Pietenpol-List: Fuselage - Long vs Standard

I haven't had the chance to check the list in a while, but it's a little ironicthe flying qualities issue is on here. This past saturday morning I was up fora while and re-explored the slow flight qualities. Just for curiosity I timedmy first minute of climb and had nearly 800 feet. It was in the 30s and Iwas fairly light. Anyway I went on up to 3000 ft agl and decided to cruise aroundfor a while at 35 mph. I tried stalls in several configurations. Withand without power. In and out of them, repeatedly. As long as the turns arecoordinated the airplane behaves remarklably well. If you swing the nose aroundsome as you are bumping the stall it will softly fall off on a wing. I'm sureif it was allowed to go further it would just keep on going, but the airplanejust really talks to you and conveys what it is planning to do. Ya just kindahave to listen. Anyway, just thought I'd throw my plug in for how fanastic of an airplane the Pietis. Mr. Pietenpol sure knew something when he designed it.

I've got my fuse sides completed and all dimensions are per the long fuse plansexcept for the angle of the rear seat back and the following diagonal brace...I moved the top from 31" to 34" (+3"). Currently, both sides are set up paralleland square so that I can start installing the cross braces from front toback. I've got a few pieces cut, but before I commit to gluing them into placeI would like to confirm a couple of dimensions... The white ash cross struts... according to the standard fuse plans, the measurementsto the center of these cross struts are 10" and 37.5" from the firewall(as illustrated in image 2). This indicates that the front cross strut is installeddirectly between the junction of side braces 2 and 3, and the rear crossstrut is installed just ahead of the junction of side braces 4, 5 and 6, correct?If so, then I must need to transfer this thinking over to the long fuse plans,which do not illustrate the placement of any of the cross struts. I assume thatI must use the 12" measurement from the firewall since that is where side braces2 and 3 meet (see image 3) and the rear strut would keep the same 27.5"measurement from the front strut (39.5" from firewall), in order to jive withthe landing gear measurements. In short, it looks to me like the landing gear is shifted two inches towards therear for the long fuse, correct?--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/stan ... ______Date: Wed, 6 Oct 2010 12:02:08 -0700 (PDT)

MarkWhat you want is 28-3/4 inches between the center of the two ash pieces. Thiswill keep your wing struts parallel. Install the front one between braces 2 and3 like you said and then measure back to get the location of the other ashpiece. On my long fuselage this occurs about the middle of the front seat andwhere the joint comes together.http://www.westcoastpiet.com/images/Woo ... G_1684.JPG In the picture you can see I had to add a piece to the back of the ash brace alreadyinstalled, I believe when I originally installed the ash cross brace Ifollowed the 27-1/2 inch measurements on the plans.Chris--------ChrisSacramento, CAWestCoastPiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 6 Oct 2010 13:15:37 -0600Subject: Re: Pietenpol-List: Fuselage - Long vs Standard

JimThe picture was taken when the fuselage was upside down (inverted) while Ibuilt the landing gear. In the picture you are actually looking up into thefuselage. I wedged the stick between the garage floor and the fitting tohold the fitting in place while I drilled holes from the other side. It wasa rather simple solution to a tricky problem of clamping the fitting wherethere is no place to clamp.ChrisSacramento, CaWestcoastpiet.com-----Original Message-----
