This "too tall" mistake carries forward to the pilot seat back where the fuselage is 3/8" too tall (the start of the error). I'm about to dig the nails from gussets before I start the job of gusset removal. I was wondering how much of an affect that extra inch would have on weight & balance as well as handling characteristics; the rudder would have to be increased an inch. Just something to ponder on a dreary day here.

So take it FWIW. Are your top longerons parallel with the ground, or is there a slight bow in them? If they are have a bow, then my guess is that you have a problem. However, if they are parallel to the ground, then are you saying that the tail post is an inch too long? In other words, it extends 11 and 7/8' below the top longeron? If so, can you not just make the vertical stabilizer 44 and 1/2", not 43 and 1/2", as the plans show? Builders of the wood fuselage may throw a rock at me for suggesting it, but that is just my initial thought. -------- Semper Fi, Terry Hand Athens, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465340#465340 ________________________________ Message 5 _____________________________________ Time: 12:44:24 PM PST US From: Ben Charvet Subject: Pietenpol-List: Spring Landing Gear designs Hi all, A long time since I posted anything. Yesterday morning on pre-flight I noticed that the lashings on one of my bungees was slipping. Its time to change the bungees anyway, and it seems like a good time to convert to spring struts. I have Hans VanderVorts design in hand, and I've also looked at William Wynn external tube design. Those of you already using these designs, are you happy with the spring that ACS sells, or did you use something from McMaster Carr that works as well? I've seen several Piets with the exposed spring design, but haven't seen one like the Wynn design, though it looks like it would be easier to convert using pieces from my existing gear. Your thoughts welcome!

The problem is at the lower longeron. When laying out the jig, I apparently measured 10 7/8" from the outside of the top longeron and made my mark for the bottom longeron, but placed the inside (not outside) of the bottom longeron there, giving me a tail post 1" too long. The top is straight. If I leave it as it is, I'll have to extend the rudder an inch. I'm not sure what else could be affected. I'm trying to stick to the plans, so this irritates me. I'm curious, though, how much that 1" would affect the aircraft. It's a gentle curve from the tail to pilot seat back where the plane would be only 3/8" too tall John -------- John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465344#465344 ________________________________ Message 8 _____________________________________ Time: 02:14:42 PM PST US Subject: Pietenpol-List: Re: My measuring mistake From: "jarheadpilot82" Gotcha.

Folks use all manners of tailwheels, some which change their own weight by that much as they wear. Aerodynamically, cannot it would matter either. This airplane lives in the middle of a wide range of good. About the only hinky thing is weight and balance, which should be checked anyway, and which is correctable for that minor amount of weight a thousand ways. The real issue is how YOU feel about it. Fixable with a lot of work, about two bucks of epoxy, and five bucks worth of wood. This plane was designed for 150 lb pilots, but 200 lb'ers are flying it. Nice spruce but dense doug fir is used. 1/16 wires but 3/32 is used... This isn't that big of a deal. I'm a fan of build to fix anyway, rather than strict plan compliance. FEW eyes are calibrated to one inch on this plane. Might matter on a Queen Anne period reproduction... But not this! In fact I'll bet things like cockpit wing cutouts, and scalloped trailing edges change the square inch amount of rudders and stabs more than this.

So, it may be that you're ahead of the game ;o) Here's an example, Chuck Gantzer's Piet: http://www.westcoastpiet.com/images/Chuck%20Gantzer/images/ride.jpg Here's another, Gary Boothe's: http://www.westcoastpiet.com/images/Gary%20Boothe/images/P1040823.JPG And another, Kevin Purtee's: http://www.westcoastpiet.com/images/Gary%20Boothe/images/P1040823.JPG And finally, you can see in this very close-up photo of Kurt Shipman's airplane that if you don't flatten or round-off that very last bit of the rudder, it will be just a bit longer than the bottom of the tailpost and won't fair into the line of the lower longeron. http://www.westcoastpiet.com/images/Kurt%20Shipman/images/P1010094.JPG -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465362#465362 ________________________________ Message 21 ____________________________________ Time: 07:48:52 PM PST US Subject: Pietenpol-List: Re: My measuring mistake From: "taildrags" ...whoops... here's Purtee's Fat Bottom Girl: http://www.westcoastpiet.com/images/Kevin%20Purtee/images/IMG_0114.jpg -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465363#465363 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
