there is all about!
we race here in Holland only at big tracks 265 meters and No problems at all but you have to look for the right gearing.
depend also wich car you use!
and fuel is a point too a little more oil is always good.
thats why run the R&B concept fuel straight out of the can No problemo
don't forget we race these little bombs on 1/8 scale tracks so you have too take care on a few things like fuel and gearing,shifting
