@HCWH97 You should do a bit of reading on the forum about the VESC. So there are three variants of the VESC: 4.12, FOCBOX(VESCX) and the VESC 6.4. The shittiest is the VESC 4.12- there are plenty of vendors around and these are mainly china produced, have limited watt output on 6s, and tend to be the least reliable and some cant even run FOC, also they tend to let the magic smoke out close to 60,000eprm. The FOCBOX is great, it solves the issues of the 4.12 with bigger watt output(heatsink) and new mosfets that raise the 60,000erpm limit, they also run foc reliably. The 6.4 is the VESC 6, the best and last iteration of the VESC which eliminates the erpm worry, and is also more reliable in FOC, best watt output but they are quite pricey.
