Cc: Boatright1(at)aol.com, FWWhitaker(at)worldnet.att.net Thanks for all the thoughts on this, and please keep them coming. Our Piet had a huge trim tab, but for the opposite problem. The former owner mainly flew solo and was a big, tall guy. He had problems with nose up, not nose down. Obviously we could have left the tab on and simply bent it the other way, but it was so huge and ugly (and only on one elevator!) that we pulled it off. Even solo we're getting nose down, so we still need a trim solution. > >I've been wondering the same thing. I don't think I've ever seen a >Piet with a "bendable" trim tab.

The recent interest in rib jigs, staples vs nails, etc.has prompted me to post a picture of a rib jig I made while building an Airbike wing. I didnt use nails or staples. Instead, I held everything in place with toggle clamps. What I like about this method is that you can put the gussets on both sides at the same time...Cuts glue-drying time in half. The price you pay is that the gussets need to be cut very uniformly, which you can do by stacking the layers of ply and using a metal template on the top of the stack.

Dear Brian, I can at least speak for OSH. I took my oldest to Airventure in 2003 (he was 13 yrs old). We borrowed my buddy's pop-up camper and camped at Camp Schoeller. No kidding: there were at least 20,000 other tents/pop-ups/5th wheels/drive-arounds/mobile palaces at Camp Shoeller that week. At first, we felt alone-not knowing anyone else out there. Like most campground camping experiences, as the week progressed, we came to know the campers around us. After a big day inhaling aircraft in the sun, we'd retreat to, what we came to call, home and fire the grill for steaks and corn. So camping at OSH is not a trout-filled dream. But it's a great place to hang your hat and meet fellow aviation nuts like us.

Say Fred, Have you looked at the new mountain bikes with front disc brake set-up They have an internal spring that return the brake back to the open without any exposed brake springs.

Jeff, We had the same problem with NX18235 when it first flew. It required about 6 lbs. of aft stick pressure to maintain level flight. One problem we found was the elevators were rigged slightly uneven. When this was corrected the required aft stick pressure was reduced to about 2 lbs. The remaining trimming was taken care of by adjusting the stabilizer turnbuckles.

Subject: Re: Pitch trimming
First, a few observations: The Pietenpol Airfoil has a LOT of negative pitching moment, requiring more down force on the tail than other types of airfoils, which is another one of the things that cause this type airframe to be very draggy. Trim drag is the amount of Down force applied to the tail, to maintain level flight at a particular power setting. Another thing that aggravates the negative pitching moment, is the actual weight of the flippers, which adds to the nose down characteristic. The pitch axis is dynamic on Pietenpols, similar to any other aircraft, in that trim drag changes with changes in C of G. If you carried all of your fuel in the wing (as designed), the C of G changes very little, hence, no need for adjustable pitch trim. Choices: Adjusting the leading edge of the stabilizer down, to attain a nose up attitude would be a ground adjustable trim method. If you use a cowling fuel tank, an in flight adjustable trim tab, or some type of spring / bunji applied to either the bell crank, or the stick, may be used. In my mind, I don't like anything extra - if it ain't there, it can't break...kiss method. I had similar characteristics as you (and many others), in that I had to hold back stick, to maintain level flight when the C of G was at the forward positions - full cowl tank. The thing I did was to experiment with a Fixed trim tab on the inboard trailing edge of each flipper. This negates the weight of the flippers, and has no moving parts. I used balsa wood trailing edge of R. C. airplanes, available at hobby stores. Each one is about 5" long, and 1 1/2" wide, and blended right into the trailing edge of the flipper. I experimented with the angle of the trim tab, and after many test flights, found an angle that would be hands off, with the C of G in the mid to forward range. To make dynamic pitch trim changes, I simply adjust the power setting. I have pictures of my trim tabs here : http://nx770cg.com/Fuselage.html Chuck G.

Hi, I have the disassembly video. Like the stage 1 assembly video it is good. He talks you through deciding what to keep and what to discard and gives you a heads-up on things that are problematic and what areas people tend to break when they do it incorrectly. What I value most in all of his materials is that he presents it in a way that reduces the process of disassembly and making the conversion to a straight-forward process that any careful somewhat mechanically inclined individual should be able to reproduce. For the $20 I spent for the video I think it was worth it. I'm not a mechanic but I am a careful, mechanically inclined individual.

