Craig Catto has the first blade from the Mold!! Currently have 223 flight hours. Recently I have been recording a bunch of numbers to give a good comparison between props.
Today I recorded numbers at 10kft, 14kft and 16kft. Numbers are in true airspeed. The order is MPHT, alt, fuel flow, AFR, ECU calculated HP. these are more eco cruise numbers. it is interesting to note that I can still make 180hp at 16kft. Also important to note that I do not maintain this power in level flight as it will easily exceed the VNE. I obey the True air speed VNE of the RV9 and am very cautious of this at High altitude where true airspeed numbers can creep up fast. From some of the Data we have determined that the blades are stalled from adding so much pitch as I go up in altitude so these new blades should give great improvements at altitude.
