Les I think your idea of enlarging the indoor track is awesome.An outdoor track would be sweet as long as you can put a roof over it.LOL.As for the E-buggies on the indoor track.Yes as far as weight and size they are close to 4wd Sc but the SC are not run on 4-6 cell lipo's either.I am all for a bigger track.On the fence about e-buggy indoors though.Just my opinion.Boy this weekend is going to suck with no place to race.Damn mother nature.
