well i think 18/49 is the stock gearing that comes w/ the x. Question: why is my sons t-maxx 2.5 w/ upgraded 3.3 seem so much faster on the road than my savage? Is the gearing? weight differance? It seems 2 smoke it on the road,but will admit savage does'nt break nearly or remotely as often as the t maxx. just wondering what seems 2 make a mostly stock t maxx seem so much faster. only thing changed on t maxx is engine,gearing is stock.
