 * Motors are cogging/not running in a smooth way - please try to swap the phases. Usually, color-correct mapping (blue to blue, green to green, yellow to yellow) works fine. However, some hoverboards have a different layout then others, and this might be the reason your motor isn't spinning well
-* In speed mode, wheel are running at maximum speed - find the right mapping for hall sensors, firmware probably measures a speed with opposite sign

 * With hovercar variant in torque mode, braking actually accelerates - find the right mapping for hall sensors, firmware probably measures a speed with opposite sign
 * In general, if you have doubts about you mainboard, please first use sinusoidal control type for your tests, and then use more advanced control type or control mode
