I have a pro .15 or what some call the 1.5 and it's still running. Im not saying that all trx engine are crap. But as wide open has said it's few and far between. My pro .15 has about 6 to 6 1/2 gallons through it and is still running. This engine is about 7 years old and I have just recently run it. But these engine have a history for not to many gallons and having tons of problems. Being finicky and not having a whole lot of power.

Traxxas does make claims that they cannot back up. Believe me, traxxas said the original t-maxx would do 40 mph out of the box. And we all now that it doesnt.

But this whole thread was started about a guy that was bragging about an engine that has 1 gallon through it. The engine is barely broken in yet, and the guy is talking about having no problem's with it. IT'S ONE GALLON. We said to report back when he reach's 5 gallons if he can make it last that long.

Oh yeah and one other thing. Just because the new t-maxx's and revo's are named 2.5 and 3.3 doesnt make the original with the pro .15 the 1.5. If anything it would also be called the 2.5. As the pro .15 is also 2.5 cc's.

Sorry but thats kinda starting to annoy me. Just say you have the original t-maxx with the pro .15. There is no 1.5 t-maxx.
