Sorry no one is answering your post. I am not sure but i just did some research and bought one for my cen mt2 and i was reading that it is a direct drop in for the old .15 Tmaxx but not for the new 2.5. Also you have to check becasue there are 2 .18cv-rx one has an s on the end and it means it has a longer shaft. Make sure you checkbefore you buy
