I did see where anyone mentioned this, if you have, sorry to repeat but your title says that you have a T-maxx .15. If that is true and it currently has the Pro .15 engine then you will also need to buy the conversion kit for the 3.3 throttle linkage. The Pro .15 is a rotary carb, while the Trx 3.3 has a slide carb and the linkages are totally different.
good lookin out jp! thanx
