The only issue I had with mine was that the MODE button didn't work at all. Everything was plugged in and was able to program the transmitter and it would run. But I couldn't get into any modes. It is like it wasn't even soldered to the board or something. I should get my replacement by tomorrow.
Anyways.. i hear that the "glitching" thing was people free wheeling it at the bench which is something that you are not supposed to do with the timing advanced escs. They are designed and timed to work under Load conditions only. But hey, I wasn't there and I'm sure there are many different stories, but there were a few that were working ok. So I guess we have to wait for Sean or Burito to explain.
