ok yea I have a NTC3 and I've run the Traxxas 2.5 33 % through it... and now I'm runnin Odonnels 25%... Odonnels runs way more smoother than the 2.5 crap... the traxxas fuel makes my car lag in and out once in a while... Odonnels makes my car fly all the time... and it takes more time for the fuel to run out... when I tuned it with the traxxas fuel... could only run it for like 10 minutes... with odonnels... it seem like for ever. lol and I like it...
