DO NOT BEND TUBING CONTROLS ! I'm going to go ahead and sneak out of my foxhole here and be the target by asking- why not bend the tubing? I know what the concern is: that the metal is taken past the yield point to deform it to the bend, however slight, and that now there is a weak point there which will induce buckling under a load. So how much bend are we talking about, and how much load? And how was the bend made? My feeling is that the control horn, or the stick, or something else would be bending as readily as the "bent" control tube if I cranked it over hard enough to buckle it. Obviously, a straight tube will transmit way more force than a bent tube without buckling, but how much force can be physically exerted on the controls anyway? With a slight and gentle offset made on a bender or mandrel -no kinks and no sharp or radical bends- why not? I think I'll try an experiment with some tubing one of these weekends to find out. Boy, I'm a caution, aren't I? It must be all these long nights working at the office. I need to get a life.

I know what the concern is: that the Hey Oscar, A bent piece of tubing will become a weak spring. Buckling is not the only problem, sloppiness in the controls is highly likely. A pilot with sloppy controls will want more control. A control failure is reportable to the NTSB. I would be absolutely flabergasted if an FAA or EAA inspector would accept such a state of affairs.

You know, when you ask for advise, you should be willing to take it. I would think that the overwhelming response to NOT bending tubes would be sending a message. The good thing about all this is that I am sure that someone out there has done that and is too embarrassed to talk about it. I hope they see this and take heed. Daniel R.

I have seen several designs that use a push-pull tube for rudder control. And often the run of tube from the rudder pedals (or rudder bar) is either bent or curved for clearance in the cockpit area. It will usually run thru a guide in the rear of the cockpit and terminate in a universal joint such as a ball rod end bearing. At that point it will join (at an angle no less...) another tube to the rudder. Of course you do not want a bend in a tube that is taking a torque load; but I see nothing wrong with gentle, well formed bends in push-pull. Just my .02 cents worth....

Message-Id: <20011206080049.SMRJ2789.femail35.sdc1.sfba.home.com@cx239334-a> In my earlier post, the spreadsheet did not get to KRnet. You can view the V-N diagram at: http://n541ry.com/FirstFlight.jpg This is a crude KR version of the V-N diagram in the Flight Testing Homebuilt Aircraft book. The top of the flight envelope is limited by N= 4g. The left side of the envelope is the stall speed under various 'G' loading. The right side is Vne. The formula for Vne is N = (V/Vstall)^2 Set N= 4 Then take the square root. 2 = V/Vstall... so using N=4 Va is 2X the stall speed. This sounds cool to me, but I am just beliving what I read in the book. I defer to other more knowledgable folk out there. As you can see from the graph... the first flight should stay away from the stall, and not get too close to Va or Vcruise. But this may be dependant on your situation. Vo (The max first flight speed) was not discussed too much in chapter 6. There was discussion of flutter testing, and that flutter is most likely above 140kts. I'm guessing this is a ball park number based on average flight surface areas and the forces these surfaces encounter. One could have flutter at even lower speeds I expect. In Vaughn's test plan, Flight #2 has six points within the envelope that are investigated which start at Vo pulling 2g's then go up to pulling N g's (in this case 4). Pulling 2g's is done with coordinated turns, but getting to 4 g's involves symmetrical pull ups. Kind of cool, and possibly easier said than done. Then he discusses the methodology to test for flutter by inducing a "pulse" into one of the control axis while trimmed at speed. Seems like a "G" meter would be really handy during flight testing to keep the "G's" within the flight test envelope as you expand it.

Rather, = the issue is that the tube will always try to rotate when under stress = so that the centre of the bend tries to lie below a line between the end = points.

If we had a manual, it could apply to any KR with an engine update. You could then modify it for any particulars that you knew. I have seen a lot of requests for KR details/specifications lately. I don't recall having to go through that with the Little Beast. With the KR, other that what is actually documented, and that can be changed, you are the final word as the builder. If you, the builder put it in the manual, it is what you say it is. Daniel R.

There is a Bendix service bulletin out that recommends overhaul every 4 years. Do not fly with that mag until you have it overhauled!!! Call Aero Mag at (760) 767-5711. They were recommended by Revmaster and have extensive experience with these mags. They have much more reasonable rates than other shops I called. Your mag will need replacement of some components to comply with AD's. My total for overhaul and labor was about $750. New mags cost over $2000. Please ask the people that know about this magneto. When they fail, both halves go and you are left flying a glider.

In a densely populated area. When he started having trouble, he called ATC and they vectored him to the Marlborough Airport. (9B1). The airport has a paved 1600 foot strip and not lighted. There was no way he could find the airport. He landed about a half mile from the airport. The only part of Rte 20, for about 3 miles, that was comparatively open. He stopped in front of a Shell gas station. Airplane was towed to airport. Untold story. Right tank was empty BUT gage showed half full. Left tank was full. Pilot was a 20 year old from a flight school. He and 3 of his buddies were on there way home after flying somewhere to get something to eat. At a time like that, do you think people believe in prayer ? Phil ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!
