    Subject: elevator cable routing under the rear seat
    Hello all, From my recent inquires, it's now obvious that I'm working on my controls. Today's question is: Do people still run the elevator cables thru the wood cross member under the rear seat, or should pulleys be located directly behind the rear seat to guide the cables from the control sticks up to the bell crank? If people still run the cables in that area without pulleys, are wear surfaces or some form of guides fabricated? Thank you for your help, John --------------------------------- See the all-new, redesigned Yahoo.com. Check it out.

    --> Pietenpol-List message posted by: Ben Charvet <bcharvet@bellsouth.net> I'm working on mine now too. I used a pulley to run the line to the top of the bellcrank, but the line to the bottom of the bellcrank is almost straight, so I'm running that cable through a piece of copper tubing. I put an oak doubler under the rear of the rear seat support to give some strength to the hole the copper tubing will mount in. I have a tubing flare tool that I willl use to bend a nice flange on both ends of the tubing after it is in place. I got this idea from Tony Bingelis's books. I'm not finished yet so take it for what its worth..... Ben

    --> Pietenpol-List message posted by: lshutks@webtv.net (Leon Stefan) I made hard wood guides. I got the idea from an old timer at Brodhead who said he did that many many years ago on an aircamper he still flies. The wood and cable show no ware, just a polishing from the cable movement He said. I drilled the ash at a roughly at the angle needed for the cables, then made the holes better with a Dremmel. I made an access cover under this area so I can watch it closely and put on pulleys if it comes to that. Leon S..

John, It seems that most folks use at least one pulley on the cable that goes up to the top of the bellcrank. However, there is absolutely NO reason that a pulley must be used there. I didn't use a pulley, and there is NO wear going on in that area, after well over 300 hrs operation. It simply rides on a piece of hardwood, however, I did tighten up one of the turnbuckles up a couple of years ago, and maybe after a few more years I may have to make another slight adjustment. Copper tubing is not a very good fairlead, because it has poor abrasion characteristics, and there is also what is called Dissimilar Metal Corrosion. Pulley's add complexity to the design, as well as the risk of a cable jumping out, and jamming the control cable. The beauty of the Pietenpol is in the simplicity of it's design. Changing even simple things like this adds an incredible amount of time, and thought that it takes you to build, and after all that extra effort, you still haven't made an improvement. Stick to the plans, and just Git 'er done !! Chuck G. NX770CG

    Hi Tim, I too, am tired of listening to the "old timers" whine about how the "good old days" are gone, and "what are we going to do?". I am 52 and have loved all-things aviation since I was 12. Good for you that you have completed your Private- Congratulations! You should be very proud of yourself. I always try to look forward instead of looking back. We all only have one life to live, and I for one do not want to waste one minute of it whining. I love every minute of working on my Piet and can't wait to fly her. After I get done I will be the one at Brodhead setting a new record for giving free rides to any and all who want them. If we all stopped complaining for a minute and actually counted all our good fortune, we would have to conclude that these ARE the "good old days". Dan Helsper Poplar Grove, IL.

    In a message dated 8/2/2006 1:26:47 PM Central Standard Time, Isablcorky@aol.com writes: Pieters, Here I am butting in on your conversations again. I am pleased to see some discussions begin on the subject of Piet technics. Granted, the Piet is a well designed machine and has weathered the years and hardly anyone has received harm. But can it be improved without changing it's basic designs? After completing and flying 41CC I felt that it's flying characterics could be greatly improved, especially the float after round out. Many said it was because of high drag that caused the falling brick sensation. The Cub and 7AC both have a nice float, are heavier and posses abundant drag AND with 65 HP. As I was building 311CC I strongly considered the Cub airfoil as well as the 7AC and the Clark Y. I feel now they are superior to the BHP French 10. If I were to build again it would definitely be with a different airfoil. That Piet airfoil is in my opinion the weakest link of the Piet chain design. Two-bits worth on this beautiful Southern afternoon. I'll be waiting your bombardments with my old steel helmet. CMC OK Corky, Put on that ol' steel helmet, 'cause I'm coming after ya !! he he !! If you change the airfoil of the Pietenpol, you Have changed it's basic design, because it is actually one of it's strongest links. Here's why: The airfoil is like flying with a notch of flaps, always in - high drag and lots of Lift. All this lift allows you to take off and land at very slow speeds, which explains why it has such a good safety record - injuries will more often if there is an increase if the touchdown speed has to be increased. This airfoil is also why Bernard was able to design an airplane with the power output of a Model A engine. If you float after roundout, you will certainly land longer than if you didn't float. Untill you really get used to the landing characteristics of the Piet airfoil, you should leave a little bit of power in, and land a little longer. It takes dozens of landings, but after you get used to it, pull power to idle on final approach, roundout and flair inches above the ground, and see just how short the roll out can be. Those other airfoils you mentioned are designed into those particular airframes, and are most certainly better than the Piet airfoil in that particular application. The Pietenpol Does NOT have balanced control surfaces, and if the top speed is increased with a lower drag airfoil, then you increase the risk of Control Surface Flutter. If flutter occurs, it will only take a matter of seconds before the subject control surface will have complete, and catastrophic failure. This is the reason you should NEVER take the Pietenpol past the design Vne of 90 mph. The Pietenpol airfoil has an aft C. of G. limit which is further aft on the airfoil than on almost any other airfoil, because of it's negative pitching moment, and if the airfoil is changed to something else, then you MUST use C.of G. limits according to the airfoil used - which will move the aft limit forward, and this will only aggravate the already aft C G condition that most Pietenpols have. There ya have it, Corky...my two-bit opinion :) Chuck G. NX770CG

    Subject: Re: Brodhead Pictures (Riblett)
    I understand him, once someone flys a Riblett airfoiled wing, will fall in love with it... Near here there is a pilot with an old Rans Coyote, his landing strip altitude is near 7,000 ft ASL and hot in summer. To make the story short, he needed to change the wing cloth (to many years flying), but the replacement was very expensive for him (including import and shipping), He was going to scrap it and quit... We convinced him to try to rebuild the wing using a Riblett (the one for ultralights) dacron and Latex... He now loves his plane, lower landing speeds, higher cruise with same gph, and can handle full gross with no climb problem... He is just happy and was a very inexpensive rebuilt. But the Piet HAS to be a Piet! (or a Grega), I think... Saludos Gary Gower Flying from Chapala, Mexico. Do not archive. Jeff Boatright <jboatri@emory.edu> wrote: Re: Pietenpol-List: Brodhead Pictures I think I overheard Lowell say that it's a Riblett airfoil and that Riblett had looked at the Piet airfoil, made comments on its strengths and weaknesses, and then postulated that this other airfoil would have all the strengths and none of the weaknesses. I had not heard that it was a NACA airfoil, though. Maybe I missed that part of the conversion. Probably the best bet would be to talk to Lowell directly. He is really sold on this airfoil and quite enthusiastic. Jeff At 10:32 AM -0500 8/2/06, Roman Bukolt wrote: Speaking of Lowell Frank's Radial Piet. He's very experienced at Piet flying. He has tried a number of engines on that plane along with a variety of wings including the original Piet airfoil. But the wing he has on his plane is not the Piet airfoil. It is an NACA4412. It's about 5/8" thicker and has about half the camberand a rounder leading edge. He says the climb is improved, cruise speed higher, better glide. I saw it take off. The climb was more akin to a Cessna 150. About double the angle of the rest of the Piets. That radial is a 90 hp engine and the the guy who flew it said he did not even use full throttle. Hmm.
