When I purchased mine it had flaps on it. It had been flying for years like that. I have not flown it that way, but I am going to leave them on. But I am rebuilding the entire airplane. So it will be awhile before we know how it handles with them on.Jerry GroganPrairie City, IAPieten 38 ----- Original Message -----

Uhhhh, rivets??? line of edge distance???The gussets are secured to the frame with adhesive. The nails (optional) are simplythere to hold the gusset in place while the adhesive cures.If you felt the need for bigger gussets than the plans show, one or two thicknesseswon't make any difference, but as far as I know, there have never been anyissues with the gussets on the plans being undersized. Actually, the gussetsize I drew in red is bigger than the plans show (see attached clip from the plans).It looks like the gusset plate in the photo is at least 20 thicknessesoversized (at each end).By the way, my comments about gusset size aren't specifically in reference to "Airplanestuff", but rather, to gussets in general. My schooling didn't includeANY "airplane stuff".When all else fails, refer to the plans.Bill C.Read this topic online here:

Flaperons... To bring stall speed from 35 down to 32. And with the added weight you'll have to increase your approach by 10mph so now you're landing at 42 mph.;-)I'm sure I'll get quote wrong but here goes: keep it simple and build in lightness.Dan-- yocum(at)gmail.comOn May 21, 2010, at 10:08 AM, Jeff wilson wrote:> Has anyone tried flaperons?

Actually, I believe the original quote was:"Simplicate, and add more lightness."And the saying is attributed to William Stout, who, among many other achievements,designed the Ford Trimotor.Bill C.Read this topic online here:

Add to that the fact that making the ailerons full span (when the flaperonsare operating in aileron mode) would add generously to the alreadyridiculously high amount of adverse yaw the ailerons produce, without addingsignificantly to the roll rate. I've gt a few hours in a Fairchild 22,which has both full span ailerons and the slowest roll rate of anything I'veever flown.But, go ahead. I mean these are EXPERIMENTAL airplanes. Some people evenput Corvair automobile engines on them, so why not flaperons?Jim Markle-----Original Message-----

Subject: Pietenpol-List: overbuilding a Pietenpol--some optionsGlider Mike, Welcome to the list. There are a great bunch of guys on this list, some of whomare real aeronautical, mechanical, and material engineers and those of us with fairly decent experiencesin building and been-there-done-that help for you. If you're one who likes to overbuild or redesign for more stoutness, don't builda Pietenpol. The design as-isis perfectly stout enough and has been flying as-built by plans for over 80 yearsnow without any of us makingit much better. Different maybe, better probably not. If you feel the need to overbuild then you'll want to do several things. Makethe wings a few feet longer say3 to 4 feet so you have more lifting area comparable to a Cub or Champ. The Pietwing is about 5 feet shorterthan your typical Cub or Champ. Use a larger motor say a 100 hp 0-200. Loose some weight if you're a full-figured girl like me. If you want a REALLY good flying Pietenpol build it like the plans say to buildit, no lighter, no heavier and you'llhave a good flying airplane. If you feel like you need to put in full instruments in the front seat, fully recliningvibra-seats with heat, airconditioning, carpeting, stereo, full electrics, avionics, vacuum systems, andautopilots with full night lighting then you're going tohave a single seat airplane that will be too heavy to carry a passenger and sharethe joy of open cockpit flying. As Jack said the Tony Bingelis books from EAA are an outstanding resource and Tonyshows you how to do it right, severalways to do it right, the pros and cons of each, the cost analysis of various buildoptions and will save you tonsof time in wondering "is this safe, is this right, is this going to be airworthy?"Use decent aircraft grade materials. Just because you could use Home Depot hardwareand cables please don't do it unlessyou just want to fly alone all the time. There are some very cool hardware optionspeople have come up with over theyears and you can search many of these topics on the Matronics web site thru thearchive search option. Sometimes as builders we can get stuck dancing on the head of a pin worrying aboutlittle things that aren't really worthworrying about since many aspects of building a plane this simple are just that--not complicated. Let common senseprevail. Don't add it if you don't have to or really don't need it. If youwant to make a cosmetic change, go for it. If you're going to redesign the wing spar or control system you're going not goingto be test flying a proven design unlessanother has already tried and flown that exact design for years with good resultsor you had some knowledgeable personanalyze it and bless it. Beware of old wives tales and hearsay. Beware of people who like to repeat informationand listen to themselves talk but havenever had any hands on building experience. Things like "I heard that after morea more than one-turn spin the airplane will........."but rather hearken to "my plan stalls at 30 mph indicated, power off" or "allof my T-88 glue joint test sticks broke in the wood, not in the glue joint." Best wishes--don't wait, order some wood, start building, spend more time buildingthan on the computer, and do at least some little project on the plane everyday or at least every other day if you can. Lastly--don't tell anyone you'rebuilding one so you don't get 50 visitors a month.
