We did this last year and they worked great. Unfortunately at the Championship we had to remove one because of a weight problem. We used 4 inch skyway solid wheels and an IR quadrature encoder. The only problem I ever saw with them was wheelies (which we did a lot of), but if you just want a top speed they'd be great.
