Most of my flying has been in the PHX area, and your story brings back some great memories. I saw my first KR at an airshow (not Copperstate, though) at Williams when I met Howard Kaiser, who also got me interested in EAA. Then my wife pointed out that I didn't know how to fly and followed up with a gift of flying lessons at Glendale. Hope you have a great flying season.

When the hot dogs and roasted corn were gone and it was time to leave, one of the good follows from the chapter asked how I intended to leave with only half a tail wheel. It appeared that at some point in my journey the tail wheel bearings quit and my wheel had been ground in half. After unsuccessfully looking for an hour for a sacrificial shopping cart, I decided to continue my flight home to Michigan. I explained to the puzzled onlooker that if I had taxied in without knowing the tail wheel had failed, that I could continue in the same condition. At that point I hopped in and taxied out using differential braking and forward pressure on the stick to keep the weight off the tail. Over the years I have found that it is not as important that I fly a taildragger or a nose wheel aircraft, but what is most important is that I learn and practice which ever one I use, so that I am safe. Be safe and finish those KR's. I ordered a new cam from GPASC yesterday.

Were any of the changes based on KR flying experience (larger rudder?) I am looking fwd to reading the flight reports. Good luck Steve Jacobs Zambia ------------------------------------------------------------ Steve, et al, The changes I incorporated into the plane are based on my opinions of what would improve the plane to bset suit me. That doesn't mean they are either right or wrong, but are more of an experiment. Yes, they are based on 520 hours of flight time in this plane. First let's start with a description of what my plane really is. I call mine a KR-2S; however, the plane was started prior to the release of the -2S supplements to the plans so doesn't have all of the mods incorporated. In essence, it was a stock plans built KR-2 with an extra 14" bay in the aft fuselage, then the KR-2S top deck and dragonfly canopy installed as they were available when the airframe was ready for the top deck. On the first flight 8 years ago, I discovered that the horizontal stab had been mounted at the wrong incidence. If you have seen photos of my plane, it had huge trim wedges glued on under the trailing edge of the elevator to make it trim up correctly. That is a significant amount of drag, and asthetically ugly. I could blame the guy that started the project for the incidence, but then I didn't catch it until the first flight either. I know there are lots of opinions, but I have always felt that the elevator didn't provide enough feedback to the pilot. I never had a problem with it, but the thought of letting one of my friends fly this plane or selling it to someone else scares me. I want to make the plane easier to fly, but still preserve the sporty responsiveness. Again, there are other opinions, but I have also always felt that the horizontal stab didn't provide sufficient stability for the plane. I didn't care to make map folding into an aerobatic experience. Responsive planes don't have to be unstable. That makes three strikes against the elevator and horizontal stab, so I wanted to built it all new. Based on some research from the NACA reports and ASE papers from the 1930s when the government was paying for a lot of engineering research and wind tunnel testing on planes in the performance range of ours, I decided to install some rather large wing root fairings to help clean up the air flow at the wing root. While looking at that, I figured that if I was ever going to install flaps, I should do it before I build the fairings. The question has been posed, "Why flaps instead of a belly board like everyone else?" The short answer is that I rarely do what everyone else does. Additionally, I didn't want to build fairings on the belly to fair in the belly board when it is retracted. Also, my KR was built with the aileron bellcranks in front of the rear spar, so I could hinge my flaps almost right at the rear spar. Consequently, my flaps are 11 1/2" x 25" per side, which is significantly larger than the stock KR flaps and is comparable, or even larger, than the belly boards. When retracted, the flaps retract cleanly into the bottom of the wing root fairing. More on the elevator/horizontal stab: It has always been my opinion that the plane would benefit from a higher aspect ratio horizontal stab and elevator and significantly more stab area. I borrowed the stab/elevator drawings from Mark Langford's web page, then built it with a span of 8 feet. I chose that number by creating the same ratio of tail volume to wing as the Tomahawk sitting in the same hanger. With the short tail moment, that would still leave the KR on the low end for static margin, but in my opinion, should provide a big improvement to the problems as outlined above. While building the tail, I chose to borrow another design feature from my Tomahawk and eliminated the trim tab. Instead, I chose to add in a set of biasing springs just aft of the baggage compartment. My KR has pushrods for the elevator and a bellcrank at that position, so it was easily added in. The biasing springs are operated using the same MAC trim servo that used to be mounted in the tail. I'll push a couple of photos of that to a web page when I have time. My KR has a small strake on the front of the vertical stab. That strake seems to have a significant impact on the way the plane flies and makes it tends to make it slip rather poorly in my opinion and makes crosswinds more difficult than they should be. It also used to blank out one side of the elevator while slipping so the nose would bob up and down throughout the slip. Not uncontrollable, but also not right. The larger rudder is designed to make it easier to land in a crosswind and easier to slip, which should also work better with the significantly larger horizontal stab and elevator. I did get the plane out for a short flight last night. This flight was only about learning the plane's new flight characteristics well enough to safely land it again. I must say, the flaps are wonderful and make this plane so much easier to land. I have some tuning to do with the trim and stick position, but that should be only minor in nature. I should get to do some more testing on Friday. Thanks to Oscar Z for running the air load numbers on the flaps for me as well as acting as a sounding board for my ideas and to Mark Langford for making the horizontal stab/elevator drawings available. One last note on the changes. The plane still has to get a leading edge wing root fairing, cuffs for the wheel pants, cuffs for the gear leg to wing juncture, new exhaust designed and built, and a number of modifications to the cowling. I'm still contemplating changes to the tailwheel and how to fair the tailwheel, but haven't made any decisions yet. Since the FAA only gave me a 5 hour test period, it is possible that it might make it to Copperstate yet this year, although still in a very much unfinished state. OK. I'm sure I'll see plenty of flames about my opinions, so fire away. Best regards, Jeff Scott N1213W ------------------------------ Message: 17 Date: Thu, 22 Sep 2005 10:02:35 -0500 From: "L. D.

Power to weight ratio? Added work to install? Anyway, I got two with my KR2S project and am weighing the options (yes, pun intended). Now that we have the tailwheel thing done ; - ) Any opinions in regard to engines? Newbee KR project owner. L. D.

I did this for a trailer I had that came as a kit from China. I bought it from Harbor Freight real cheap and when I inquired about parts, like new wheel bearings, I couldn't even get an answer after three tries. I don't remember who I got the bearings from now or I would give you their address or phone. Good luck.
