We were at 80A, 12S, 80'000 ERPM on the MVESC's. I think the weight makes a difference (60kg not 110 as mentioned before), and the quality of the Scorpions could play a factor too. I would be willing to bet there is some significant variation in the consistency of a Rotomax and other cheaper motors. They may pack a lot of power but i think that is partly their undoing when it comes to being drive motors. I have no evidence as such to back that up, purely anecdotal, but it was a dodgy Rotomax that kept killing Pulsars VESC's.
