no they dont do 50 stock and the ebay this is a misprint (himoto admited it themselvs) rc driver tested the himoto rapida pro which is the sam just an on road version and it did 42mph. yeah thats a great setup, but i still think that u would be doing awesome to hit 55, but hey thats faster than any stock 1/10th except for the 3.3s and the cen onroad car.
