So unless you have those two additional pieces in your pocket you can't build a KR1-B and thumb your nose at the FAA while flying with out a medical (how every satisfying that might be). http://www.sonex-ltd.com/motorglider_definition.html Take it for what it's worth.

Did you convert IAS to TAS before comparing with your GPS? If not your results will vary dependent on altitude, QNH and temperature. Difference between TAS and GPS is essentially the wind component. It's been so bloody hot and low pressure in Aussie lately that at sea level I've been recording a density height of 4500feet....makes a big difference (say 15 knots) to TAS calcs and to engine performance.

That was the extent of my conversion. Then I'd look back out the window and see the landscape flying by and grin real big. :-) I replaced my oil quick drain yesterday with a plug to see if that takes care of the oil on the belly. I don't work till mid afternoon and we have a great day with clear skies and 0 wind so I'm going to try to get two or three hours on the KR. I'll see if I can work up the nerve to try those slips again and get a better idea of what's going on there. I think I'll do some testing with the speed brake and try to get some numbers on that also.

Are you applying back pressure and raising the nose any during the slip? A combination of slip and nose high pitch can produce a momentary loss of rudder authority. Though not a prevalent event, it can occur. A good way to determine if this is present is at the moment of wing drop, see if there is a momentary corresponding yaw opposite of rudder deflection. It probably is not there as this usually happens at a very high uncoordinated pitch angle and then it has to be the right combination of fuselage design, rudder size, speed, etc. etc. Dana Overall 1999 & 2000 National KR Gathering host Richmond, KY i39 RV-7 slider, Imron black, "Black Magic" Finish kit 13B Rotary.

The KR1B Motorglider numbers that Virge cited of 484 empty weight and 27' wing span yield .66, which is higher than .62. I guess if you want to build a KR1B and call it a legal motorglider, you've got to either make it weigh less (doubtful!), or extend the wingtips another 6" on each end, and you'd be at .62. Sounds interesting...

I went to talk to a person whose name I have misplaced, = but he is the owner of Sky King Aviation at Chandler Field in Mesa, AZ, = and is an instructor, flies anything multi-engine, jet, Bonanza, RV, = Lancair, and many others and says the most interesting, most fun and = neatest of them all is the KR!!!!. BUT--he was ferrying one to = Maryland, packed in with his Father, when, in cruise, he noticed the = ball over to one side, so he applied right rudder, the ball went to the = corner, he pressed harder on the rudder and the plane pitched down so = violently that he hit his head on the canopy-the more rudder, the worse = it became. Not knowing what was happening, he let go of all controls and = the plane recovered immediately, and in so doing noticed that his foot = had slipped over on the LEFT rudder pedal on the pasenger side, so he = was pressing left when he wanted to use right and thought he WAS using = right. His explanation was that in cruise the KR is trying to fly tail = high and the HS is therefore holding the tail down , but when he swung = the plane sideways, the HS must have gotten blanked out so that it was = no longer holding the tail down so up it went! And he is pretty sure = of his diagnosis. If this had happened at a low altitude, he would have = bought the farm. So a slip, at least a strong one , could be dangerous = on approach, since Larry is experiencing exactly the same thing. The = two descriptions of the circumstances and the plane's reaction are = strikingly similar. If you would like to talk to this man about it he = said he knew Lee Van Dyke of Mesa and that might be a way to contact = him. I apologise for bothering you directly but I think this could be = important.
