KR> Undercarriage loadings
For those that fly around water. I put my KR into the lake here in Lake Dallas about 10 yrs ago. It floats real well. My wife told me to sell the plane, she did not want me to fly it again. 4 days later I had the engine running again and took the plane up. We kept a boat at the marina at the end of the runway. She saw me take off and got all p**t. I figured I better get rid of something so we got divorced. I loved my KR. --- bearlk...@aol.com wrote: > Mark's 5.5 g landing is a remarkable tribute to the > KR design and his > building skil.

KR> Undercarriage Loadings.
Net Heads Thanks guys for all your answers, it makes one think a bit more. Not only the undercarriange has to withstand the high loading but everything has to. Wings engine, things you hang on the instrument panel, the seat, as I say everything. The manual gives the flight loading + 4.4 g -1.7 g but Mark's 5.5 (& still in one piece) is getting up there a bit. Once again thanks to everyone. Robin. r.macdon...@clear.net.nz

Netheads, Those who have G meters has anyone any idea what is the G loading at a good bounce during landing ? Robin r.macdon...@clear.net.nz
KR> Undercarriage loadings
I've thumped a few at 3g's before in a Super Decathalon. If you are thinking of designing your own undercarraige FAR Part 23 has excellent information concerning this in regards to design and test criterion. You can find the FAR at www.faa.gov It would be good, in my opinion, to try to keep to FAR 23 as that's what the certified birds are minimally designed to. I don't recall off the top of my head what the limits are which is why I'm referring you.

The hardest I have seen on mine was 2.5 but I have heard others say they have had even harder landings.

I was quite surprised that no damage resulted, especially since I violated the Diehl instructions to "locate the gear brackets as close to the fuselage as possible". I thought to myself "well I'll never land hard, so surely he's not talking to me!". I did manage a 2g "drop in" the other day at Moontown, but quite often the g-meter never moves.

...and I can add the Diehl gear will bend to point where the wheel rubs on the wing having first ripped off the pitot tube without breaking or deforming either the legs or the brackets.

Mark's 5.5 g landing is a remarkable tribute to the KR design and his building skil. My flying partner bounced my AA1 (trigear, glass legs, 1500# gross) at 5.2 g's and we tore the engine down and replaced the prop for reasons that make me want to cry. The bent prop is hanging in my classroom. Note that the diehl gear are posted on his website as tested to 3 g's. Bob Polgreen

Robin The Cub didn't have a g-meter but I have bounced it higher than the hanger, a big hanger but Cubs are a lot tougher than most. I sure wouldn't want to do that in a KR.

KR>Undercarriage
Hi there I'm working on a Spitfire replica project that will include various construction characteristics of the KR series (basically similar airframe construction methods). My one big decision is how to do the undercarriage. Most of you will know that the Spitfire's main undercarriage retract out towards the wingtips and sweep back at an angle. This may be quite complicated to build for a homebuilt project, and my original idea was to include a similar set-up as used on the KR-1. My question is this: How thick is the wing centre section, and how far do the wheels (and the legs) project from the bottom of the wing? I read an article on Ken Rand's prototype, which states that the 8" diameter wheels only protrude about 1 1/4 inches, which would be ideal. Any more than, say, two inches would look really wrong!! Any help would be useful. Daren - Yahoo! Messenger - Communicate instantly..."Ping" your friends today! Download Messenger Now
KR>Undercarriage - KR1 to look like a Spitfire?
Daren, The gear moves only back, not out. There is quite a bit of it protruding from the wing and I don't think it is what you are looking for. Someone made a KR2 using motorcycle parts which could more likely be adapted to what you want. I am sure that someone on the net knows who that person and KR2 is. The plane was sold recently but I also never knew who bought it. See N64KR at http://KR-Builder.org - Then click on the pics Daniel R. Heath - Columbia, SC da...@kr-builder.org See you in Mt.
