Actually i think it would create a more smooth ride. It would put less stress on the tubular steel. With the scaled down model we made, this design was able to withstand a speed 142% of the previous design. Also there was less resistance. The track we used was starting to fatigue faster with the old design compared to the new one.
As far as the heat problem, the enclosure can be changed to accomodate certain problems.
