Of course you can use various motors, that’s one of the key features of the subtractor. And yes, two differentials are needed, I didn’t use the second one just for fun.

Hey, I was just wondering, for the subtractor, do both the motors have to be the same speed/torque? I want to build a subtractor that uses a XL and a M motor–this is because I am limited to these elements at the time. Also, does every subtractor NEED to use two differentials? not that I don’t have two, but I jus wanted to make it more compact.

To think, we used to feel good when we built a lego house. You have taken it to a much higher level. Thanks for sharing.
