I think the design, cable and pulleys, is sufficient. Inspection holes, preflight walk around, rigid preflight checks rules, are the best assurance of a safe flight. Perhaps if the pilot involved did all the recomended preflight proceedures this would have never happend. lets all follow basic preflight proceedures, Gene % dave@erienet.net ------------------------------ Date: Thu, 8 May 1997 21:30:38 -0500 From: "Mark Langford" Subject: Re: RE: Re: KR: adjustable horizontal stabilizer > > Bill Ginn comments >> The expressions for static, > > stick-fixed stability boils down to the > > (stabilizer angle of attack) = (effective angle of attack) - (downwash angle) > > +(stabilizer setting angle).

I've been very meticulous in my construction (witness 900 hrs and I'm 30% done) in an effort to ensure that I know exactly what incidence, airfoils, etc. are on my plane. After I'm flying and I've dialed in my horizontal stabilizer, I'll be able to do a little reverse engineering and lump all of the variables together (call it "Buckingham Pie" theorem, if you like) and quantify them for future improvements that all builders can enjoy. I'll be the first to admit that formulas are great, but you know the saying: fly it and see...

Don, I think I'm pretty close already, having set the horizontal stab incidence at -1 degree from horizontal. The airfoil is set to +1 degree with reference to horizontal, oddly enough. I have .8 degree up and .8 down of easy movement available, which I think will be sufficient for my plane. If I have to move it, I'll probably just epoxy/flox the gap when the final incidence is set, since the shim for my 2.25" deep h.s. spar would only be ..031" thick at max travel. T-88 is reputed to fill that nicely, especially in compression. As for bolts, four through the aft spar (two due to the hinge) and four through the forward one, mainly because it also doubles as the vertical spar mount for the forward vertical stab spar and elevator bellcrank bracket. If any slotting is required, it will be minor and will be done to the spar. Now that it's all put together, I'll try to get a picture of it out soon.

I like this > idea a whole lot better than slotting the spar dude! Mike, I just sanded the longerons slightly to get the angles to sit right. I think what we were originally talking about was the geometry change that is required to adjust the h.s. after the angles are glued and bolted in place. Actually, the aluminum does bend a little, and the full support offered by the epoxy/flox connection to the aluminum negates any little hole in the middle of the spar. Removing a 3/32 shim under the forward spar allows it to travel down .78 degrees. A 3/32" slotting of the round hole doesn't bother me much, especially since my spar is 2.25" deep, and the stocker is about 1.875. And besides, the horizontal stab is usually pushing down on the longerons, rather than pulling up, so the load should be going thru the shims, instead of the bolts..

I did build my own gear that is a similar design. I used unidirectional glass tape, 3" wide by 0.025" thick, layed up in a mold that was 6 inches wide. It is mounted with a 0.125" thick 4130 bracket that is similar in style to the Diehl.

Bring it up to temp. with moderate oil pressure until the tappets and cam lobes wear into each other. Not sure how they expect you to do this on an aircraft engine (take the cowling & prop off? Chain down the plane?)

I used a Mikita with 80 grit carbide/resin belt sandpaper that I cut for the pad sander. Just a quick swipe with the 80 grit and then change to 100 grit. Be very careful because you can go through the fiberglass very easily. My whole plane was done this way. Had to do a few patches and went through the fiberglass because my arm got lazy. My feeling to do it any other way is pure torture. As for your engine, your right get that RPM up on startup and keep your eye on you temps and for any bad leaks, you probably will have a few, 20 mins is right, let it cool after this first run then try your different RPM and don't be afraid of to try full throttle. Don't baby it because your rings and all the other parts won't seat. Hope you used cam grease on your lobes and lifters. Good luck!!

Some back pressure on the exaust is recomended if no muffler exist, it keeps the valves clean and the seats sealed.

What would be the point of building your own gear? Lower cost? Somehow better than R&R, or Diehl?? Remember that about 2000 h of labor (not to meention $) will be riding on that gear... Unless there is some substantial gain in building your own ($ or other), I would stick to standard stuff... My 2 cents worth (CDN$, of course) OK, fine, I'll get back to my cage now :o) Cheers Carlos - ---------- To add to this, have any of you considered building your own glass "wanna be Diehl" gear? If so, and even it's only a concept, Details Please! I've got access to plans to glass gear, but don't know how it would apply to a KR.
