Phases/hall sensor wires might have to be swapped. Check this [section](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Firmware-Compatibility#toolbox-troubleshooting) if you have issues.
+Some motors are designed with hall sensors offsetted compared to the phases to generate phase advance. Those motors will then be faster/smoother when spinning in one direction.
