stop raining (after 2 weeks of additional rain) so I went out to drive in a light drizzle. Turns out, the solder on the rx board corroded some. All I had to do was clean it off, and it works good as new now (including the mm esc). Lesson learned, but I'm glad its working now. :yes:

Glad you found the prob. and it didn't cost anything to fix!
