Anyone done something like this ?

Our Ultimate Ascent drive was like this. You should put the drive wheels on the end which is nearer the center of gravity for best traction and general performance. We had ours on the front, because we were front-heavy that year. Even then, when we tried to do a sprint, we found that we had much better control in reverse because the acceleration moves the weight towards the rear tires (as you're moving). So if your weight is centered, you will have better acceleration and control as you move forward. Unfortunately, you then give up braking traction, unless you figure out a way to brake the free-wheeling omnis.
