Evo 7260 Radial, what prop for flying?
Fired up the big 260cc radial yesterday.
With a 32x12 prop it exceeds 5k rpm at a little more than half throttle.
That's too much rpm, should stay below about 5k at full throttle.
What's a good prop for flying, it's in a 30% scale BUSA Stearmen.
Maybe a 32x16 or 18?
This is my first big radial and props are not cheap, don't want to just guess.
