Someone asked the question "What makes a pant a PR type?" TO be totally honest, I am not 100% sure, but I believe it has to do with how much of the boundary layer stays attached along the length of the pant. The longer it stays attached, obviously the more efficient, and the more pressure you can recover from it, I suppose.
We had a warning down here late last year I think it was, about IvoProps throwing blades. Admittedly they were used on 2 strokes (582's) with reduction gearboxes, however, to me that suggests using them on a direct-drive engine is even more dangerous as you don't have the gearbox to absorb power pulses. A Kitplanes article last year also had a good spiel on fairing in various parts of the airframe. In the example given, they faired in one of those square GPS antennas. Might be worth a look if you have protrusions like that on your KR's. Cheers, Rob Robin Wills Second Person, Pacific National KR-2 19-4594, Ser# N111 [email protected]
