At one time, I had made notes as to how it worked, but I cannot find them now. I do not think it was as simple as making the distance between the holes the same as on the elevator horns and stick controls, but it might have been. I think it had something to do with the bellcrank hinge not being in line with the holes for the cables, so there is some other measurement that works that someone arrived at through trial and error to correct for this. I may be wrong whether it kept the cables from touching the stab, which does not bother me, really, but I know pretty much everyone raises the bellcrank to some amount to lessen the rub, at least. Adding pulleys at the at end of the pilot seat makes it possible to raise it as much as necessary. I think the only reason Bernie's rubbed was that he avoided the use of pulleys. Thanks for the help, keep it coming, especially the source for the spring.

Gene, I think that it is accepted that that's the way it will be, My cables rub, but when you add the piece of leather, they rub on that. And I don't think that you can perfectly correct the geometry on the cable taughtness. Believe me, Bernard knew what he was doing,,,I've been flying mine for 6 years,,and in no way do you feel a problem with the cables or controls. It's a blast to fly. Build to the plans.

I am reaching the point where I am starting assembly and need some specific information that I have seen on here before but cannot find now: 1. I have seen the dimensions to change the elevator bellcrank so that the cables (1 do not touch the leading edge of the stab) and (2 do not get tight/slack during movement through their range). The first requires raising the bellcrank, the second is a difference in the distance between the holes for the cables; 2. what is the source for the tailskid spring that most closely matches the one in the plans; Can someone help me with these??

Gene, I forgot to comment about the spring. My son had 2 old shock units off of a Honda motorcycle, 100 or 160cc. Kicking around. It was the exact size and compression to the plans.

Then to help with my arm getting tired when I forget to put the ballast in, I do a couple 12oz curls with longneck dumbbells after I am done flying for the day. Works good either way.

John Greenville, Wi ________________________________ Message 5 _____________________________________ Time: 08:49:50 AM PST US From: "Gene Rambo" Subject: Pietenpol-List: springs by reviewing the archive, I found the spring for the tail skid, a John Deere number is given that closely matches the one in the plans. I ordered it online, although it costs 18.00 now instead of 9.00 back then. I also found where we discussed (me included) Ken Perkins' fix for the bellcrank. I will try to contact him about this. It also looks like a couple of you may have bought his plans for the modified bellcrank, and I would love to hear from one of you.

Despite "iffy" weather in the morning, the clouds cleared, and a beautiful sunny afternoon arrived. The weather likely contributed to the slightly smaller than usual crowds. There were five Piets present. I've posted photos on Mykitplane.com: http://www.mykitplane.com/Planes/photoGalleryList2.cfm?AlbumID=328 Bill C.
