I used snaps. Are you talking about those little things about the size of adime that they use on boat covers, etc.? Hardly notice them on mine.Ted Brousseau----- Original Message -----

Subject: Pietenpol-List: Re: Pietenpol-List angle of incidenceWhen one is figuring the angle of incidence does the thrust line of the piet airfoil go thru the center of the radius on the nose of the rib or along the flat bottom of the rib? Also what amount of incidence have you guys been using between the top logeron and the rib thrust line?

Most automotive upholstery shops can get you black snaps (instead of silver)& they may also have some other ideas on hiding them -- ask what the streetrod guys are doing!? You could also sew the fuzzy side of velcro to yourcockpit padding & sew the hook side to your cover (with a couple snaps inthe corners where they won't be seen -- the "belt & suspender" method.)Mike C.

Steve E.,Are snaps the way to go? funny how you look at all these planes at fly-ins,but when it's time to recall details, you draw a blank.Hopefully I can fly off my hours during the NJ winter, ( and I'm glad I putin cabin heat, but don't know if it really works)figured if I block off the front I'd be better off.walt----- Original Message -----

Subject: Re: Pietenpol-List: covering the front holeChuck....I would like to see some pics of your aluminum cover , Ithought that was my idea in fact...you beat me to it...How do you fastenit down?? Also ...has anyone tried useing a simple cabin heat systemwith a front cover on. All the heat would have to pass the pilot on theway out. When I was young and crazy I used to ride around in the snow (up north) in my convertible 442 with the top down and the heat on. itwasn't too bad. you could really feel the heat. If you would send mesome pics of the cover I'd appreciate it. Thanks Ed G. ________________________________________________________________________________

I have a couple of pictures of the typical snaps 'n' naugahyde cover as used on Ernie Moreno's Piet at http://www.flysquirrel.net/piets/piets.html and you'll see that it isn't all that bad looking. As mentioned, you can get snaps in black rather than shiny, and although Ernie's cover isn't particularly pretty, you can see that with a little work (such as sewing in some pockets on the backside so you can slide in some slim fiberglass rods to have the cover follow the curvature better), it can be made very acceptable. Somebody mentionedh a hinged metal cover and that is super-slick, but the naugahyde cover is easier (IMHO) and easily removable.Now ask yourself: "what would Bernie do?" ;o)Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.netSTOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junk ... __________

By definition, the line of reference is the thrust line of the enginealthough this has fallen out of favor because people like to change thethrust line. This opens up a can of worms.chris bobka-----Original Message-----

Charles Hampson Grant - Model Airplane Design and Theory of Free Flight -see pages 132-134 for discussion. This book is awesome and goes hand inhand with the pietenpol design. CHS is the patent holder of the taillessdelta, the variable cambered wing, the slotted flap, etc. He built anairplane and taught himself to fly as a teenager in 1909. Then he went toPrinceton (BS Civil Engineering)and MIT (graduate of the School of MilitaryAviation) and then worked at Wright Field as Aerodynamics Engineer from WWIto late twenties. He was a proponent of testing theories using modelaircraft that are identical except for minute changes that he could use togood advantage to obtain data about their effects to flight characteristics.Ultimately he taught the WWII generation of pilots their aerodynamics bybeing editor of Model Airplane News for about 25 years starting in the earlythirties.Chris Bobka-----Original Message-----
