Not on its own wings, though, but in a crate aboard a MD11 Freighter of Lufthansa Cargo. It arrived safely , sits now in front of my garage in Linden near Giessen and waits to be assembled in the spare time I can find in the months( or years) to come.

Doug, sounds like intellectual property to me. :) I wasn't trying to be negative by characterizing it that way. If someone came calling asking me how I did specific things in my software business, in particular things that differentiate us within our industry, I would not be willing to share that. I would be giving away IP at that point. I was simply thinking that this particular modification didn't strike me as particularly valuable across the market of potential builders, and a great deal of the value is in the work itself, not the knowledge of how to do it. Perhaps I'm wrong. If so, it won't be a hallmark moment, it's happened before. It's certainly Ryan's choice as to what he shares Bill, you are more than kind. I will bug Ryan to respond to you, a couple pictures would be worth a thousand words in this case. I did not work on the two sets of tips that have been done so far. Your approach is completely different that what Ryan did. Might work better...who knows. But within a couple weeks Ryan has another set to do for his demo plane, you could also wait to see a few pix from that. You might contact him privately at _ryan@greenlandings.com_ (mailto:ryan@greenlandings.com) .

I think you are the first builder in Germany. I know you will enjoy the build process and certainly the flight performance of your airplane when you get it completed. Keep us updated on your progress and send some build photos for the newsletter as you make progress. Blue Skies, Buz Rich ________________________________ Message 5 _____________________________________ Time: 09:03:32 PM PST US Subject: Lightning-List: Re: Prop balancing From: "Bill Strahan" Finally got back out to the airport and worked on the plane. My initial numbers were WAY off. The Dyna-Vibe was getting errant reflections from the shiny spinner backplate and was reading 2-3 times the actual RPM. Of course, the vibration measurement, in inches per second was reporting a much lower number because it thought the prop was spinning much faster...anyway, long story short the actual vibration was just over 1 IPS! An even better testimony to the effectiveness of the mount, because that's shaking pretty good. I had it down to .05 IPS in 15 minutes and life was good. It's SMOOTH. If anyone is close to DFW and wants to come by and make use of the mounts I fabricated I'd be happy to accomodate them.

Metal What engine, solid or hydraulic. Hydraulic Hours on engine? 32 For what it's worth, it took about 15 grams of weight on the spinner backplate to balance it to .05 IPS.

There were many approaches, but the one that sounded the most interesting was the discussion wherein an individual with a Zenair (and I have it on good authority those are the brightest of guys!) related his solution of replacing it with a section from a radiator hose! I found a second person confirming this was their fix as well. So today I stopped into my friendly NAPA store and after some convincing that I REALLY did need to just go in the back and climb around to find the right radiator hose I came away with a lower radiator hose from an F-250 Diesel that had 90 degree bends on BOTH ends and appeared to meet the minimum 2.125 ID that I had come up with from a quick check on the plane. I got it back to the hangar, and set to work on it. Unfortunately, I cut it just a BIT too short, and was unhappy with it. It was close, but I wanted it to fit in place even without the hose clamp holding it to make sure there was no tension on it that would cause rapid deterioration. So I set to work on the other end, and trimmed it in small increments...and cut it too short as well! I then said "darn" or something quite similar. The tube exiting my airbox is pointed forwards slightly, and when I finally got it trimmed enough to fit, when it slid up onto the airbox tube it also slid back and away from the carburetor. Hmmm. Another trip to NAPA on the way home and now with two perfect examples of a 1/4" too short piece, tomorrow should result in a working part. I'll provide pictures and let you know what happens. The NAPA part number is 9415. I did have to stretch the end that goes over the airbox tube slightly, but it's just a nice snug fit on the carb. My plan is to get it in place, taxi out and make a few aborted takeoffs to get it nice and hot and verify that the RPM on application of full throttle is consistent. I can't imagine there is a big enough pressure drop to squeeze the hose in any way, since the drop across the air filter has to be tiny, but I'd rather see it in action a few times before I commit to a trip around the pattern. Should have news tomorrow or Sunday.
