This year I would like to begine testing different wingtips on my plane (they are removable) to see what works but I need some basic design info on different models. If I build a couple different tips I can change them out on the same day and get better test results - same plane - same day - for real life comparissons. Thoughts?

I've got a pair of these, and they came direct from Rand Robinson. I would think they are custom made for this application on a lathe, but I could be wrong. Mine are aluminum, and yours probably are too, but you might not realize it unless you unscrew the ends and see how light they are...

I'd get some 3/8" x .035" 4130 tubing and AN490HT6P rod ends and weld (or you can rivet, but welding would be better) the ends to the tubing the exact length you want. The only down side is that you might have a hard time finding a left hand thread on these, so you might end up having a more difficult time adusting them, and you'd have to buy two more right hand thread rod ends, but that would get you there. That's how I made all my pushrods...

I used a (Radio Shack) rotary potentiometer for the control (less than $5). I made a larger wheel for the pot out of plywood, painted it black, turned it sideways and put it in the instrument dash (lower left side in front of pilot). I just recently put a white tick mark on the wheel at the center position for trim. I do have pictures on my web site www.robert7721.com under instrument panel.

Those who care about isotopic trivia can read on. Speaking in my capacity as a Nuclear Engineer, the person who made the erroneous claim that lead is depleted uranium is really confused. Depleted uranium is the material left over when natural Uranium is refined into either nuclear fuel or weapons grade Uranium. Natural uranium is made up of two different isotopes. An isotope is a element with the same number of protons but a different number of neutrons. Natural Uranium is made up of approximately 99.3 percent U-238 and 0.7 percent U-235. Nuclear reactors generally use Uranium that is enriched to approximately 4 percent U-235. Weapons grade Uranium (the stuff that can make a really loud boom) is approximately 95-99 percent U-235. The left-over material from the enrichment process is called depleted Uranium and it is almost exclusively U-238. It has excellent mechanical and refractory (high temperature) properties and it is extremely dense. Uranium is naturally radioactive and undergoes decay to different daughter elements and their isotopes. I will not go through the full decay scheme, but the end result of the decay chain is lead, which is stable. Lead is not depleted Uranium but it does come from Uranium decay.

McDonnell was using depleted uranium as counterweights for DC-10 flight control surfaces as it was supposed to be heavier than lead and therefore took up less "real estate" in the wing. Several vendor supplied counterweights had the corrosion protective coating (some kind of heavy paint) flaking off the depleted uranium. They were immediately quarantined in the Material Review Crib for return to the vendor for reprocessing. Even the through holes for bolting to the control surface brackets were coated. No one was to touch the bare depleted uranium in any manner to avoid contamination to the individual. ------------------------------ Message: 23 Date: Sat, 16 Oct 2004 20:43:48 -0500 From: "Mark Langford" Subject: KR> canopy height, panel height, cockpit width To: "KRnet" Message-ID: <1bca01c4b3ea$bf71c540$1202a8c0@basement> Content-Type: text/plain; charset="iso-8859-1" NetHeads, I've flown in probably 10 or 12 different KRs over the years, and would like to point out a few things to those of you who are building, in hopes that it's not too late to keep you from making the same mistakes that many builders make. 1) Widen the fuselage at the cockpit, period! The simple truth is that anybody who carries a passenger in a KR2 or KR2S (they are both the SAME width if built per plans) will want to surgically remove the passenger's left arm at the shoulder to avoid discomfort. I'm pretty skinny, and I always have to put my arm around the pilot's neck to fly a KR. Don't let this happen to you. Widen it at least 3" at the shoulders, or kick yourself later when you come to the realization that your passengers will be miserable. It's easy to do (unless you plan on using the full RR premolds) and won't cost you much speed. 2) Make the canopy tall enough for passengers. You say you're short and you can see just fine? Your next passenger may need a lobotomy to fit inside. My canopy is 17" above the longerons (which is per plans, best I could tell), and my seat is 1" off the floor, and I only have an inch above my headset. It was worse than that, but I just spent the day hacking up my seat to lower it two inches! I thought I'd be OK until I bought the new Lightspeed headset that has an extra inch of padding on top. Your choice of canopy has an effect too. The Dragonfly is flatter across the top, giving ample headroom for both pilot and passenger, and allows more lateral space so you can look down over the side of the fuselage. But whatever canopy you use, it can probably be reshaped to some extent at the aft end to take on more of a squarish shape that'll be comfortable to fly in. I once flew in a KR2S that I had to bend my head over toward the center of the cockpit, and didn't even have enough room for my arms to move far enough to bring my camera up to my eye. 3) Don't make the instrument panel hang down more than an inch or two below the top of the longerons. Mine hangs down 1.5" below the top of the longeron, and I have plenty of legroom, but my legs are skinny. Some of these guys look like they're slipping their legs through slots. I got in one KR2S where my knees were jammed into the bottom of the panel, right at the knee cap. I'm still recovering. If you're using the AS5048 airfoil (the tall one), don't forget that your main spar just grew about 2" taller, and you're going to need even more room under your panel. Most of the panels I see have plenty of room to spare between instruments, and could have easily been "tightened up" vertically. If you've got two rows of 3.12" instruments, you've got enough. While I am 6 feet tall, I only weigh 142 pounds (that's why I get all the KR rides), so I'm not exactly a giant. Having said all of this, my wife would probably point out that I'm one of the few people on the planet who could manage to complain about having flown in so many different KRs. But I like to think of it as the voice of experience, trying to persuade you guys not to make the same mistakes others have made...

There is a data sheet on the System Three web site. It is only 24K so I can email it to anyone that can't find it. One other tidbit about T-88 is if you have a local Woodcraft store they carry it in stock. My store only has the small bottles, but when you run out on a Saturday you take what you can get.

I could get the part for you if they offfer it. What you are refering to may be a custom fabrication. I take it that it is a rod end bearing with two 1/4" studs, one on each side? I'll see what I can do.
