Larry, you are correct and I back your observations where I am included in your post. You are correct that a 1350 KR will not rocket into the air but if the CG is ok, it will fly. Just expect longer take off roll and slow climb. Mark Jones (N886MJ) Wales, WI Visit my web site: http://mywebpage.netscape.com/n886mj Email: flyk...@wi.rr.com

I'll let these gentleman correct me where I'm in error. Jeff's KR is stretched, I'm not sure how much, and his empty CG is at or near the very forward limit to start. He is flying a recently rebuilt 0-200 with C-85 pistons and probably is getting a reliable 110 hp. As I recall, he is flying on the longer wings such as the Diehl skins. Other than, as he mentioned, the standard size cockpit being a bit crowded, his KR probably performs well with 410#'s in the cockpit. My KR is running a tired 0-200 (2000 hour) on slightly less then stock wings. I once rode in Marty's KR and it was CROWDED. I couldn't get my legs under his panel (I'm 6'4", 200lbs) and my head was touching his canopy. Marty was running an 0-200 at an rpm that was probably giving him 120hp at full throttle. I think he was turning 2800+ rpm and maybe pushing 3000. If you throw another 50 to 60 pounds passenger weight in either of the above mentioned KR, I suspect you will be pushing the edge of the envelope, either performance or CG wise, especially in Marty's KR on the CG. Also consider where your fuel weight is and which way the CG will move with fuel burn. You might recall Steve Glovers recent post regarding aft CG and controlability. We might throw in another KR that is pushing the envelope. Is it Keith Kottle running the Jabaru? As I recall, he stands about 6foot, 6 inches tall and has modified his KR to his size and weight. With all due respect, I'm still convinced you can't start with a 260 pound pilot, expect to add a passanger of any significant size and have a KR that performs the way we expect a KR to perform. That's not to say it won't fly and can't be set up to fly safely but you'll need plenty of HP and the some major considerations made in building to set it up correctly. My only caution is to keep a good grip on reality when planning/ building your KR. If it's a bit heavy, say 750 pounds, the pilot weighs 260 pounds, expects to invite a 200 pound friend along and add 25 gallons of fuel, don't expect a 1360 pound KR to go rocketing off into the sunset. Larry Flesner ++++++============+++++++++++=========++++++++========== Last year's Gathering when I took Rick Corkendahl (I probably slaughtered the spelling of his name) with me in my KR, we had a front seat weight of roughly 410#. I think Rick would probably attest to it flying significantly sharper than a Cesstruck, in climb and all other aspects of flight. >Jeff Scott ++++++++++++++++++++++++++++++++ And if you seen me and Marty in his KR-2 packed in like a couple of sardines, you would think his performance would have been compromised but it was not. On his high speed pass down the runway, the ASI was reading 219 mph. I would be willing to bet we had 420 lbs in that seat.
