41CC has a fixed (bendable) metal trim tab on the rudder=2C which sounds like a pretty common thing. See pic athttp://www.flysquirrel.net/piets/repairs/PC240001.JPGI cannot fly 41CC with feet flat on the floor in any operating regime but it also does not seem to require constant rudder bar pressure to keep the ball centered in cruise flight=2C so I guess the trim tab works fine. The rudder just needs the normal pressure to keep the nose straight and the ball caged on full-power roll and climb=2C which I do not even think about but just do automatically.I'm not sure how Corky and Edwin computed the required size and deflection for the rudder trim tab on 41CC but it may have something to do with the square of the mean rotational force produced by the outer 1/3 of the propeller slipstream divided by the logarithmic average of the left and right tire pressures (at sea level and standard temp./press.=2C of course)=2C corrected for the pilot's IQ and marital status.Oscar ZunigaAir Camper NX41CCSan Antonio=2C TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Subject: Pietenpol-List: Piet Ride?

Larry, IF you make it to Brodhead, and IF I fly my Pietenpol there, I'll behappy to give you a ride. You sound like the right size passenger. Ofcourse, I prefer passengers that are female, 5'7", 125 lbs, and 18 to 20years old. The prettier the better.You're a freight dog, aren't you? Do you ever fly into RDU? How about ROA?My Piet is now based at Smith Mountain Lake, VA (W91) but I could easily flyit to Roanoke (ROA) or Lynchburg (LYH) if you fly into either of those.Jack PhillipsNX899JPRaleigh, NC-----Original Message-----

Re: Pietenpol-List: Walt-- rudder offset

Dan, Things that come to mind are.......Engine mount not made to print. This can be corrected by adding large flat "fender" type washers between where the rubber mount meets the mount steel "flange".But if you need alot , you may have to slightly modify the cown in front, where the prop shaft comes thru. I remember the engine has to point down slightly, but forget if there's a side offset. If you're buying this plane, and don't have prints, I can get the mount infro to youUneven "angle of attack" of both wings, including equal Wash-in and Wash-out. Fairly easy to find. Put the plane on some Sawhorses, like you were going to initially rig it. Perfectly level the fuse side to side. Shim the back horse so that the rear center wing struts and front struts are level front to back. This means the fuse will be angled down (as per print).With the wing root and center section now level in both directions. (use the bottom of the wing, its easier)Go to the wing tips, and see what you have. should be slightly down for wash-in/out, But they must be EQUAL. If not, that's a problem. If made to the original strut type the end bracket which goes inside the strut end and is bolted to the wing brackets, would probably have to remade or the holes on the flat part would have to be filled with weld and redrilled.Not the end of the world. If so, the cables, if done to plans, would probably have plenty of adjustment left in the turnbuckles.This is probably the problem.If it's flown, any of the two problems would be confirmed by looking at the ball slip tube, if it has one. To correct , and fly straight with the rudder, it would show up thereMy Mentor always preached the importance of rigging a plane perfectly before building struts and covering.I've seen planes that looked great, but didn't fly right. Worst I've seen (not a Piet) you could stand 50 in front of it and see the wings were not at the same angle. Guess the builder didn't think it was that important.When I fly hands off, I can peek my fingertips from behind the windsheild and make a gentle left or right turn. One side of the plane has to the exact mirror image of the otherwalt evansNX140DL----- Original Message -----

Mike C.I know that if my mind wanders on climbout,,(hope it doesn't remember to find it's way home) and look at the tree tops etc, and look down and find I have not enough right rudder in, when I kick it in I can hear the engine "note" change and I climb faster.PS everyone try getting your Piet "in step" .......flying along, don't touch the throttle, push the nose down slightly, feel the increase of speed, wind noise, airspeed. You think you're descending, but you're not. Changes the angle of attack of the wing, Pulls that vacuum "bump" tighter to the top of the wing. You'll see 5 to 10 mph increase in speed, and you don't lose altitude.Check it out. Trouble is, I have to actively think of it. If I start looking at things, I revert back to the low and slow thing. Which is a good thing.Ain't Life Grandwalt evansNX140DL ----- Original Message -----

Thanks Steve, Jack for the replies..I freight-dog it thru Dover mostly as of late, before heading over the pond w/quicklayover usually, but thanks for your generosity Jack. And Steve, thanks aswell. I'm kind of looking for something more local (w/in 2hrs drive) than Oklahoma,but I'm definately planning to slip into Brodhead this year, if I my schedpermits. Mybe I can requisition a joy ride there
p.s. I'm liking the Yellow Piet as well as Jacks. Thought I saw it on youtube before.My goal when I build mine is a 3-piec wing, 3/4 inch, unroutered simple spar,Conti-powered like both of yours, x-c ability (extra fuel), antique charm/gauges.I'm liking both the wooden and the cub style to the gear.

Mine has 2" thick temperfoam cushions with leather upholstery. I flew it 13hours straight to get to Brodhead last year (with 4 stops for fuel). Iwould say the main XC limitation is its innate lack of speed.Jack PhillipsNX899JPRaleigh, NC _____
