I'm suspecting a second bad ESC in my build. Are you doing anything special to troubleshoot it to the ESC beside just swapping it out? It was suggested I try a servo tester which sounds like a good idea. What I would really like to be able to do is be able to test the ESC before I start soldering to make sure I'm not the one creating the problems.Hey hey. Bum ESC was the problem. Spent a good day Friday flying the Gremlin around my buddy's house.
