You're absolutely right. You know all the 'stick time' that we accumulate during the building process ? Well in all the times I was sitting there moving the stick around on the ground I it never once crossed my mind that something should break......but on climb-out during my first flight I suddenly got this unwarranted sense of caution that those wing struts are holding the entire weight of me, my fuel, my engine, my fuselage, and my landing gear...and if they should fail now, I'm going down. After rationalizing to myself that I knew that I knew that every part of the plane was made to the best possible standards out of the best possible materials and inspected by several very knowledgeable people, that I was fine and should just enjoy the ride and the first flight. (and all the following flights:) The older guys at our airport are really good (like your Dick Lawson) and do everything the right way on maintenance and restorations, but the one guy will finish a job, show it to me, and say "it's good enough for who it's for." and of course he's joking--but its still funny.

I tell them that you can legally fly a plane like our from coast to coast without ever having to talk with anyone at anytime. My first two times to Oshkosh I went 100% non-radio in 1998 and 1999. Since then they have really tightened up the rules on NORDO approaches to Oshkosh, but it still can be done. Since then I bought myself a nice Icom handheld and really find between that and a puff or two of smoke in the pattern increases my safety and of those in the air around me.

Funny when you fly in a plane someone else built (including a factory) you don't think about welds failing and bolts falling out (at least I don't). You just assume that anyone that builds something as complex as an airplane must know what they are doing, that is unless I built it. I am sure that when I get this thing in the air some day and I hit some good turbulence I will immediately flash back to the welds on the flying struts and fittings, the T-88 holding the floor on the plane and keeping me from falling out the bottom, etc. Rick On 8/19/05, walt evans wrote: > > Anybody get to thinking ,,after you take people for a ride,, maybe during > the drive home,, "They asked the same old questions, "you really built this > by hand?

My glider has closed cell foan glued to both surfaces with contact cement. Dale ----- Original Message ----- From: Dick Navratil Subject: Pietenpol-List: gap seals I know that gap seals hve been discussed before, but I just want to ad a bit more to it. At Broadhead I had discussed my takeoff problems with a few of you. If I wasn't careful and didn't add power slowly, while pinning the stick foward, the plane would want to fly before it had the speed. This would cause the plane to want to stall at the ground. I thought this might be the way a Piet flew. After telling my story to the old timers sitting around after all had left, they told me not to look at moving the gear aft as I was thinking but to gap seal the elevators. I have piano hinge on the ailerions so I hadn't thought much about the elevators. After locating some duct tape at Brodhead I taped up the elevators. Right away it flew like a completely diffrent plane. It is much easier to handle on takeoff, tail comes right up and the stick is much lighter. On landing it is more responsive. In cruise it adds about 2 mph. My only question in all of this is, what to replace the duct tape with for a permanent addition? My first thought is a closed cell foam that we use at work as an expansion joint in concrete. Next might be strips of leather or a mylar tape. Any suggestions?

Subject: Re: Pietenpol-List: do you have to talk with air traffic controllers ?? --> Pietenpol-List message posted by: Jim Ash Years back some friends came to me after reading about a recent plane crash at a local grass strip in the Orlando Sentinel. The writer had volunteered a comment in the article that there was no control tower at the airport (no relevance to the accident, obviously). The article implied that airports without control towers were unsafe. My friends were shocked to read this 'news'. I asked them why they weren't shocked that there weren't traffic lights at every intersection of two roads, and how they managed to survive 4-way stop signs every day.

I promised myself I was going to read them before I started an airplane, and I'm glad I have so far. I I read, I've had some questions about options specific to the Piet. I've got the plans, including the supplementals and 3-piece wing drawings. I'm just trying to decide what makes sense for me. I'm 6'2" and 200lb, so I expect the long fuselage and the seat setback will be in order. I haven't put together a mockup, but it's coming. I was planning on building the 3-piece wing, but then I read that the typical three-piece wing adds significantly more weight to the plane. Now I'm wondering if this holds true specifically for the Piet. I've also seen comments that the Piet tube-and-fabric fuselage is significantly lighter than the wood one. I'm comfortable welding 4130 tubing, so I can go either way. I currently own a J-3, but if I take my wife for a ride, I'm about 70 lb over gross, so useful load in an airplane is one of my hot buttons. I'm not going to set myself up again for this problem, certainly not from the start, anyhow.

The strap takes the tensile loads and the ash takes the compressive loads. chris Braumeister und Inspektor der Flitzer und Flitzermotoren ----- Original Message ----- From: Douwe Blumberg To: pietenpolgroup Sent: Friday, August 19, 2005 6:54 AM Subject: Pietenpol-List: lift strut strap buckling Jeff, I too have seen this on many Piets, typically in the front strap. It must be hard landings where not only is the lift strut loading that strap in compression, but the gear bungee attachment is pulling that strut fitting down at the same time. I think this introduces a kind of downward "rolling" motion in that fitting which wants to buckle that belly strap. Most people just add more bolts. Interesting note, I've never seen it on a axle-geared Piet. Good luck Douwe ________________________________ Message 9 _____________________________________ Time: 07:36:03 PM PST US From: "Christian Bobka" Subject: Re: Pietenpol-List: RE: that is what greg and dale get from their 72 42 homebuilt prop copied from an old sensenich blade.

That's about what I get from my homebuilt 72 X 42 prop, with Cont. A65 engine. I added aerodynamic fairings to the gear legs, and jury struts, and now I have to hold some forward stick pressure. I plan on removing the fixed trim tabs on the flippers. The fairings helped clean up the parasite drag, a little bit. Chuck G.