Fred when choosing brakes bear in mind that with large diameter wheels it takes a lot of brake to stop it (airplanes quit using large wheels about the same time they started using brakes). Look at the size of the front disc on a Harley-Davidson. Most go-kart brakes have pretty small discs (because they have small wheels). I have regular 6" Cleveland hydraulic disc brakes on my Pietenpol, with 21" wheels. The brakes will stop it (gently), and will hold it for a run-up but cannot hold it at full throttle. My advice would be to use the largest diameter discs you can find.

I have thought about using Mtn Bike disk brakes. The largest I have seen are 203mm or about 8", but another factor is that the pads probably don't have as much surface area Clevland pads or even small go-kart pads - so the friction coefficient between the pad and brake will be less I'll do a bit more research and try to figure it out. Is there anyone that has used MTB disk brakes on a Piet? Hydraulic or Mechanical? What size wheels? What size disk? Shimano, Avid,.....? Kirk >>> Jack.Phillips(at)cardinal.com 04/26/06 9:18 AM >>> Fred when choosing brakes bear in mind that with large diameter wheels it takes a lot of brake to stop it (airplanes quit using large wheels about the same time they started using brakes). Look at the size of the front disc on a Harley-Davidson. Most go-kart brakes have pretty small discs (because they have small wheels). I have regular 6" Cleveland hydraulic disc brakes on my Pietenpol, with 21" wheels. The brakes will stop it (gently), and will hold it for a run-up but cannot hold it at full throttle. My advice would be to use the largest diameter discs you can find. Jack Phillips NX899JP ________________________________________________________________________________

Hi Fred, I have 19" spoked wheels on mine. I use a 5" mechanical drum brake from Kart World out of Cleveland, OH. The brakes are very simple and low profile. They are cable actuated and are attached to hand levers under the instument panel. The hand levers are just aftermarket motorcycle handles from a local motorcycle shop. They are placed close enough together that I can hold both of them at once for the run-up. They are just enough to barely hold the run-up. Sometimes, by the time I finish the run-up I've crept a foot or so. I can deal with that. The only other time I use them is for taxiing. They seem to be okay for that. A liitle planning ahead is a good idea too.

Bill... The wheel covers are just regular doped fabric. I made an aluminum disk/ring at the hub on both the inside and the outside. Glued the fabric to it then positioned it over the hub. Then just glued the fabric around the inside edge of the rim where the tire mounts. Made sure I had a few inches of glued area around there. Then just finished it like any other doped fabric. Tire mounting is not fun! Lots of soap, little wood wedges, cussing, and sore fingers. I am not looking forward to replacing those things some day. I'll have to make sure the kids aren't around when I do!

Subject: Re: Trim tab was pitch trim saved Sean Tucker's life
Date: Apr 27, 2006
I use two ground-adjustable aluminum tabs on the elevators of my Pietenpol. They are fastened to the underside of the trailing edge with a couple of screws and zinc chromate putty (as used in aircraft floats) is used to seal the screw holes against moisture entry. These tabs are adjusted to trim for level cruising flight when the forward fuselage fuel tank is 1/2 to 2/3 full. With a full tank, the plane is nose-heavy and I trim by increasing power. As the fuel burns off (and the a/c becomes lighter), I reduce power as required to trim for level flight. This works quite well, but I really would like to have a controllable elevator trim tab as a backup in case of elevator control failure. Years ago, I planned to incorporate one but never got around to doing so. I have flown a Piet with such a system and it worked very well. The trim tab was on one elevator only, and was added after the aircraft had been flown for several years.

Glenn, Are you talking about a hydraulic shop press? Something like this? (attached photo)... Not too sure how handy it would be for this project. Unless you have access to a metal shop with shear, brake press, punch press, notcher, etc (like some of us are fortunate enough to have), I think the most useful metal working tools for building a Piet would be: 1. a metal cutting bandsaw 2. a drill press 3. a 4" angle grinder - with sanding discs and cut-off wheels (attached photo) 4. a good big vise with some metal bending dies (see this link) http://www.leevalley.com/wood/page.aspx?c=3D2&p=3D32011&cat=3D1,43456,434= 07 5. and the bench mount belt/disc sander mentioned by others Most of the bending on the Piet is narrow strips (or very light gauge stuff), so the vise-mounted dies should be adequate. So, unless you have other, non-Piet uses for a shop press, I would spend my money in other areas. Bill C. ________________________________________________________________________________

