Sorry Chubby, I've listed it in several posts, but I've never figured out how to do a signature (or taken the time anyway). I've got a HiMoto 1/10 scale Syclone Pro with the Japanese Motor and the 2 speed, which I'm replacing with the single speed tranny with HPI clutch bell's (got a few different one's and some different throttle gears to try different ratio's) as well as the Taiwan 2 needle carb...I've also got my son's Traxxas Stadium Maxx with the 2.5, which I have even more problems with than mine...LOL...but I figured I'd spend the money and learn on mine first, then get his set-up...besides, basically all I've heard so far is that 2.5 is a super touchy engine, and we'd be better off putting the direct drop in OS.18 into it (at $200+)...I'd just be better off getting him a redcat after I learn how to get mine right...LOL)
