Thanks for your interest Tom. They will either be aluminum or composite rotationally hinged plates that mesh into each other like the commercial ones that come up vertically,and fit flush when retracted. Probably cable and spring activated to save weight over making it otherwise operated. >Are you going to try them >at landing? Yes.Besides killing lift for a sharper descent, or using them for extra speed control if flying sloppy, I plan to use them to drop the thing onto the runway more easily during ground effect tantrums. :) But if that is the case, I might make them electric and have an on/off button mounted on the stick or somewhere close so as not to distract during the critical landing period. I think it would be cool to have something that pushes up vertically through the wing (other than the landing gear) in quick bursts, with fast retractions for custom controllablility. :) Solenoid time. Depends on how well they work or not. Might have to leave them on for a half hour just to get to pattern speed. The solenoids can also activate the guns on the wings, the sidewinders on the tips, and the flour bomb hardpoints on the bottom. ;) Robert Covington ------------------------------ Date: Fri, 06 Nov 1998 23:15:18 -0500 From: mike cochran Subject: Re: KR: Re: PIOs, a very old horse!

The ratio of completed airplanes to plans sold is probably the lowest in the industry and I think there are some very well founded reasons for this. As for myself, I spent a lot of time speculating on what to build. I had criteria I had to address in the selection that included cost of constuction, ease of building, initial outlay to get started and speed bang for the buck as well as builder support and number of completed airplanes flying. I really wanted a Lancair but the initial outlay would force me to borrow money for the kit and borrow money to build. I would need a lot of help building it. The financial picture was what took it out of consideration. After looking at a lot different possibilies, the KR2S came into the picture. It was the plane for me and is the plane for me. I am not a low time pilot but I'm not a high timer either but I have time in a lot of different "spam" cans. The are all different and they are all the same. It just takes a little while (dual instruction) to get "usedto" each one. I would have to think that a low time guy would actually have an advantage learning to fly a KR inasmuch as he would not have as yet developed any degree of complacency. The key here and probably the underlying reason for the low completion rate is the reputation of the KR as a "twitchy" aircraft that the plans buyer has not been exposed to until he gets into the KR "loop" as we are here on the mail. I know that it wasn't until after I made the decision to build the thing, and bought plans, that I was exposed to the reputation. I is my hope that the "S" version and our development of the new airfoil will tame the negative rep that the plane has picked up and that if all goes well in this arena, the KR2S will be sporty to fly by everyone and not a threat to anyone. By the way, this thing is a ball to build and this list is a ball to be on. Thanks, I needed that.

Mounting the cable to the U channel "horn" with a AN115 shackle through the nicopress thimble works well. The only problem you may encounter is the extra width of the U channel may not allow full up elevator as it may bind where the longerons meet at the tail. I moved my whole stab/elavator forward an inch or so to fix this. Make sure the last vertical uprights on the fuse sides match this final position. The full U channel sure looks more substantial than the single sided aluminum horn for a primary flight control. Regards Chris Gardiner KR2S 35% and climbing .

This question comes up all the time on KR NET . Regarding the distance from the elevator spar to the front of the rudder post; build the elevator/stab combo first and then position the whole assembly to suit , allowing for full elevator travel up/down. This is why " N" verticals are put in last to suit this positioning of the stab spar. Hope this helps. I have just finished this part and mounted the tail on the fuse so it is fresh in my mind.

Both Kevlar and carbon fiber will save you weight. But, each has certain characteristics that makes them useful or not. With Kevlar the overall weight savings will not be all that much when compared to the fiberglass due to the fabrics that are available. Few aircraft designers use kevlar on aircraft except in areas where damage resistance (puncture protection) is needed (ie., leading edge.) The fabric is about twice as "stiff" as glass. On the downside, Kevlar is expensive (about $1000 for a KR2S.)The real problem is that the stuff is a nightmare to work with (special scissors just to cut the stuff and they don't work all that great.) Carbon fiber on the other hand will save you more weight and add incredible stiffness. The stuff is a dream to work with (or so I have been told.) Many designers use this because of the stiffness to weight ratio - like Boeing, who is currently buying up all of the carbon fiber around and driving the price through the roof. That's the big problem with carbon - the price. Currently the stuff is about $29 a yard, and sometimes you'll have to wait to get the stuff. Budget $1500 - $2000 to do your whole project. Now my opinion - forget the Kevlar. So now we are talking about the carbon. When compared to total composite aircraft, the KRs don't use all that much cloth. Yeah, you'll save some weight, but in the end it's not all that much. But, if the stiffness is what you are looking for - go with it, especially in areas like the wing stubs. The wings might not be a bad idea as well (but expensive), if you make your own turtle deck (forward or aft) - you don't need the strength and the carbon is just costing you more (and not giving you anything.)

Anyone close to their first flight should be talking to current KR pilots and picking their brains for this kind of information. At the risk of being accused of standing on a soap box (again), here are a few things, briefly, to consider before you attempt to do your own testing. Am I current AND competent in type/similar type? Have I flown a KR or talked at length with an experienced KR pilot recently? Have I studied, memorized, and practiced my emergency procedures? Do I have a plan for what I am going to do during each taxi/flight? Am I confident in my ability to taxi/fly the airplane? (be objective here) If you answer "no" to any of these questions, you should do what is needed so that you can answer "yes", or find a competent test pilot to do the testing for you. By the way, these are "show stopper" questions -- just because you can answer these "yes" doesn't necessarily mean you are ready to go, but if you answer any of them "no" you are NOT ready to go. You don't need 1000 hours of flight time to do this, and you don't need to be a golden handed test pilot, but both you AND your airplane need to be properly prepared and qualified. AC 90-89A has a good outline of what qualifications you should have before you fly your homebuilt. I've also included my personal assessment of minimum qualifications in my test plan, which you can download from http://members.aol.com/eaglegator. If my airplane were finished today and I needed to start testing for some reason, I'd have to find someone else to do it because I don't meet all of my minimum quals right now -- be prepared to make this decision objectively, and don't waiver on the requirements you decided on. Set them and then meet them. Just remember that planning is important, details matter, and common sense must be liberally applied. Be smart and conservative, and you will minimize the risk of having major problems. Lots of folks have done it!

Each was 35 pounds. Allow maybe two pounds uncertainty. In lifting the tailwheel to reset the scales, I suspect that even less weight would be needed to keep ther tail down UNTIED. This was with a full header tank of gas Ron "Taxi Boy" Lee This brings up another question, could you tail dragging guys >(flying projects only) do me a favor and plop a scale under your >tailwheel in the parked position (tail down) and let me know what your >tailwheel weight is?

Any comments or concerns out there about which fluid is "best?" Thanks. Bob Maniss Abilene, TX>> Bob, aircraft brakes have to endure some really extreme temps and many have found out the hard way that they should have used "aviation hydraulic fluid". You should too, after all it is an airplane! Head down to your local airport and ask to buy a quart from someone. Its not that expensive. If you cant find it call Wicks or AS&S. - -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290 (Sky Pig 290) ,..Building ailerons and firewall now mailto:mikemims@pacbell.net http://www.geocities.com/CapeCanaveral/Hangar/4136/ Irvine Ca Fax 949.856.9417 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ------------------------------ Date: Sat, 07 Nov 1998 09:15:57 -0800 From: Ross Youngblood Subject: Re: KR: Elevator placement > This question comes up all the time on KR NET . > > Regarding the distance from the elevator spar to the front of the rudder > post; build the elevator/stab combo first and then position the whole > assembly to suit , allowing for full elevator travel up/down.