If you can find a metal working shop near your house that can shear up some strips of .060 and .090" thick 4130 sheet for you ( shear WITH the grain lettering for safe/good bends) of various plans-required widths, you'll save so much hassle from having to band saw them up, not to mention saving the price on what Aircraft Spruce or others charge for 4130 strip material. If you look at the plans you really only need about 3 or 4 various wide strips of 4130 sheet material to build the entire airplane. It is WORTH looking around for a shop near you who has a shear capable of cutting .060 and .090 sheet ! Mike C. ________________________________________________________________________________

Glenn, If you don't already have them, get Tony Bingelis' books (I thought I'd say that before Mike Cuy did). I think the second one "Sportplane Construction Techniques" is the one that shows step-by-step how to make aircraft fittings. All you need are a good vise, a good hammer (I used a 2-1/2 lb sledge) and an "anvil" made from a piece of 1/4" steel with a variety of bend radii ground onto its edges. It is helpful to have a metal cutting bandsaw (I bought one from Grizzly for about $200 that worked great) and I used the sanding disc on the side of my belt sander quite a bit, but it is possible to do everything with handtools - hacksaw and a file. Fittings seem to be a pain at first but by the time I finished building the plane, the metal work and welding was my favorite part.

Another book that is useful is the EAA's Aircraft Welding book. There is a one-page article in it written by (who else?) Tony Bingelis in which he explains how to make the flared ends on tubing that are used in a number of places on the Pietenpol, such as the spreader bar on solid axle landing gear, and the pushrod that goes between the joysticks on the torque tube. I used this technique on my jury struts as well as the pushrods I used to connect my front rudder pedals to the rudder bar (so I didn't have to use return springs), and the pushrod connecting the front and rear throttles.

I hear that! I basically work on the project on weekends. To justify a solid day of the weekend on the Piet, I feel an obligation to be a husband the other day. (1 day a week!!!) Son is now in college so no hockey/lacrosse to cause further time away from project. I have learned to tuck Piet time into free hour blocks that are not consumed by other things. Early mornings (no power tools) and late evenings are good quality Piet time. You will see shop lights on well into the morning hours if I'm on a roll.

I will c= omplete a flow test as discussed in previous valued comments found in the archive. Thanks all, John Fuel related problems are the most common reason that airplane engines stop running. There are a LOT of factors to consider when designing a fuel system. Some of which are: 1) The outlet should be the lowest point in the tank, in order that ALL water will find it's way out when the plane is in the static laden position (sitting tail on the ground). 2) There should be a removable finger screen in the outlet, to catch all th= e garbage that seems to find it's way into the tank. 3) The mounting system must be able to sustain at least 3 times the weight of the total fuel capacity. 4) Quantity indicator must be reliable, and be able to monitor it in flight= - Not Electric..too unreliable. A fuel cap with a cork & wire indicator is simple and easy to make, and should also include a 90=BA Ram tube (1/4" tubi= ng) facing into the prop wash - to maintain a little bit of pressure in the fuel= tank. 5) Fuel shut off valve on Certified planes must be behind the firewall, but= I put mine on the front of the firewall before I realized that fact. My reasoning is that there is No portion of my fuel system inside the cockpit a= rea - no leaks can find their way into the cockpit. 6) 3/8" fuel lines to maintain enough quantity flow. 7) Gascolator Must be in the lowest point in the fuel system (even lower than the carb), to collect water. However, it Must be above the lower edge=20= of the firewall, in case you wipe out the landing gear, it will Not rupture the= fuel lines. For my cowling tank, the bottom is sloped forward, so when the plane is in the static laden position (tail on the ground) any drops of water will dr= ain out of the tank, into the gascolator. No fuel lines or fittings are in the front cockpit. I installed a fitting on the top, at about 10 O'Clock positi= on (viewed from the cockpit), to fill it from the wing. My quantity indicator=20= is a cork & wire, similar to a J3. I made my fiberglass cowl tank with the flanges on the sides of the tank= , to rest on the top of the longerons. I put a lot of time and thought into the mold for the tank. I made the inlet on the top left side, (at about 10 O'clock pilot's view), and made a fiberglass blister stand outboard of the cowling, to prevent possibility of leaks entering the cowling. The outlet i= s also outside of the cowling shelf, and points forward. There is an EL fitting, t= hen the 3/8" ball valve that is cable operated. The bottom of the tank slopes forward, while in the tail down attitude (as it sits in the hanger), so any=20= water in the tank makes it's way all the way out of the tank, and into the gascolator (a very important design criteria). I used the aluminum 'weldabl= e fittings' that AS&S sells, glassed in, at the inlet and outlet. On the outl= et side, I modified a finger screen, so it threads into the 'weldable fitting', by taping the o.d. threads, and then the 90=BA EL threads into the 'weldable f= itting' on top of the finger screen. As a result, I was able to squeeze a lot of fu= el in the cowling tank. It holds 10.7 gals. I didn't know how much fuel it would hold, till I did a leak test, by setting it up at the gas pump, at the= angle the tank sits in the plane, and put one gallon in at a time, then dipping a stick into the fuel, to mark off each additional gallon. That's how I made=20= my 'Fuel Quantity Indicator'. I topped it all the way off, then put the full tank in my trunk, brought it home and left it sit for 3 or 4 days to check f= or leaks - No Leaks !! My wing tank holds 9.8 gals. so my total fuel onboard=20= can be 20 gal. That's a lot of fuel. I don't think I could sit there long enough to burn that much fuel at a time, but on the way back from Oshkosh, I= did do one 4 hr leg, and two 3 1/2 hr legs, and still had plenty of reserve. But you know what they say - "The only time you have too much fuel onboard, is w= hen you're on fire !!"

