welp, it runs fine now, or did[>:]. HPI went cheap on me, or on all the rush evo trucks. I fried the grears in the rear in. Come to find out that there wasnt jack (you know the word) in the gear box, well, very little. It got hot and now I have new gears.
I also got new shocks and carbon fiber shock towers, front and rear. Went with a bigger bell housing, 15T and a chevy body for it, now I need gas, broke after all that.
Just check out your rear end for grease, if it came as a RTR truck anyhow. Just hoping Im the only one who has had this prob. Also the hpi web site has tons of hop ups, just need to go to the europian site, not us site.
