From: "Jeff Boatright" Hello Good Pietenpeople! I an considering replacing the mid-70s skinny motorcycle tires in my Piet Air Camper with the big balloon tires that Bernard had on a couple of his, like the 1931 Air Camper 12236 with the 65hp Velie engine that can be seen here: http://www.pietenpolaircraftcompany.com/historic-pietenpol-photo-gallery I think they are also on the Allen Rudolf Air Camper. They look to be maybe 16 to 18 in diameter. Does anyone know anything about these wheels/tires? Thanks, Jeff Read this topic online here: http://forums.matronics.com/viewtopic.php?p=446294#446294 ________________________________ Message 3 _____________________________________ Time: 08:43:43 AM PST US From: "Gary Boothe" Subject: RE: Pietenpol-List: Re: Patricia's Pietenpol I believe that the comment made about spacing was done in good conscience. I would hope that anyone who sees a flaw, or thinks they see a flaw, in my Piet would have the decency to speak up. Interesting to note that the older version of 41.13 does not have the paragraph noting spacing on the empennage. My version is dated 1976, old yes, but, in this case, more restrictive. That's not a bad thing.

There's a picture of my setup that's taken at almost the same angle and distance, here- http://www.flysquirrel.net/piets/engine/a65004.jpg Hard to tell, but it looks like the oil tank is the same distance from the firewall on mine as it is on hers, and same thing for the distance from firewall to prop hub. The picture was when I had the A65 with tapered shaft hub on it, essentially the same setup as Patricia's airplane. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=446297#446297 ________________________________ Message 5 _____________________________________ Time: 12:08:48 PM PST US Subject: Re: Pietenpol-List: Re: Patricia's Pietenpol From: Scott Knowlton Not to step in to the middle of a thread but I visited the hangar that the a ircraft in question was being covered at. I was at the point of designing m y engine mount at the time so I diligently took a measurement of hers since I liked the proportions. 16" Scott Knowlton Sent from my iPhone > On Aug 23, 2015, at 2:22 PM, "taildrags" wrote: > > > I've looked at the photo showing the engine mount on Patricia's plane and a t first I thought it was definitely longer than the one on 41CC, but now I'm not so sure.

He says most people don't like them because they are taper shaft and most props won't fit. . IS there a parts or prop supply problem for Taper shafts? What is the difference? -- Blue Skies, Steve D ________________________________ Message 7 _____________________________________ Time: 09:23:48 PM PST US Subject: Pietenpol-List: Re: Patricia's Pietenpol From: "taildrags" Scott: Ah-! Now you're talking! I have all the W&B info and measurements that I took of my engine mount and everything else, and I'll check it out but I recall that it is pretty close to stock. For now, I can tell you by looking at the roll of plans right next to me that the Pietenpol family plans for the Continental mount (at the top) call for 11-3/16" from face of engine mount spool to the center of the bolt that attaches the engine mount to the mount fitting at the firewall, and 10-5/8" at the bottom, for a bit of downthrust. Less than 12" from rear of engine to firewall, I'd say, so Patricia's is a good bit extended from stock. This can help with tail-heavy. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=446320#446320 ________________________________ Message 8 _____________________________________ Time: 09:34:02 PM PST US Subject: Pietenpol-List: Re: A65 taper shaft From: "taildrags" Steve; I have had both a taper shaft hub (A65) and a flanged hub (A75) on NX41CC and have had props for both. On the taper shaft hub, there is a shaft that comes forward through the prop and that shaft secures to the prop by a flange that is bolted to the face of the prop. On the flanged shaft, the flange on the nose of the crank does not have an extension through the nose of the prop. It has drive lugs that engage counterbored holes in the aft face of the prop and the prop bolts pass through the crush plate and prop into the threaded drive lugs. I don't know what your buddy is concerned about, because people who have or want older airplanes with these engines are very aware of the differences between the hubs and how to fit props to them. I have never heard anyone mention anything like, "that's a taper shaft hub, I'm going to pass on it because I can't find a prop to fit it". The prop makers will bore and counter-bore your prop as needed to fit either one. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=446321#446321 ________________________________ Message 9 _____________________________________ Time: 09:59:13 PM PST US Subject: Pietenpol-List: Re: Balloon tires? From: "taildrags" Jeff; you might investigate the 'Dico' tires that a lot of the light planes like the AirBike have used and are using. I don't know who currently owns the design and markets them (maybe Titan), but they are balloonish tires with a 4 ply rating, a load range suitable to ours, and an "S-turn" tread pattern on them. Although they are not as tall as 16" or 18", they are sort of chubby and the price is quite reasonable. You can see them on my M-19 "Flying Squirrel", which is the airplane on the right, here: http://www.flysquirrel.net/hangar.jpg . The tires on my Air Camper (on the left in the picture) are 6.00x6 "Aero Trainer" tires, very good and very available at about $75 for just the tire, and you can see that the Dico turf tires are just a bit fatter and taller. For another possibility, you might look at the "Aero Classic" tires, which are meant to mimic the Stearman tire. Aircraft Spruce has the Aero Classic All-Weather and the Diamond tread, not cheap, although I think you are looking for the tires with just a straight groove tread. Nowadays the best cross-reference is going to be a turf tire like the golf carts use, or an all-purpose ATV tire. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=446322#446322 ________________________________ Message 10 ____________________________________ Time: 11:33:09 PM PST US From: "Boatright, Jeffrey" Subject: Re: Pietenpol-List: Re: Balloon tires?
