RE: prop suggestion?
I think what some of use are trying to note here...
... there is a wealth of bench and flight and historical performance data on the Mag 32 and Mag 36 engines specifically .... and general engine experience.... which we are trying to share.
The point of someone posting a question similar to this original post in this forum I would imagine would be to harvest some of that data and experience, in the form of a prop recommendation. Avoid re-inventing the wheel or making similar mistakes other can caution against, while at the same time optimizing the performance for the intended application.
The original information on the manufacturer specifying a 13,000 rpm target in the manual was not accurate.
