RPM Change
 
I'm looking for a general idea on how many RPM Change there would be using bravo 1 4 blade props going from lets say a 28 to a 30 to a 32 would your say 300rpm per each? stock props no special Lab stuff.

It will worsen as you step up..as you start to lug the engine with every increase. I use a 250 rpm but I would consult B Blades. Possible they still have a testing program if your ready.

There is about a 200 rpm change for every inch of pitch change using the same model of prop.
