Very interesting article Bill!Now, for the record, I was kidding about the RR engine in a piet. It would needquite a long motor mount :)I have a good friend that rebuilds those RR engines for the Reno Air Races, andhas worked pit crews there as well. Interesting to visit him at the airport shopand see 4-5 or those bad boys sitting around the shop and realize they wouldbe on the nose of the birds next summer. One of those bad boys weighs morethan an AUW piet doing a run up at the end of the runway!Anyway, it was fun to see the business end of those P-51's up close and personal.My friend told me he got to ride in a couple of the racers in the back seata couple of times and he thought about having the smile tattooed on his face!Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

The only radials that I know of were Lowell Franks and the way Lowell tells the story is, a guy offered him so much money for that engine that he unbolted it and put in the guys trunk before the guy had a chance to think about it.Then there was this Velie which is posed on another post.Also most of you all remember the fundraiser from a couple of years ago for the Jr. H.S. girls who were restoring a Pietenpol, it was built in the nineteen 1930's called the Compton Piet. That is hanging in the museum at Roundup, MT.Any way that Piet had a radial back when it was new.Then there is the west coast Piet which I have been hearing about but havent seen yet.There are several other Piets getting a Rotec around the world But I cant talk about themThen there is mine, if you look mine up up on the FAA web site I am listed having a Pietenpol Agineircamper with a P&W R-2800 engine I assure all of you I have a simple Rotec R-2800 with a 72x55 prop. Nothing more than that.Simple answer to the question is yes, Bernard Pietenpol was very aware of the radial engine but that isnt where his head was at he simply wanted to build a decent plane that the common man could fly with an automobile engine and parts from the hardware or farm equipment store.Dick N.----- Original Message -----

Hey Chuck,Seems most likely it would have been cotton and dope... so would imagine that whatevercovering system you're using and whatever you're going to paint with wouldwork. Don't know of any cloth wrapped wood gear Piets off the top of my head. Many folkswrap the ends of the struts with heavy twine or something, then just varnishit. Most old timey wood gear planes you see in museums either have some sortof metal cap for the ends of the gear legs, or twine or there I have seenthem covered. Alternatively, you could use fiberglass cloth and resin for the same effect (thoughprobably stronger).Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Re: My Days Work
