I am wondering if anyone has any info on the 2 blade Catto, vs the standard 2 blade metal Sensenich prop on a 9A? I have the 79 pitch metal sensi, placarded for 2600 rpms max, and it seems a little ..well..just not optimal. My indicated airspeed is about 175 or so at 2600, and I do have to pull the throttle back a tad as it will exceed 2600 (160 hp). Climb performance seems a little sluggish, ( from the engine rpm standpoint ) And it takes a long time for the engine to bring it up to speed when leveling out..could be just my perception, as I have not had experience with an airframe with such a wide performance envelope before, admittedly.
Anyway, would like to hear of others experience.
One thing I am awfully happy about however, is the 2350 rpm cruise, at 155 to 160 mph indicated, and 6.7 gph! Not sure I would want to change anything if I had to give that up!
