Can anyone tell me what numbers Aymar-Demuth used to identify their prop types? I've got one with the composite overlay on my RV that is the 68x72. The serial number, diameter and pitch are written on the data sheet, but that's it. Based on the static RPM on takeoff (2350) and RPM at WOT in cruise (2600) it seems that this might be a climb prop but looking for validation and other info y'all may have.