I used 1/16" Plywood Plates, 1/2" wide X about 2" long, the way it shows in the plans, then feathered each end down so it didn't leave a bump. With the fabric on, you have to look pretty close to see the plywood strips. After pre-fitting everything, I used rubber bunji chords to hold the trailing edge in place while the adhesive cured at the butt end of the ribs, and the plywood strips. I used T88 epoxy throughout the airframe. No problems anywhere with the adhesive, after almost 280 hrs flight time. Chuck G.

Use a horseshoe-shaped piece of 1/4" plywood glued to the spar face and position the end of the 1/2" x 1/2" brace in the 1/2" x 1/2" opening of the "horseshoe". This setup captures the brace and the relatively-large glued surface against the spar face provides lots of shear strength. It has worked fine on my Pietenpol for nearly 36 years. A simple butt joint will not work, against the spar face or against the inside of the tip bow, where extra glued area will be needed to hold the brace in position against fabric tension.

Rick H., I didn't use the "horseshoe" plates on the 3/4"x 3/4" compression struts on my Pietenpol, but they could be employed there to help hold the struts in position. I used the triangular (sort of) gussets as shown in the plans and they seem to be satisfactory for this purpose. If you wish, I can send you (off list) a photo showing my Pietenpol under construction with a view of the compression struts, etc. It is a black and white photo and was taken, in 1969, by a friend who was the co-builder of a Pietenpol in 1931 (when he was only 16 and the other guy was just 17!).

Hi Guys... This is my tailwheel that Chris was asking about. I thought I'd post a picture. It is basically just a wheel added to the plans skid. The wheel is a 4" unit from Wick's. The fork is welded up and has a vertical steel tube bushing into which an AN8 bolt is pressed (1/2" bolt). This is the vertical shaft of the fork. A welded up 'T' tops it off which is connected to the rudder cables. An AN3 bolt goes through the AN8 bolt in the fork and in the 'T' to lock everything together. The shaft of the fork fits into a bushed tube that is weled to the A-frame. Plates are welded top and bottom of that. The spring is from a fork tube from the front of a wrecked motorcycle. $2.00 from the local junkyard. It started out about 2' long and had to be cut down. The cables connect to the rudder cables under the seat with #10 electrical wire connectors. The tubes tend to want to twist when turning left or right so I plan to help that by welding a cross piece near where the tubes meet the fuselage. It probably isn't the best idea out there, but seems to be working for now and is fairly light in weight.

