    OK, I've heard about 2.5's, .15's, .25's, could someone tell me about what all that stuff means? I know a .25 is better than a .15, but what about a 2.5, ect.... thanks

    really .15 and 2.5 really are the same number just in different units it just has 2.5 to make it seem like it would be huge and really good. all it is is just basically an upgrade from the .15

    dude what are you smoking? they are talking about engine block size not horsepower and all that #@$% . its .15 ci(cubic inches) and 2.5 cc(cubic centimeters). atc your talking about the trx engines.but they i think they mean all the companies. they all make .15 but traxxas calles it a 2.5 so people think it is bigger.well it is bigger.a bigger pain

    ya. thats a nice engine. i would like to race a wasp .18 against it

    keep in mind that the Wasp .18 is rated at 1.9 hp your not gonna find to many motors that are rated at that hp in the small block . Plus the price under 90. what a steal. I'd still like to see one of those P2 in one of my Maxxes.

    ya i havn't even seen anyone with one in there maxx yet. all the people have the .21 conversion. i think the motor is well worth it. so much easier then the conversion and less expensive

    well I might have to breakdown and get a P2, the thing is that I have 3 of the 2.5 motors that I change out on my Maxxes, Lots of money invested in those motors. I've got a total of 8 motors already.

    I've got 3-2.5's, 3-CVR.12's, 1-Wasp .18, and the stock AE.15 that came with my RC10 GT. I also have about 15 Electric motors that I run in my TC3,B4,T3. so you could say that I'm really busy .
