I'm looking to put a new engine in my t-mass 2.5. I want something that is easy to tune, if its possible. Should i go with the traxxas replacement plan and put a 3.3 in it or is there a better motor out there? Also what fuel do u recomend? I've always ran Top Fuel 20%. I always had a problem with it running hot and burning up plugs. Should I run a content?
