Brian....you just looking to bash or get on the racing scene?.....

I found out what dynamite .21 2 guys at the track are running...its the mach2....and like I said the guy in the expert class that runs one (I remind you this is club racing) is one of the fastest and most consistant drivers on the track...he says its hard to beat em, especially for the money....his son runs a go 5 port and is fast but not as consistant...a guy in the sportsman class is running a novarossi 5 port and actually ran with the big dogs this weekend and took 2nd (best he has drivin since I started racing)...for the most part unless I look at the engine as they go by I really cant see much of a difference...the cheaper dynamite can hit the back doubles just as easy as the other engines if not easier (you havta have pretty good low end to nail em consistantly, they are right after a turn)..also one guy is running a stock losi 8eight 2.0 rtr and he is new...he has been practicing ALOT and it shows...cause he can run around the track really well with his stock engine....

if you want my .02 and your actually wanting to take it to the track...your driving skills is whats going to make ya or break ya....I've personally seen a $115 engine not only run with but beat $200 to $300 engines week after week....really I think you could race the rxb-1 straight outta the box in a beginer class and do well with it...but IMO the stock sport engines arent built as well or with the same quality materials as the higher end engines the companies make....but for beginers class it will get your feet wet and you can see the other engines perform at the track your at to see what everyone runs

I guess you might say that engine preference is just that... a preference....buzz around my track is a go MIGHT get you 5 or 6 gallons...havent asked about the others (ive been looking into the go's)....but I've heard mention that the osvg,s wont get many gallons and the grp's are good long lifers....but yeah...think its more a preference
