Just a quick report back, first full pack(s) through it on a local playing field with a jump or two. Behaves brilliantly, nothing broke or fell off, kinda pleased with that. Got around 30mins, quite a bit on full throttle. Wheelies on command even at speed, quick pulse and up it goes. Have to build up speed slowly, if you gun it, it just flips over backwards. Braking is way too powerful, flips forward over itself half a dozen times.
On the ESC, lvc is set to 3.2v, cell voltages all at or slightly below 3.2v once it cut in. It only did that once, a reset turn on/off got a couple of seconds then lvc cut in again. So working as it should.
Oh, and the ESC, motor are barely warm to the touch as you'd expect really with the gearing. I don't think I'll be gearing it any higher. It's plenty fast enough if overpowered. Its fun that way and more a matter of throttle control than actually having too much power. Overall it's a lot of fun and the center diff does help lay the power down nicely. The shell is already cracked in three places, won't last more than a few sessions, so looking at fitting a Summit shell with exo-cage.
