And in the case of a roll over / crash where airframes break in to pieces I don't want a fuel tank in close proximity or100LL soaking my cloths. Seems like a very sudden and intense fire to injure the pilot as it did. I hope they can figure out what happened and if they do, Sid, keep us posted.

Re: KR> wheel alignment
Does anyone know of archive information or wish to share regarding wheel alignment for KR tail wheel configurations? Wheels straight, toe in or out? (In level attitude or all wheels down.) And what about camber? How is the handling for width of wheel base vs. length from mains to tail? *Gary * + Width? Generally speaking the wider the better and the more length from mains to tail wheel the better. Toe in or toe out? My experience is neither. Why would I want my tires scuffing and wearing out prematurely. Each school of thought has their theory but I don't accept either over zero toe in / toe out. I want my rudder and tail wheel to handle directional control , not scuffing tires. My KR has excellent ground handling, the tires ride on the center tread, and I get great tire life. Camber? Try to set zero camber using "average" aircraft load, probably 1 occupant and half to full fuel. Setting with tail up or down? I set mine in the near level attitude. That will be the attitude of your greatest ground speed, takeoff and landing, and you'll want the best possible alignment at the greatest ground speed. My KR is 24 inches longer than standard and 8 foot wide mains. That's my setup and I literally forget that I'm flying a tail dragger.

Re: KR> stall speed
At 05:59 PM 1/25/2017, you wrote: What are realistic stall speeds with flaps? Bob R Too many variables, the biggest is your ASI. Actual speed is probably in the 45 to 55 mph range depending on size of wing on your KR and weight. On the first flight, after you get comfortable , go to altitude (your should already be there) , in level flight slowly reduce power to idle and let the plane decelerate. Have the altimeter pegged on a number and hold it perfectly level. As you approach the stall you will probably feel slight buffeting. Note the indicated airspeed when the nose drops and recover. Multiply the read by 1.3 and use that for your approach speed. My KR gives it up at about 55 indicated but it is heavy and shorter then stock wings. Light weight and longer Diehl type wings will be slower. My approach speed with those numbers would be about 72 mph but it feels more comfortable at 80 mph with speed brake full out. I get a bit of extra float and make wheel landings but can easily handle 2500 foot runways. At less than 80 for me with speed brake out it slows rather quickly in the flare and things happen rather quickly from flare to touchdown. I like to settle on like a feather, not like a belly flop at the swimming pool. :-) https://www.youtube.com/watch?v=cgdgxVgPNAk and go to the 2:40 mark of the video.

I once saw a chart that listed the KR2 (original plans built I assume) as close to the F86 in stability based on physical dimension and wing and tail surface area. The closest thing I can relate my KR to (24 inch longer fuselage, standard KR2 tail dimensions) is driving my Buick or Toyota down the interstate at 70 miles per hour. I can change lanes with very little movement of the wheel (much larger than my control stick) with the KR having much lighter control surface push back. If you can drive an automobile at moderate speeds then you can fly a KR and enjoy it, given acceptable C.G. location of course. There is a reason the 2S was lengthened and given more tail area.
