Gorgeous day here in the Southwest today. That gave me an opportunity to do some performance testing with the new prop on my KR.
Many builders ask for performance numbers on different KRs, so below is a set of numbers I ran this morning while documenting the performance with the new prop. Rate of climb was pretty good, still showing 200+ fpm at 15,500'. As long as I was at that altitude, I ran a series of 4 direction runs recording the gps data and rpm at 1000' intervals down through 8500'. I'm still trying to sort out the changes to the performance with the new prop and decide whether to order a different prop. I saw the following results this morning: Altitude MPH Knots RPM 15,500 147.5 128.1 2500 14,500 152.25 132.3 2525 13,500 154.0 134.0 2550 12,500 154.75 134.5 2600 11,500 157.75 137.0 2650 10,500 159.25 138.4 2650 9500 160.75 139.7 2675 8500 163.75 142.3 2700 Unfortunately, I can't test any lower due to the local terrain. Oh yes, and it's a beautiful view from up over the mountains. :o) Jeff Scott N1213W
