OK.....my turck has been acting wierd lately. i pretty much rebuilt the truck but it sat n my room for about a year. So i dicided to take it out and put a new engine wiht some other things. But anyways. heres my problem i start to run it around and about half way through the tank it will take off kinda good but when its about mid speed and i want to go faster it revs alittle more then it use to. like it doesnt take off right away and peal otu on the dirt or anything. Im thinkin its the diffs. but not really sure. i have a .18 when it use to have a 15 n it so i dont kno.

what kind of truck?

maybe something is slipping like the spur gear or the diff isnt tightened enough?

its on a rc10gt....how can i check if the diff is tight or what??

well, if its like the evader, than there should be a screw that runs through the middle of it from output to output that can be tightened.
