Madison,
As Andrew said, We have been developing a similar drive train, but are wondering how much each of your modules will weigh completed. As is, A completed frame with our currently designed module will weigh about 35-40 lbs, with each module weighing 15 -20 lbs. Is this comparable to yours?
Also, our current design differs from yours in that we will attach the modules directly together using aluminum tube, and that will form our primary Frame. Because of this, our modules had to be somewhat more... Robust, and are going to be made of a thicker plate, probably .20-.25 inch. As soon as we have some renderings we will post them, and thanks for your help in advance
