I took quite a few pictures...so many that it will take a while to sort them out and turn them into a web page, but I'll try to get that done in the next few days. As for awards, they were mostly split between Jeff Scott and Kim Niebauer, although there are definitely some honorable mentions, such as Roger Bulla's newly minted plane. They were all very close in terms of quality. I also got air-to-air shots of all the KRs visiting (except for Mike's...he was not around for that), and we owe John Bouyea for that photo opportunity. It was a well-done Gathering. Many thanks to Dan and John for pulling off a great Gathering. I haven't done anything regarding the Gathering photos because we've been riding around Oregon and Washington national parks for the last week, ending up with Mt St. Helens "national monument" yesterday. That was quite interesting. It had recovered amazingly well from the photos I remember from the news way back in 1980...just gray moonscape with zillions of tree trunks laid out like match sticks...all pointing away from the blast zone. It looks a lot better now, and it's good to see how nature manages to recover from that kind of event. More on that (much later) when I do a web page on that vacation...

KR> ADS-B
Hey Guys, I've been working off and on adding ADS-B to N357CJ. It is a struggle to get all the antennas in locations inside our fuselage. 5 on the ADS-B, the transponder, gps receiver, cam antenna and the ELT all trying to be in the same area. I think that I have it but it isn't tested out yet in flight. but at least it is all programmed and everything lights up and shows that it is talking to the gps. Joe Horton Coopersburg, PA.
KR> KR Stuff Misc
Just some random info that some Netters might find interesting. The Revmaster 2100D built from 1968 to 1989 was rated at 65 HP, at either 3200 or 3400 - certainly not at 4200. The efficiency of KR-size props deteriorates rapidly when turned much beyond 3100 RPM. Steve Bennett rates his 2180 at 76 HP at 3400 at sea level. The reason I mention "sea level" is that if you take that same engine up to 12 thousand feet and turn it at 3400 it's putting out between 40 and 50 HP, depending on what formula used. Rule of thumb is 3% loss per thousand feet. Perhaps more accurate is altitude x 0.03 x HP/1000 = In my own instance I run the engine WOT at 3100, not 3400 (RPM is a function of prop pitch and diameter when running WOT of course) so at my normal altitudes of 12.5 and 13.5 I'm pulling 40 hp or less. No wonder my cylinder and oil temps remain low and fuel efficiency high - between 3 and 3.5 GPH at those altitudes. The original R-2100D engines, the ones built before 1989, came with cast cranks. Although I don't think I've ever heard of crank failures in the early engines (surely there must have been some though), we don't want to use cast cranks in a VW installed in an aircraft.My first KR-2 had the 2100D with the cast crank and the Maloof CS prop that Revmaster sold at the time. I never had a problem with either one but wouldn't recommend them. * PatS in Mississippi mentions he has two unfinished KR's and an unfinished Lancair for sale. Pat was evidently following the natural evolution of the KR design. Lance Neibauer built a KR-2, N282L last seen in San Antonio and owned by someone named Anthony Lee. I think I recall Lance raced it back in the day and got over 200 MPH with the Revmaster 2100D he had in it. He then went on to design his gorgeous Lancair based upon what he had learned building the KR, as told in this interview: https://www.youtube.com/watch?v=qrwm82HlKiA He mentions that he consulted with Northrup engineers but doesn't mention Ken Rand by name. Ken worked for Douglas but Douglas and Northrup were both in SoCal and were closely associated from their very beginnings. Jack Douglas and Jack Northrup came to SoCal together and worked closely together so to say one consulted with Northrup engineers is to say Douglas engineers as well. Located in El Segundo and Hawthorne, communities next door to each other, these companies were twins joined at the hip. Lance lived in Redondo Beach, right next door to the above communities. He formed Lancair at first in a hangar at Santa Paula (SZP) before moving to Bend, OR. Mira Slovak (friend of Sparky's) flew out of SZP in those days, as well as Steve McQueen. For such a small airport it has been home to many important people in aviation. The first Sunday of every month they have "Open Hangar Day" and for anyone visiting the LA area and can time your visit to the first Sunday of the month, visiting SZP is well worth it. Sparky once had a hangar next to John Thorp at Whiteman Airport and in his life has met just about everybody of note in antique and homebuilt aviation. He flew with Ken Rand of course. He's a walking encyclopedia and it's been my good fortune to have known him since the early 80's and currently have a hangar three doors down from him. He gave me my first ride in a KR and there's a whole bunch of other people who can say the same thing. I've had many, many people ask me in my travels over the years, when they find out I'm from San Diego, "Do you know Sparky? He gave me my first ride in a KR!" I can't tell you how many times this has happened . . . dozens. I could be and probably am totally incorrect in my assumption of any personal association between Lance and Ken. Ken died in January 1979 and Lance finished his KR in 1982 after a one-year build time. My thought is that the Lancair is truly the next generation KR, not the KR-100. The latter was simply a lightly modified KR-2 with a bigger engine & different airfoil - similar to Mark Langford's plane. The Lancair was an evolutionary leap. We had the pleasure of meeting Kim Neibauer at this year's Gathering in McMinnville. Kim is Lance's cousin and flew his really nice looking KR-2 (I mistook it for Joe Horton's plane at first) to McMinnville from Grand Junction, CO. I really wish somebody would publish an overview of this year's Gathering - who attended, who won what awards, pictures. I saw plenty of cameras there but so far I haven't seen any results of what surely is a treasure trove of photographs. Jeff and I have posted our travel pictures, plus some non-annotated Gathering pictures taken by Jeff, but what is still missing is a photographic and general description of the Gathering itself - you know, like we usually see following a Gathering. We need another Video Bob of course. Lacking such a person, it would be nice if those who took pictures this Gathering would publish their photos and an account of their experiences

Good morning Pat,Yes, i would be interested. Can you give me?The status of the KRs? Who built them? Wht stages are they in? And maybe pictures and a ballpark ?figure on price?Again, thank you very much for the reply!Bill Jacobs -- Original message--From: PatS via KRnet Date: Sat, Sep 12, 2015 10:35 PMTo: billjacobs386 at yahoo.com via KRnet;Cc: PatS;Subject:KR> KR stufBill: My name is Pat shows, I live just north of Hattiesburg MS.

KR> KR2 Performance example
Just for comparison, I have a friend here with a tidy classic KR2 with the original retracts. It has a Revmaster 2100 on it rated at 75HP (maybe at 4200rpm, but max rpm on T/O is 3300 rpm, so probably 55hp) Basic weight is 625# at the moment and with full fuel (95#) and Pilot(145#) his usual MMTOW is a smidge under 900#. He has the older aerofoil too so I think this is quite representative of that model. I didn't get his fuel burn but I remember doing an exercise converting the 55HP back to FF using BSFC and it worked out to be close to what would be expected, around 4G/H. At 25'C he can climb at 900'/m and normal cruise 138m/h.(120kts). Paul. = colin hales via KRnet wrote: does anyone own or seen a bare bones 2180 powered Kr to try it? Who is the lightest Kr pilot by the way? I know a guy who must be only 165lb. I can only confer with what I know, which is my Jabiru 2.2 Kr2, 75 hp. It drinks 26 litres at full power 6.5 us. My best cruise figures are at 18 litres 4.5 us per hour, so my cruise is still actually quite high at around 70%, at 120 mph. My kr only weighs 540 lb empty due mostly to the light engine and no flaps or speed brakes or interior trim . All take off performance figures are at max gross anyway, well in my book and every other certified aircraft book they are. So at 900 lb (published MAUW)
