I have clear lexan for it. Almost to spar. Just enough back for space for pulleys and cables. Clif The flops I've seen in person tend to be only the length of the aileron but I'm wondering why couldn't a guy take the flop all the way to the rear spar. I plan to cover the flop with tinted lexan for better visibility in turns. The ones I've seen also seem to be only about 2'-0" wide or just a shade over but I'm thinking I might make mine the entire width of the center section. Has anyone does these ideas before or have any learnings or (opinions)?

The rear cockpit is narrower, and the longerons are 1" wide apiece, so the shoulder width is something less than 22". And the wind is blowing. And every time you look down to check the map or fiddle with the computer, the plane changes heading by 45=B0. It all sounds doable until you try it. Having flown mine from North Carolina to Brodhead 3 times, Sun 'n' Fun once and Dulles Int'l once, I won't do it without a good GPS - it's just too much trouble. CAN I do it? - Yes. I flew a J-3 Cub from Tennessee to Texas with nothing but a compass and chart, but if GPS had been available ten I certainly would have used it.

The angle bracket that the shrouds attach to on top of the engine should be made of steel. It gets trapped under the top cylinder base nuts and has to remain tightly torqued. If that bracket is aluminum over time it will relax and reduce the torque on those top nuts, which are required to hold the cylinders on. My brackets are .050" thick 4130 steel, with nutplates to attach the shrouds and those are the only parts on the whole shroud assembly that have given no trouble.

Another was to reinforce the leading edge of these things somehow (a wire-rolled edge, a larger-sized formed edge, or maybe an additional stiffener piece) to keep it from moving too much. It kinda reminds me of my backpacking tents (with the hoop forms) and how they react in a wind. Jack's right - These things really do get pounded in the propwash. Steady force is one thing, but the pulsations are the killer because they make things move.

I will admit that I *do* use my iPhone with MotionX GPS app ($2.99) to get me from point A to point B from time-to-time, but now that I know the area better, I generally just use it to log my flight path to see how much time I've spent flying. The battery life on the iPhone is pretty short when you're running a GPS app in the foreground, so I bought an xPal Energizer 18000 battery pack. It's got 18000mH of power which will run my iPhone continually for 50+ hours between recharges. It weighs in at 17.5oz (0.22kg). I mount it on the side wall of the fuse with velcro tabs.

You will need to line it with sheet metal, rubber or nylon immediately. If you make your window from tempered glass ask the Glass Co. for "salvage plate" and have several cut right off the bat. Salvage plate is exactly that...salvage from storefronts. It is normally cheaper. Depending on what you are blasting and the amount of ricochet....you can frost a window over in a couple of hours. You might want to price out the components and then with that budget watch Craigslist. You can pick up a nice used Trinco pretty reasonable right now. As always you will have more $$ into the homebuilt unit than you initially think. -------- PAPA MIKE Read this topic online here: http://forums.matronics.com/viewtopic.php?p=304196#304196 ________________________________ Message 23 ____________________________________ Time: 09:08:54 AM PST US From: shad bell Subject: Pietenpol-List: Avionics thoughts, and corvairs What are these avi-onicals y'all is talk'in bout?- I got one of dem brand new paper ground pictures that folds up, and one of dem direction indicato rs ya dumps your ex-try moonshine in to, I aint got too dis-con-bobulated y et.- I even knows where to drive to, to picks up da pieces that falls off my engine.- - Shad -p.s.- a gps is nice for low visibility or emergency use, and for detec ting un-noticed head/Tail winds - Do not archive!!=0A=0A=0A ________________________________ Message 24 ____________________________________ Time: 09:19:26 AM PST US Subject: Pietenpol-List: Materials List From: "K5YAC" I know this wasn't requested, but with several new interested parties on the boards, I figured I'd offer a list that has been very helpful to me. This might be published elsewhere, but it was forwarded to me by someone here (probably Markle) and I reference it often when trying to decide which pieces to use for certain assemblies. The original list that I received was compiled by Bob McKinley. I think he must have been one of the Ohio guys as there was a Buckeye Piet sketch in the margin, but I'm not sure. Certainly someone here knows of him. The list I recieved was a scanned image of an old document that was typed up on a typewriter, and some of the notes were difficult to make out. If I had that file I would offer it too, but I'm afraid I've deleted it, or at least misplaced it among all my Pietenpol goodies. Anyhow, I used Bob's list to inventory my wood kit when it was delivered. It was pretty close to right on... the spar thickness was different (3/4" instead of 1"), and Aircraft Spruce offered a couple of additional parts in the tail section (I've noted all of these on the new list), otherwise it is very handy in helping to sort out all the parts one might need to assemble this airplane, whether you choose to purchase a kit or cut your own parts.

I made a very serviceable cabinet out a medium large cardboard box, half a roll of duct tape, a 2 foot square piece of scrap glass and a fifteen dollar blast gun from Harbor Freight 7 years ago. Still using it. Just be sure your air compressor will put out sufficient volumne and don,t cheap out on the blast media. Glass beads work best.

Back then most towns had a passenger RR station, and I believe many, if not most had the name of the town on the roof of the station, to help guide aviators. CL must have picked up a few other tricks before his 1927 hop across the pond. I recall the following, but the details may not be right. He was about four miles off course from his first European landpoint in Ireland. That is smack on. His dead reckoning of interim points was on brown wrapping paper on folded cardboard, posted in pencil each hour. (The pencil was lighter than a pen and less likely to fail.) His plotted course was NOT a straight line, as he was adjusting for winds and compass deviation, and for what he believed he had covered empirically (actually). Between that and fuel management, icing, and staying awake, he was fully occupied. IT was then, and still is, absolutely amazing.

From: Dan Yocum Well, I bought the "new" style oil pressure valve spring and installed it, tonight. Then I fired the old girl up and watched the pressure spike at 60psi while it warmed up. After about 5 minutes the temp was at 40C and the pressure was on it's way down to 50-55psi. I took off and tooled around the field for about 40 minutes. The temp got up to 75C and the pressure never got below 39psi with the throttle at the firewall, 2300rpm. When I entered the pattern and pulled it back to 1400 the pressure dropped to 28. Pulled up to the hangar and pulled it back to idle, pressure dropped to 15. I pushed the throttle up to 1300-1400 and the pressure "popped" back up to 30-35. Back to idle, back to 15psi. Back to 1300, back to 30. So, the new spring definitely helps. But, is it a bandaid? Or is it a solution that will work until the pump gets worse? I'll spend a couple more hours in 'er in the next couple of weeks, but it looks I'll be flying to Brodhead. :-D Dan -- yocum137@gmail.com ------------------------------------------------------------------------------------- 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.
