They can be made to run pretty well, IMHO.  We run a front motor class, and many of the cars are on a par with inline, or even sidewinder cars.  It take a little fiddling, weight in the right places, and usually a change of gears(and rear axle).  The tracks I run on have individual power supply's, so cranking up the voltage helps too!  Have fun experimenting, it IS a hobby after all!
