Whats everyone think of the sterba props? I'm building a 6 with a io320 that's suppose to be 180hp. and thinking of trying a sreba prop.
Catto is constantly improving the props. The current racing configuration Catto MAY be as much as 7 knots faster than Catto's previous best and probably 15 knots plus faster than a Sterba.
The extra performance of the Catto will eventually pay for itself if you fly enough, especially if you are in the high terrain and routinely make long climbs to cruise altitude.
Also my current Sterba has some mild vibration that should not be there with a wood prop.
