Agree with you 100%. I don't know how much "serious" racing I'll be doing. If it's just at the club, I don't think they'll even mind that it has a engine with more displacement. To my understanding the .12 is for ROAR sanctioned events right? I was never clear on this, but the stock 2.5R motor is a .15 making it illegal for racing. Am I wrong?

The 1/10 stadium truck class seems non-existent at the moment. If I could get my car up to spec and performance, my local track said I could race with them truggies. Although I don't know how good I would fair against them. :( Just don't have cash to drop on a new or even used truggy/buggy/1:8 scale. But would love to race. :nod:

If this is the case, I would upgrade to one of the mentioned motors and upgrade to a 250cc tank (direct drop-in). Have seen and heard many Rustlers with stock diffs/trannies and had no problems going with a bigger motor. Obviously not a .28 or anything.

Anyone know if GO has a drop in?

A bigger motor will most likely make you slower on a track. You would probably turn better lap times with a .12cc. It would be basically a Jato with too much power for a 2WD. Interesting for bashing, but not competitive. I doubt that a 250cc tank would fit. The Jato guys have been looking forever for a big tank/150cc tank replacement without success.

A .21 motor will cost about the same as a CRT.5 ARR. Back in the day, had a Jato. CRT.5 was much more fun onroad and off.

Check the Traxxas site for more info.

GO make both a Sport Series .15 and .18 pull start motor that may be better suited to what you are after.

The pics are out of date. These motors now have a blue head and other more up to date refinements on them now.
Contact Runne, he may be able to bring one of these in for you with his next order ??

One of the .21 race motors might be a little much for the transmission you have there.

Great info. I will have to think about this... Also, I made a mistake, it's not a 250cc tank it's a 125cc. My bad. Well I still have my 2.5R (.15) motor and changed my gearing for higher acceleration. My final drive ratio is 11.24. I have superior acceleration but feel that my top end is sacrificing a little too much. So, I'm trying to maintain high acceleration while gaining top speed, which is why I'm looking for a bigger motor. Thoughts please.

Post #298 shows a Ofna .26 in a Rustler.

I know the Jato guys pretty much agreed that for top speed/performance, the OS .18 was pretty much the best, for a stock motor. These little guys don't need the torque, they can use high RPM. Easiest performance increase is to send (or buy) a TRX 3.3 from ABMods. You'll never want anything more.

Just going from a 2.5 to a 3.3 traxxas motor with dual chamber traxxas resonator pipe will already be a big step up. The 3.3 is really that much better than the 2.5. It's got heaps more bottom end and maybe a bit less top end, but you can make up top end with gearing. And also, the 3.3 is easier to tune, and runs cooler than the 2.5.

You can also get the 3.3 from ebay "chop shops" at a decent price.:nod:
That would definitely be the route I'd take.

please no more TRAXASS talk :ha::lol::lol::lol:.....

quixoticboi 10-17-2010 04:07 PM

I want to try a non-Traxxas engine. Don't know if I want to go as big as the Picco .26, but different from Traxxas...
