View Full Version : my thoughts on the 2.5
07-28-2003, 07:57 AM
admittedly i havent got one, but after reading around here and other places i dont think its very good, it seems to overheat all the time and is hard to tune, yes you have power but reliabilty? thats the question, just what i think

My second one hasn't even come close to overheating after a gallon. It's a little more difficult to tune than other, lesser engines, but the power it has is, to me, definitely worth the little extra time it takes to get it just right.
There have been numerous threads started about who's had good and bad experiences with the 2.5. Use the search feature of the message boards to search this board, the T-maxx board, and the 2.5 TRX board.

searching wouldnt help me give an opinion

Sure it will. Search for your topic and you'll find plenty of opinion on just about anything you can desire.

i thought the same thing when i bought mine. it runs fine though. and so far its been reliable. last time i was out it ran for over 2 hours and only stalled 3 times (once cause it flipped and i didnt get to it fast enough).

I have two of the 2.5's One came with my rustler, and the other I upgraded on my Tmaxx. I did have trouble at first with my rustler getting it tuned right. But I went back to factory settings and retuned and now it's very fast, has tons of lowend punch and stays super cool.
When I upgraded my Tmaxx to the 2.5, it was even easier. I live in Floridq so it stays hot down here in the summer. Granted I had to cut cooling holes in the body.
No complaints here

Dude, Realize that some people are stupid and DO NOT know how to tune. they say it overheats but what do they know, they are just n00bs with RTR cars. I have had my rustler for 4 years and i know that the 2.5 is a totaly wicked engine, and it runs cool and starts up every time, all the time, and dont forget about the power.:wub:

Yeah most of the people with overheating probelms probably didnt watch the DVD or read tha manuel. and thats what they get, a bad performing engine. even if they say oh ive had many nitro engines and i know what im doing. well this engine isnt like other nitro engines, it is a little different to tune and you may have to tune it more often. But from what ive seen people just dont use common sense. I know some people on here have had big problmes with there 2.5's but that could happen to any engine. But with the traxxas plan its easier to get a new one without paying full price. If they dont know how to tune an engine and dont try to learn they are in the wrong hobby.

the 2.5 is an awesome engine, startes every time, good power, easy to tune, it could use a better cooling head, but overheating is rarely a problem, buts thats probably because i know how to tune, unlike most people who would complain.

I will have to defend some people on the 2.5 having problems. True there are some new people that dont know what is going on I admit that. Just I seen way to many people that know what they are doing have trouble with them. The main thing is the carb that caused alot of these problem. There are some issues with the carb design or quality control that needs to be corrected. The 2.5 has the average engine life to be expected with any Asian engine. Run it too hard too often it will die very quickly. I dont think the workmanship or quality is up the the standards that are claimed by Traxxas. Traxxas also calls it a RACING ENGINE yet they dont offer it in the ROAR standard .12 size. If they really want it to be a racing engine why not make it in the allowed displacemt for racing.
