I believe the A75 also had a waffle pattern of ribs cast into the underside of the pistons to aid cooling. This is what allows the higher operating speeds, essentially alowing continuous operation at the A65's redline.

From: "Phillips, Jack" Hey Jim, Check out the Fighter Factory at the Virginia Beach Airport. http://www.fighterfactory.com/airport/index.php. They've got a nice collection there including at very nice P-51, a Spitfire, a TBM Avenger, a PBY, A Messerschmitt, a Tiger Moth and many others, all flyable. There is also a very nice aviation museum at Hampton Roads. Check it out at: http://www.vasc.org/. I was surprised to visit there and find an old friend, YF-16 number 1, which I spent an awful lot of time working on when I was a young engineer working at General Dynamics in Fort Worth back in the 1970's. Or you could drive 3-1/2 hours southwest and come to Raleigh and I'll take you flying in my Pietenpol.

Jim, I lived in Norfolk for 30+ years, and I would suggest that you check out the VA Air & Space Museum in downtown Hampton (across the water, as they say down there). Also, not aviation related at all, but the USS Wisconsin is docked in downtown Norfolk and is open for tours, quite an awesome ship. Of course, if you are in the flight path of any of the approaches to Oceana NAS, you'll hear the "Sound of Freedom" for your entire visit :).

Both Bernard's later recommendation on this, as well as the experience of probably hundreds of builders proves this. The 1" spars, like much of the rest of the plane, is an over-build. Glue 1/2" wide strips of 1/8" plywood vertically on your spar (both sides) at each rib station and your ribs go on perfectly. If you are using Grega ribs, you should cut down your rear spar to fit that width. Kip Gardner On Sep 9, 2007, at 11:00 PM, Brian Kraut wrote: > > > I have a very interresting Sky Scout project.

Textor" Morning friends, Had a great weekend building. I finally figured out how to get the second bend in the cabane fittings. Used a makeshift brake held between a vise and large C-clamp. This portion of the project has been daunting, so I was glad to figure it out. To see a picture, it's on www.textors.com , under Piet Project towards the bottom of the page. Have a good week! Jack Textor Des Moines www.textors.com ________________________________ Message 8 _____________________________________ Time: 06:34:45 AM PST US From: "Oscar Zuniga" Subject: Pietenpol-List: Continental A-75 cruise rpm question Ken; I have acquired an A75 that is being gone through right now so I'm learning about them. As I understand it, the main difference between the A65 and the A75 is that the 75 has a hole drilled in the rod big ends to increase the oil flow, allowing the higher RPM needed to get the additional HP. There is some vagueness as to whether the venturi size in the Stromberg carb needs to change as well, because the Continental service letter does not mention it for the A75. They do clearly show the 1-5/16" venturi needed for the C75 but it has increased displacement (larger bore) and develops its rated HP back down in a lower RPM range than the A75. My assumption is that the A75 should use the same 1-1/4" venturi as the A65. I guess what I'm saying is that if you operate your A75 at its rated RPM (full power at 2600 RPM, cruise at 2350), you should be getting rated HP and still be OK on lubrication. I noted from the engine specs that the C75's max and cruise RPM are the same... 2275. There is no substitute for cubic inches ;o) Be sure you check your mechanical tach with an optical one though. I found that the tach on 41CC was reading about 200 RPM high at cruise RPM, meaning that I was leaving power on the table some of the time.

My first thought would be that you would put plywood on the surfaces that the fittings attach to so that they are full height and the fittings would go over the covering. On the uncovered tail surfaces I have they are already varnished and there are slight indentions in the wood where the fittings were obviously bolted on previously making me think that the builder had intended on having the fittings under the covering with the tabs sticking out of slots cut in the covering and I guess the bolt heads covered over giving you an ugly bump. Is this really how other people do it or should there be plywood building up those surfaces, not to mention reinforcing the areas. Sorry for all the newby questions. If someone could point me to a good builders site with lots of pictures I could probably answer most of my questions myself.

Loaded to near gross weight on a 90F afternoon with high humidity, she climbs about like she used to solo, well worth the $$ for the prop in terms of get me over that tree at the end of the runway value. First chance we get, my buddy with his C-85 powered Cub and I will square off in a proper rate of climb comparison. I'll bet I can give him a run for his money now :-) BTW, she gets a diet of 100LL and the recommended Marvel Mystery Oil. 100LL because I've had problems with alcohol and water in the local mogas, and the MMO because it can't hurt, and lots of folks with more experience than I swear by it.

I don't have a lot of free time and I get a good deal on my friend's CNC turret punch so I am going to just draw them in CAD and have him punch them out. I was thinking that I might be able to sell some other punched parts to offset my setup cost some. Is there anyone already selling pre cut steel parts? Is there much demand for it? It is a particularly good method of doing things like the wing attach fittings where you need a bunch of them and you want all of the bolt holes in exactly the same place on all of them. For things like the 90 degree bent tail attach fittings you are better off just starting with strip stock, radiusing the corners, bending, then drilling the holes in place than having them punched and trying to bend them exactly the same and having the holes come out the same on the left and right sides.

My wife had never flown in a light airplane before, and through a confluence of coincidences she was able to take her first flight in "The Last Original" with the woman who used to own the airplane years ago, who is a friend as well. This was particularly perfect, as last month we received our own set of Piet plans, and we are going to use the Corvair. And her opinion of the flight: she loved it! Needless to say, I'm ecstatic. She was enthusiastic about it beforehand, but now she knows she likes it, so she is even more gung ho about building and flying our own Piet. I'm a lucky man. :) Many thanks to Bill Knight, who was gracious enough to allow her to go flying in his airplane. Later on he also allowed me to climb into the airplane and see how it fit, and I must say that I was pleasantly surprised that I was not cramped. I'm not extra tall (5'11"), however I'm not small (220, 44" chest). Reading some of the postings about cockpit width had me worried, thankfully for no reason. Anywho, on to my question.... I've been reading through the builders manual, and thinking about how we will convert our Corvair. I rather like the idea of sticking to Bernie's conversion. It's relatively simple, has thousands of flight proven hours. Plenty of time before we completely make a call on that. One of the things in the process I was wondering about was the design of the intake manifold. Bernard indicates that the intake manifold is jacketed, and engine oil is circulated through it in order to heat the manifold, and cool the oil. If it's not an utter bear to construct, it would seem to be a good way to heat the manifold to reduce the susceptibility to carb ice. Unfortunately there is no picture or drawing of this that I have found, and I do not know exactly how one would go about fabricating such a setup. Might anyone have an eye-witness description in a bit more detail, or better yet some photos? I wish we had been able to pop the cowling on the "Last Original" at Brodhead, but we didn't ask at the time because we did not want to be a bother with everything else that was going on. Maybe on the next trip up.
