Don't know what motor you are running Bro, but if it is a 2.5 then a 28 is about all you can spin. I have tried a 30 on both my 225PM and my 280, I couldn't get the rpm's up with the 30. Maybe somebody's experience is different than mine.
Here my 28p Chopper II. Just back from JC after $175 of clean-up and balance job. You interested?
