Also, when it comes to machines: there is torque and there is speed. Speed wont have much torque, and its effectiveness is VERY reliant on weight. Pile on just a bit more weight, and effectiveness decreases notably. Torque, though, like a Legion? Take all the weight off, and itll move just about as fast as before. Double the weight, and itll move slightly slower. lots of torque = big engines, big joints.

thats why small and fast stays small and fast, and big and slow will stay big and slow
