I've discovered my tail post is 1" too tallit's 11 7/8". This "too tall" mistakecarries forward to the pilot seat back where the fuselage is 3/8" too tall (thestart 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 & balanceas well as handling characteristics; the rudder would have to be increasedan inch.Just something to ponder on a dreary day here.John--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: My measuring mistake

John,I am building a Piet with a steel tube fuselage, so my questions only come fromlooking at the plans, not actual experience building the wood fuselage. So takeit 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 tailpost is an inch too long? In other words, it extends 11 and 7/8' below the toplongeron? If so, can you not just make the vertical stabilizer 44 and 1/2", not43 and 1/2", as the plans show?Builders of the wood fuselage may throw a rock at me for suggesting it, but thatis just my initial thought.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Thanks Terry. The problem is at the lower longeron. When laying out the jig, Iapparently measured 10 7/8" from the outside of the top longeron and made my markfor the bottom longeron, but placed the inside (not outside) of the bottomlongeron 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 aninch. 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 gentlecurve from the tail to pilot seat back where the plane would be only 3/8" tootallJohn--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: My measuring mistake

Really, I doubt it would matter at all. Folks use all manners of tailwheels, somewhich change their own weight by that much as they wear.Aerodynamically, cannot it would matter either. This airplane lives in the middleof 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 amountof weight a thousand ways. The real issue is how YOU feel about it. Fixable with a lot of work, about twobucks of epoxy, and five bucks worth of wood. This plane was designed for 150 lb pilots, but 200 lb'ers are flying it. Nicespruce but dense doug fir is used. 1/16 wires but 3/32 is used... This isn'tthat big of a deal. I'm a fan of build to fix anyway, rather than strict plancompliance. FEW eyes are calibrated to one inch on this plane. Might matteron a Queen Anne period reproduction... But not this! In fact I'll bet things like cockpit wing cutouts, and scalloped trailing edgeschange the square inch amount of rudders and stabs more than this.MikeRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Spring Landing Gear designs

John;What's funny is that I have seen discussions about how if the airplane is built to the plans, the lower edge of the rudder protrudes below the tailpost just a little.
