A builder changed his fuel filter system after sign-off, then had an accident. I don't think he busted any FAR's per say, but they didn't cover him. Also, we know that DAR's criteria vary from location to location, so I think you might not have a problem down in Medford, OR. Also, lets suggest that as an "Experimental" airplane you have decided to put a Ford Tarus Airbag in the cockpit instead of any seatbelts whatsoever... does this violate regulations? Probably as I think there are multiple catagories of Experimental, but it's food for thought. The tough part would be keeping the airbag from going off in mild chop, or on a bounced landing. I guess you would need an SUV airbag instead of a Tarus. -- Ross 12/5/2001 3:16:35 AM, "Oscar Zuniga" wrote: >Netters; > >Here's a theoretical question.

In the inspection report it asks if the seatbelts are T.S.O standard or equivalent? So I am certain that aftermarket automotive racing type belts(4 points to attach) would cut it. If you are really going to use rope, I suggest 11mm climbing rope and if you need some let me know.

Please use an adjustable type or right length. You're scarin' the heck out of me talking about bending tubes. Definitely adjust your ratio so you can get full aileron in a reasonable range of stick movement. Use the length of the bell crank or stick fulcrum to adjust.

(Mike Meyer) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++= Mike, Have you measured your aileron deflection yet? You may not need to move the stick that far to get the deflection angles called for in the plans. I haven't flown a KR but with the light stick forces claimed by those that have, I'd think you could change the stick geometry a small amount to get the required deflecton with less travel. Keep in mind , this may change the pitch to roll sensitivity of the stick and give the controls a different feel. Just my humble, uneducated opinion. You should be able to figure out on paper the aileron bellcrank travel needed for the proper deflection. Draw it up full scale and measure it. Remember , the bellcrank moves in a circular motion about the aileron hinge point and not in a straight line so measure the circular motion distance. Do the same for the stick assembly and any bellcranks involved and you'll know the geometry needed. Larry Flesner P.S. also, how often will you be using "full" deflection? ------------------------------ Date: Wed, 05 Dec 2001 13:09:47 -0600 To: kr From: larry flesner Subject: Re: KR> Controls Message-Id: <3.0.6.32.20011205130947.007afd00@pop3.norton.antivirus> Mike, What I ment by "pitch to roll" sensitivity is that you don't want you stick to move considerably more for a roll input than for a pitch change or vise versa. Imagine trying to fly and aircraft that required 1 inch total stick movement in pitch and 4 inches for roll. I'm not sure I'd be able to get used to that. Try to keep it balanced.

I used a 5/8" diameter stick between my legs and have to really jam it over against my thigh to get full aileron deflection. I have been flying my KR for ten years now and have never had to use full deflection ever. So little stick movement is required in normal flight conditions. If I ever do need it I will just jam it over. I would be concerned about reducing stick deflection as this would make the ailerons more sensitive to a given deflection.

(Still have cable for rudder only.) Aileron bellcrank should move 3/4 inch from neutral to get full aileron deflection. Then stick movement should not be greater than 30 degrees from neutral. At least that's what I have for movement. I used 1/2 inch 4130 tubing for aileron push rod. This is on the KR-2 not KR-2S. Also, when I discussed the problem of converting to push pull system, everyone was very emphatic. DO NOT BEND TUBING CONTROLS !

Put 30 lbs. 5.00 X 5 tires and it was much better, the tires have to take some of the shock load as well as the gear. My gear is from Grove A/C just like the Cessna but straight across the bottom of the fuselage, tail dragger. Netters, I have found what causes the problem with high temps on climb out. I have a Revmaster 2100D with Revflo carb and gravity feed. I thought it was the ram, excess air going out through the filter into the lower cowl reducing cooling over the cylinders. To fix this I put in a shroud over the filter with a hose to the exhaust pipe shroud. A rubber flap opens when the ram tube is closed to get filtered hot air for carb heat. This increases the ram air pressure into the carb making it run leaner. I tried carb heat on takeoff the other day thinking carb ice was the problem, the temps came down but so did the rpm. It would still climb so I tried a bit of ram air and could get the rpm up and still keep the temps down. I am going to reduce the ram air opening with ducktape and make a hole half the ram tube diameter and go up from there until it runs correct. Have any of you had this problem?

That is to say there's np pressure regulation, rubber diaphragm or float bowl or anything. My lawnmower is a better equipped. As the input air pressure rises, mixture decreases. The Fuel tank pressure is probably dropping if the vent is in the area just ahead of the windshield, and the ram air pressure is rising. Since there is zero regulation, mixture changes. The answer; get a real carburetor. An interim answer might be to provide ram pressure to the fuel tank.

Make a al slide with a set screw or screws and be on the safe side. Carried 45 lbs in my lamb tires low pressure causes the split rim to work if your using this, hope you covered the facing halves with wide vinyl tape because sooner or later it will pinch the tube. Nothing like learning to land with a flat tire that you are unaware of. Cubs 6-8 lbs and the KingAir 90lbs. Happy Flying to all, also, to all a Very Merry Christmas!!!

I've seen 'dual throttles' as you're asking about on two homebuilts, it's actually a good idea. The arrangements I saw, both on CH-701's, had push-pull controls on each side of the panel. The control cables from the throttles ran forward and were contected to control arms attached to a tube that ran across the top of the firewall that was mounted in 'pivot bearings' (next size up tube). Mounted to the center of these tubes was another control arm from which the cable to the throttle ran. It's a pretty simple arrangement, one that adds lots of versatility with not alot of weight or complexity. Hope this helps. mailto:pjohnson@voyageur.ca ----- Original Message ----- From: "Bob Sauer" To: "kr" Sent: Wednesday, December 05, 2001 12:45 PM Subject: KR> Dual throttles Has anyone installed dual throttles, either military type or panel mounted push-pull (vernier)???

Since I have a center stick, this is the arrangement that I was planning on using. I am not going to have mixture and carb heat on the right side, just a second throttle for those few times when the right side person has control. I also have a small project update for those interested. I did a quick weight and balance today in preparation for beginning the engine mount. The total weight, basically completed from the firewall aft, is 461 pounds. My target weight with the larger size and all mods was 750 pounds and I think that I am going to come close. The engine and accessories, mount, prop, and cowling should come in at about 250 pounds. Final finishing, paint, and all the little stuff will add 20-50 more. For those of you that don't know, my project is significantly modified, lengthened, and enlarged. It looks like a KR on steroids, with a nominal gross weight of 1400 pounds.
