Indeed, I thought it was 720, but I had it working after that, before I went home... It'll be fine though, it'll just mean I upgrade to brushless a little quicker! I'm sure it'll be nothing major, there's no reason for it to have blown, I'm fairly sure it'll be something and nothing but if not it'll be alright, I'm only using them for HardWired I I think now, 2 and 3 will both be brushless
