I don't have time to chase down every KR story to find out if it really is true, what caused the problem, and then figure out a fix. I'd be glad to buy a booklet with the necessary fixes in it.

I would guess most of us weight major assemblies like complete boat, elevator, spars, wing panels etc. I weighed all the wood I got but just to make sure that it was not too light. Most of my wood density came out to be around 29#/cu-ft which is the specified weight of aircraft spruce. Some pieces (engine braces) were as heavy as 35#/cu-ft and some were as light as 25#/cu-ft. The plywood always was very close to its specified weight. You can look in Aircraft Spruce or Wicks Catalog for that information. What I am trying to say is that if you need the weight of a particular part, you can just compute its volume estimate the weight. If you need weights of any specific parts e-mail me off net with a list and I'll fill up what information I have. I am at end of boat stage and my hangar mate, Mike, is almost done.

When I started, I went to the local (Orlando) FAA GADO office. I told them of my intent to build and showed them what I was building. They gave me package of forms to be completed. I went through the building process and had a EAA chapter designee (NOT an A&P) to sign my construction log about four times during the build. This is important when it comes time to buy insurance! When we both were convinced that everything was acceptable. and that all the paper work was complete, I called the EAA official Central Florida designee. He flew his own homebuilt from Melbourne, Fl. to Kissimmee airport, where I had already done low and high speed taxi tests, and did the final sign-off. The cost was $200. I took the paperwork,my photo album, my builders log back to the GADO office and was out of there in about 45 minutes. The FAA has never laid eyes on KR-2S N197DB! It has 90 hours on it now, and if I wanted to build another plane, it would be a KR. Happy Building and good luck.

I did and what a difference the rod end bearing hinges make. Talk about smooth movement, easily installed and self aligning. Best thing I could have done. Plus the overall looks put the stock hinges to shame. If you are interested in these hinges, the drawing for them can be found on Dr. Dean Collette's web site: www.execpc.com/~drdean/home.htm (thanks Dr. Dean for this hinge). Be sure to note the eyebolt lenghts vary depending on your horizontal and vertical spar construction.

This is mainly due to the pivot point on Rand's bracket does not align up with the centerline of the rod end bearings. However, they could be modified to work. The best bet is to fabricate new control horns using 6061-T6 aluminum 1" T bar. Your best bet would be to contact Dr. Dean of "Trailing Edge Technologies" at drdean@execpc.com and ask his advice.

Just more crap to be concerned about, if I were to do it again I would go will a fixed gear. One thing less to worry about on downwind. I have seen a few gear up landing on other a/c and it does not do any good to your prop. My KR only had a 4mph difference. With aerodynamic wheel pants you can exceed the 4mph.

FINALLY!!! Just to titilate your toasted taste buds, let me reveal a little of what will be found in this years video offering. You can expect to see KR's, lot's of them. The good, the bad and unusual. Some half done and others drilling the sky. If it was on the ramp, in the hangar, or flying, it's in the video. There's a couple of builder/pilot reviews (one is Tom Crawfords new KR shot at Sun'n Fun), a shot or two of the new airfoil Steve Eberhart built up, the Friday nite BBQ, lot's of flying KR's, and of course one rousing chorus of Jim Faughn's famous KR song. (I hate sanding) Now for the ground rules. 1. Do not respond to me or ask me questions thru KRNet. Anybody who does will not get answered. My personal email address is below. Use it. 2. The price is the same as always. $25. Cheap. Sorry, no Credit Cards this year. Only Checks, Money Orders or the green stuff. Tell me in your order you saw this post on KRNet and I'll see to it that Ross (#1 KRNet mom) gets $5 for bromine and other hot tub chemicals. That's in addition to the $10 you already sent him, right. 3. If you brought your KR to the Gathering last year, you qualify for a free video. I have most of the addresses of you guys, but just in case, drop me an email. Or better yet, tap me on the shoulder in a couple of weeks at the Gathering. Another way to qualify for a free video is to coordinate the KR Gathering or win one at the banquet. Your welcome Dana. 4. Review rule number one. Mail the fruit of your labor to: Bob Vermeulen 304 Cedar St. NE Grand Rapids, MI 49503 Video Bob mailto:bvermeul@concentric.net P.S.

It is not almost added weight and I believe that it is but sure, and mainly, but easy. To know that quantity weight goes in each one (having the total weight) we take the width of the aileron in each anchorage place (for example: 7´´, 6´´, 5´´, we added = 18, we divide the total weight x 18 and we multiply it for each step.

