Subject: Pietenpol-List: props on corvair motorsI am curious as to the props used on Corvair engines on the Pietenpol. The composite props do not look right on the 70 + year old design. what length andpitch are most of you using and what Prop company manufactured it or did you make your own?Ted StoneI have quite aways to go before I need a prop.________________________________________________________________________________Date: Sun, 17 Sep 2006 14:34:38 -0700 (PDT)

Hi!I just received my prop yesterday which I purchased through William Wynne.At his request, I sent him a check for $700 in May. He, then, ordered the prop from Sensenich.It's a beautiful piece of woodwork with somewhat of a scimitar shape.Diameter is 64 " and the pitch is 52 ". ----- Original Message -----

Follow up on prop pitch:I called William Wynne today because when I had him order my prop for my Pietenpol, he recommended a 64 x 33 prop.So, today I called him to tell him they shipped me a prop with a 52 in. pitch.After he seemed to recover from a near fatal cardiac arrest, he mentioned someone was supposed to get a 54 x 52 prop for his small high performance plane. Now William is thinking Sensenich somehow screwed up and probably made this guy a 54 x 33 prop.William said he'd talk to Sensenich and get this all ironed out, then call me back. Haven't heard from him yet. Maybe he DID succumb to a cardiac arrest??Anyway a 64 x 52 prop is NOT a good idea for a Piet.Stay tuned for continued coverage of the Sensenich Saga. ----- Original Message -----

I'm confused, what does wind speed have to do with climb angle? I would much rather climb out shallow 5 mph over stall then steep at 20 mph over. If your flying along straight and level then cut your engine while trying to hold altitude you will reach critical angle of attack at about 18 deg. and stall. With only mother nature for power and no engine you will have to drop the nose below level maybe 10 deg. to start flying again that's 28 deg. total movement to start flying again. Now if your climbing out at a 45 deg. deck angle and lose your engine your relative wind goes away almost instantly which leaves you 45 deg. nose up with at least 10 below level to start flying. That's 55 deg. total movement to fly again. You will not have enough altitude to achieve this before messing up a good airplane and runway.Bryan Green (Elgin SC)----- Original Message -----

Bryan,It all a matter perception, for spectators on the ground a strong head windwill create the illusion of a steep climb angleFor the airplane and its pilot there is little difference if he maintains asafe airspeed.Ever "hovered" a Pietenpol in a strong head wind (30 - 40 Mph and goingnowhere)Please do not try at low altitudes!Be safeHans "bryan green" To Sent by: owner-pietenpol-l cc ist-server@matron ics.com Subject Re: Pietenpol-List: First flight.. 09/19/2006 06:10 AM Please respond to pietenpol-list@ma tronics.com I'm confused, what does wind speed have to do with climb angle?

Only an aerobatic pilot will set at zero to fly an airshow. Then set it to field elevation to fly home. ----- Original Message -----
