It seems the B6 is likely a much "higher end" or "better quality" engine and if I were to start racing regularly that would be my pick.......unfotunately there is no 1/8 scale racing at my local track. And I dont have the time to travel 2-3 hours to the nearest nitro races. I miss too many of the 1/10 electric races and they are 5 min from my house!

I picked this buggy up for fun and will be running it on a 1/10 scale SC track just for fun. I doubt I would be able to take advantage of the "better" engine in any way.

I can pick up a new Dynamite Platinum .21 for $110 thats pretty dang cheap verses the $240 plus shipping for the works. I could use the extra $$ to try a pipe or 2 or......other improvements to the buggy.

So I must say for now........money is the determining factor much more so than quality or power.......I am going with the Dynamite to save some cash........and hope that a Nitro class will open up in the future and I can get a little more serious.

Thanks again for all the responses
