L.E. you'll have an idea what angle of attack it's working at. Roll them up & tape them to the center section till you get to the "Test Area". Mike C.

Next step is to tape bits of yarn all over the tail, particularly the rudder, fin and fuselage to show the vertical flow. Taping to the stab and elevator for horizontal flow and possibly any stagnant areas on the bottom. Don't forget to have a few guys standing around in white lab coats with clip boards, horn rim glasses and those plastic pen thingies in their pockets. :-) :-) Clif Maybe some video of your tail (your AIRPLANE'S tail, that is...) would answer some questions... JM Hey Jim, great idea !! I have video pointing aft, from both sides of the cockpit, watching the smoke trail. Ya can't really see the position of the flippers very well, because of the angle of the camera, but it does appear to be slightly down, and I didn't note how much fuel was onboard when I did those flights. I will do several more flights, paying particular attention to the camera angle, and fuel onbd / C.G. location. One thing I've learned from all these flights with the video camera mounted, is that in normal bumps of turbulence, the camera exaggerates the movements. Quite often, it looks like I'm bouncing all over the place...on second thought, maybe I am, and I'm just used to it. It's very challenging to shoot good video while flying the plane trying to keep the subject in the viewfinder. I have to slip & skid circling a target, causing the ball to bounce back & fourth (the one on the panel). I have some really great video of three hot air balloons landing, and deflating. I circled them for about 15 minutes during their operation, with the camera pointing out the left side. I still have to do a flight with the camera pointing directly at the instrument panel. I'm splicing and editing all this video, to give the impression of many cameras mounted on the airframe. I'm really learning a lot, about what it takes to get good in flight video. It's looking pretty good, but I've been having problems with the video editing program (Pinnacle Studio 9). I've been in contact with them, and I have to un-install, and re-install it. That's a scary thought, because I don't want to loose any of the many hours of video I have on the computer. I still haven't got any of the video's to a finished point yet, but I do some stuff to them almost every day. They're all looking pretty good, though...if I can just get this editing program to do the stuff I tell it to do !! Chuck G.

Gotta smile at this. Long time ago as a student pilot planning a cross country into a strange airfield, I figured I'd take a pair of binoculars and scope out the field layout on the way in. Well, I found out that you (or at least I), cannot fly a plane while looking through binoculars. I was good practice for recovery from unusal attitudes. Maybe not that bad, but I quickly abandoned that idea. Looking back, that was a pretty stupid idea anyway cause inbound to an airfield is the LAST place you want to fly with tunnel vision! Joe PS - I was 17 or 18 at the time and full of stupid ideas. Now my ideas are still stupid, just more expensive. ________________________________ Message 3 _____________________________________ Time: 07:56:48 AM PST US From: Michael D Cuy Subject: Pietenpol-List: tail tufting awsonaviation> --> Pietenpol-List message posted by: Michael D Cuy Mike C. in KS---I've got a white lab coat if they need one to borrow and some pocket protectors from the geek engineer types here......

I see all familiar names and am happy you guys are going strong. I am selling my ribs and rib jig on eBay. I see Mike already posted the link. Thanks Mike. Last January, 2004 my wife was diagnosed with Ovarian Cancer and our family life took a tailspin. Eventually she pulled through with a magnificent Doctor, great attitude, and all of us pulling and praying for her. We are fine now but during this past year and a half I lost my desire to build, and found myself spending more time messing around with my other passion, motorcycles. It seemed more satisfying to work on a bike than my plane, I can't figure that out but I'm running with it. I'm selling the woodworking stuff and also my Piet blueprints. I'll have the prints on eBay later this week. Good luck to you all, keep building, keep flying. Kent Hallsten ________________________________ Message 10 ____________________________________ Time: 09:40:49 PM PST US From: Steve Ruse Subject: Pietenpol-List: Cruise speed... --> Pietenpol-List message posted by: Steve Ruse The more reading I do, the more I see GN-1s and Pietenpols with claimed cruise speeds of 70, 80, & 90+ MPH. My GN-1 with an A-75 cruises at about 65mph at 2,200 RPM. Going to 2,400 or so will net me maybe an additional 5mph. Nowhere near the 80+ MPH I see some people claiming. Now I understand I'm in a Pietenpol, and getting somewhere fast is not a concern, but I'm wondering if other people's numbers are real, or if the prop (or some other factor) is making my plane slow. The prop on my plane is a fancy Prince "Q-tip" composite/wood prop, I don't know the exact numbers, but I am trying to get them from Prince. The previous owner told me this is a climb prop, and the plane came with an extra prop that he said was more of a cruise prop, and would give maybe 70mph. Is the prop I'm using possibly slowing me down? The plane is right at 600lbs, I'm only ~170lbs, and the airfoil is the original Pietenpol airfoil. I see some people claiming 80-85mph in GN-1s with A-65s. The higher cruise RPM of my A-75 should give me an advantage over them. What am I missing? Should I really expect to get 80+mph in cruise? Thanks!
