Could some one tell me where to buy Go Tech in the US? I don't want to go Ebay as I am pretty sure they sell the series 1. Which I don't want. Also, is the new .28 considered a "sport" engine? I was thinking of trying one out in my Matrix truggy. I am one of those guys who doesn't want to run what everyone elso runs. Around here all you see is V-specs. I currently have Radical mills that no one else runs and they are unbeleivable but I here nothing but good stuff about the Go's.
