I am not very good at electrical stuff.What do you mean by swap the polariety? switch the black wire for the red? Tried that same thing
Ok kenny if your forward and reverse are OK? Then for example if you have the left motor, and you have the matorro black wire coming from the motor to the heng long board black wire and the motorro red wire to the heng long board red wire? You need to cross them,, Matorro black wire to the heng long red wire and Matorro red wire to the heng long black wire!
