RE: Hype 3d Rossi 53 do I need a different engine
Since you've got it use it. I've got a Rossi 45 and it's a powerhouse. I'm probably going to get rid of it, not because if's not a good engine, but likes been said, it's heavy. Also it's large (needs a 60 size mount) and it's annoyingly noisy with the mini tuned pipe (I like it but a lot of people complained at several fields).
