If your feeling really cheap though, you can just use the standard X chassis, and remove some material from underneath the where the flipped pulleys sit
The LP is a little on the stiff side, the stock chassis is better on most tracks.
If I had my belt flipping time over again I would just dremel the stock chassis, the lipo conversion really wasn't worth the $$'s
