Angle the fin to the left side of the fuselage (facing forward) for standard rotating engines and towards the right side (facing forward) for Corvairs-n'-such. Or just leave it like original and like most probably do and just hold a bit more rudder. Douwe Big day here, just shot the final color coat on the cowling and I think the spray gods were with me, looks pretty good. Start covering fuselage and tailfeathers next week!! ________________________________ Message 3 _____________________________________ Time: 07:00:18 AM PST US From: "Douwe Blumberg" Subject: Pietenpol-List: Binginlis books So Mike, It sounds like you are you suggesting that all builders get the Bingilis books? Douwe Do not archive ________________________________ Message 4 _____________________________________ Time: 07:47:45 AM PST US From: shad bell Subject: Pietenpol-List: fin offset vs eng mount offset In my experience building RC models, and the piet, It is usually better to put the offset in the engine mount, and not the fin.- The right thrust in an eng mount will not effect the power off/ low power flight characteristi cs like an offset fin.- It is also less noticeable cosmeticaly in my oppi nion.- The Bipe I am building has about an inch of offset in the fin, and if I didnt't already have the tailpost and fin spar drilled I would offset the mount.- We did need to add a rudder trim tab to the piet to get some left trim and I will shoot a picture behind me next time I go flying to se e just how much left rudder (corvair) it takes to fly ball centered in crui se. - Shad Do not archive....(Indiana Jones would find it any way) ________________________________ Message 5 _____________________________________ Time: 09:45:53 AM PST US From: Oscar Zuniga Subject: Pietenpol-List: Hegy prop; engine offset washers Sorry for the delay=2C but whoever asked about the Hegy prop=2C I sold it s ome time ago. Regretted it later =3Bo) Regarding washers=2C engine offset=2C and fin offset: Scout has about 1/2" offset on the leading edge of the vertical stab and that's all I felt comfo rtable cranking in because it looked like it would stress the glue joints i n the wood. It could use some more offset. The trailing edge remains fixe d while the leading edge is pulled over=2C and I didn't want to go with any more. It turned out well because I needed to offset the fin enough to wher e I had new material to screw the mounting tabs into anyway. If you build it with offset from the start=2C that would be best. Scout still needs a s mall bendable trim tab on the rudder as well as some washers on the engine mount to improve the yaw in cruise. It flies just about like the others sa y theirs do (mine has an A75)- about a half a ball out. Almost=2C but not quite=2C feet flat on the floor in cruise=2C but a good pilot's feet are ne ver on the floor anyway. By the way=2C I do not recommend the use of standard large AN flat washers for the engine offset duty. They are too thin and become dished. I ordere d a pack of nice thick black oxide-finished steel washers from McMaster-Car r and they are perfect. I believe they are the 92140A series washers=2C ab out a buck apiece in that size. I think Aircraft Spruce offers engine moun t washers but they are more expensive than the McMaster-Carr items. I boug ht a bag of 10.

Its nice to hear opinions or what is known as common knowledge of what to do or not do.
