I bought a Tmaxx 3.3 of a friend the other day, it start fine but it will not do wheelies, and i know they put the wheelie bar on it for a reason. I had to richen the fuel mixture because it was bogging down once it shifted into second, i dont know how he has it tuned, it has the TQ Top Qualifier Traxxas Link 2.4 GHz transmitter, the throttle trim knob it turned all the way up. i dont want to just go turning screws on the carburetor without knowing exactly what i need to be turning. Thank you for all your help as i am new to the hobby.