I don't know if there is such a thing as an engine that's too light but if you use one that is less than 150 pounds on a KR you will need to build your own motor mount so that you can mount the engine further forward. I don't know how much a Jabaru cost these days but I am willing to bet my entire project will cost less (including engine). -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Filling and Sanding again! http://www.fortunecity.com/marina/anchor/270/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: RE: Elevator/Rudder Hinges From: "J.R.L.

Go to www.jabiru.net.au Jabiru now has a 120 HP, 3 L, 6 cyl. engine which weights 161 lbs. twice the HP of a VW. I believe the reliability is equal to most aircraft engines out their. They are certified in Australia. Australia's certification is similar to the US. They are expensive however. They have the very latest technology of materials and machining. As far as balance they will include a engine mount made for the KR.

The original lock systems don't. I speak from experience. You don't want to spend six months and many $$ to repair your engine, cowling, antenna's and paint job because of a poorly designed lock system. I just finished repairing the above mentioned articles on my bird for that very reason. I had a total of about 150 hours on my KR-2 when the latches decided to pop up after landing and ruin my whole day. The prop alone was $600.00. I also rebuilt the engine with new crankshaft and heads, this was another approixiately $1000.00. Plus the time to do the rebuild and worst of all not having an airplane to fly during the process. The new system uses two 3/8 locking pins that slide into mating holes in two 1/2 inch aluminum arches mounted to the floor and the main spar at the hinge for the gear. I believe this system was designed by the folks that sold HAPI engines. I have the drawings if you want them let me know and I will scan them in and send them to you. Another thing you may not be aware of is the incorrect gear leg bolts . The original plans call for AN-3 bolts to hold the main gear legs onto the spring bar. These little 3/16 dia. bolts pulled right through the nuts on the second landing of my bird. This cost me six months work, a new prop and a lot of grey hairs. When I contacted Rand Robinson about it they said, " Oh yea, we have had several KR's do that, we recommend putting bigger bolts in the gear legs." I haven't given Rand Robinson the time of day since. You can also purchase your canopy from Aircraft Spruce for about half what R&R will charge you. I hope this information helps, let me know if I can provide further help. Regards, and happy building.

I also noticed they only have a 1000 TBO, gee seems like with all the new technology that is used throughout these engines they would have a higher TBO. So lets say a rebuild is gonna cost half of the original price. That's $19,425 for 2000hrs of engine service. Suddenly the Continental O-200 doesn't look so bad does it? As a matter of fact the VW is looking even better! Heck you could buy 5 new VW long blocks for the same price, forget rebuilding them! -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Filling and Sanding again! http://www.fortunecity.com/marina/anchor/270/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: Don't use the RR retract locking system From: Willard561@aol.com Date: Mon, 23 Aug 1999 22:21:07 EDT X-Message-Number: 21 Please send me a copy of the plans Bill Higdon Willard561@aol.com ---------------------------------------------------------------------- Subject: Re: 98 KR Gathering video From: jscott.pilot@juno.com Date: Mon, 23 Aug 1999 20:50:32 -0700 X-Message-Number: 22 On Mon, 23 Aug 1999 19:09:42 -0400 "Bob Vermeulen" writes: >Hey KR builders, >Since it's open line Friday and the commercial free barrier that surrounds >the hallowed screens of KRNetters around the world has been lowered, I will >proudly announce the release of ver.1.0 of the 1998 KR Gathering Video. >FINALLY!!! For anyone that hasn't seen any of video Bob's previous KR Gathering videos, they are worth the wait and more than worth the $$. Besides, your purchase will help keep KRNet funded as well. This last year we did a fair amount of Air to Air video, so I assume there will be lots of air shots of KRs as well as the usual fly-bys, landing shots, gathering memories and interviews with walk around tours of what is special about the airplane being displayed. Buy and enjoy.

I talked with the folks at 3M, and found that a piece of 3/4" big enough to cut two legs was about $1200. That's better then the figure you were quoted, but still way more then I wanted to spend. The aluminum stock for my legs ran me about $90.

You can see what I did at http://www.execpc.com/~drdean/hinges.htm also see http://www.execpc.com/~drdean/bell/alparts.htm to see how I made the aluminum parts. Although the part illustrated here is a bellcrank - the same principles apply. If I remember - I'll snap a picture or 2 of the control horn on my tail and paste it on that web page to give you a better idea of what the finished product should look like.
