hello, about a month ago i bought an xtm xt2, its my first ever rc car, and to say i dont know a great deal about them would be an understatement. i went through the whole break in process and had quite a lot teething problems with i think are sorted now. the trouble is, i dont think it goes anywhere near as fast as it should. i had bit of a race with a friend of mine, who has a nitro which is supposed to have a max speed of 30mph and he won, albeit, not by much.but according to the review by this site the xt2 was clocked at 44 mph. ive also seen videos on the internet where they seem to go faster than mine. i know mine is probably not tuned perfectly, but i also know that tuning it is not going to get an extra 50% speed out of it.
I'm willing to bet your motor is rich. How much smoke comes out of the exhaust at high RPM? What does it sounds like?
