Big fins. We did this a few years ago and it really didn't work for anyone. Lot of friction on the string. Often times too much power resulted in twisting reaction on the racer. I am very competitive on PWD. On the Space Derby? It seemed very randomized. I don't know if we had more than about two racers even get to the finish line. This is with a Pack that is extrememly competitive for PWD.

Don't know if that helps. It was fun, however.
