I know where to find the right gearboxes. I don't have the money to just buy 78 dollars in gearboxes though. I am going to find a way to make these work. What I need to know is the correct turn value for the motors in order to make these gearboxes work so if anyone makes the same mistake as me, then they would just have to buy different motors. What I should say is, I have 5:1 ratio GB, High Torque motor or High Speed.
