Questions About 200A (or more) Brushless ESCs

[TechAUmNu]

These are the modified VESC's designed by Rory Mangles of Team Nuts; uprated FETs, Caps and a variety of other tweaks that I can't remember. We are also only driving around 60Kg max on hours which probably helps even if the motors a 3770W Continuous.

Yeah that's the ones I blew the DRV chip on three of them. Managed to replace one but we switched to the VESC-X and haven't had a single problem with them. Even at 80A 8s with 80,000 erpm

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.
