I have a 2 week old T-maxx 3.3, just getting into the hobbyI've been trying to tune my engine. when I hit the throttle it takes off slow then goes. When it gets to a certain speed when the transmission should shift to 2nd gear it doesn't. Can ayone help?

Sounds to me like the engine is still running rich. Did you break it in just like the instructions say. After break in the engine is running real rich and needs to be leaned in a bit. I have the 2.5r and after breakin it was running too rich to shift. I know this page is about the 2.5 but it will give you some idea on how to adjust the carb.http://www.traxxas.com/support/index...l&cat=34&id=92