I have two turnbuckles on the rudder horn, and four turnbuckles at the Flipper horns. Like you said, easy to get to, adjust, and inspect. Eventually, I'm going to change out the rudder cables, and instead of turnbuckles, I'm going to use two straps made from .060" 4130, which will be about 7/16" X 1 1/2"...similar to motorcycle master links. I have a local shop that will shear 4130 for me. I can make a dozen of these things for the price of a single turnbuckle, and vary the length between the holes of each pair by a few thousandths of an inch, then find the ones that take the slack out of the cables. List the length on the part, and keep the rest for future adjustment requirements. I'll use #10 AN bolts, with locking castle nuts. I'll place them at the rudder bar, instead of back at the horn, to save a little weight on the tail. I haven't used this method yet, but I don't see any reason why they couldn't replace all the turnbuckles in the control system, because None of the control surface cables on the Pietenpol should be tight...just take the slack out, and that's it. Before doing this, It would be interesting to compare the tensile strength of these straps, with that of a turnbuckle. Chuck G.

Don Emch I also added a tailwheel to the plans type tailskid, after about 35 hours of operation. When making changes, Nothing is free, everything is a tradeoff. In this area, the tradeoff is the deck angle (static laden) of the three point attitude. With the skid, the tail was lower, and I was able to do full stall landings much easier than now. With the wheel back there, the tail is higher, and at 3 point touchdown attitude she hasn't yet reached the 'Critical Angle of Attack', and the wing is not yet done flying, and a bounce sometimes occurs. This is the reason I located the tail wheel Behind the skid plate, as opposed to under it - to get the tail as low as possible. On the grass, 3 out of 4 landings are greasers when I touch tail first, but Every time I have tried full stall on the hard surface, she bounces, even when I touch tail first. For this reason, I have to wheel it on the hard surface, and put up with the long roll out. I much prefer full stall landings.

My deck angle is already a little high, I think around 15 or 16 degrees, but not sure I'd have to measure again. The plans split axle gear is taller than the wood straight axle gear. The wood gear usually is used with the spoke wheels. I decided to used the spoke wheels on the split axle gear. So... this makes it kinda tall. I've seen Piets go from one extreme to the other in the deck angle. I seem to get close to full stall 3-points. Just another area where little changes lead to unique airplanes!

Don-- I'd have to concur with Jack Phillips in that pavement landings are somewhat more challenging in the fact that you get faster response directionally. Nothing dramatic, but it makes you concentrate more on being in good alignment on touchdown. To me, using the right tire pressure for pavement can make a difference in wether I rebound into the air or if she 'sticks' but then again that factor is based on how hard you hit as well:) I had no real concerns as the straight axle gear leaves no room for wheel castor and camber errors as does the kind of gear you built. If your gear is true, and more importantly each wheel tracking true to the other, you should find pavement pretty much a non event.

I'd like to add one item to Mike's post. I try to avoid the seams in the runway if possible. I've landed on a couple where the joint in concrete has caught on the tailwheel. Also I have found carrying 1100 rpm all the way down makes a bounce less likely or a sudden flop onto the runway in the full stall landing.

Clif, The first thing you would have to do is figure out the amount of urine stored inside the bladder. Then applying some mathematical calculations, you can determine the weight of the uric acid versus untainted liquid water to arrive at a weight per ounce. Then subtract that number from 6.6033 to determine the correct amount of ballast within the bladder. In the sagittal plane you need to calculate the arm for weight and balance to find a starting point of adjusted movement of weight relative to center of gravity in the aircraft and the human body. Then and only then can you get the true accurate number of forward weight deflection within the cabin of a pilot who has to pee......

Hi Ken Perhaps you hit on something. Yachts are using active trim tanks usually side to side to reduce heel. Perhaps you could install a small soda bottle fore and aft with a a manual trim pump in the cockpit. Putting the tank as far aft as possible would give you a good amount of moment. You could even have a third port in the cockpit so you could have a little drink while flying along. It could be a problem in the winter with freeze up but I'm sure some suitable ducting could be worked out. Could call it the wet trim system.

Don, I used to mess with the trim on a Cessna. Trim it perfectly, then lean forard and put your hands over the inst. panel. Down you go. same with leaning back in the seat with hands over head. Up you go. Here's something that I've tried, and not too many had heard of it.....Trim out a plane at a certain alt. Say 1000 ft. Now don't touch the trim, but pull up and climb to 2000 ft. Let go of the stick/wheel, and it will slightly nose down and slowly lose altitude. The rate of decent will slowly diminish, and it will settle back exactly at 1000 ft. So the trim will be different on any day for any density altitude. Neat trick. Also flew my old Fisher 404 from a nearby airport back to my home airport (about 15 mi) hands off, just sticking my fingertips out each side of the windshield, as needed, to turn and correct heading.

Don, Yeah, it seems that when you land on grass, it's both the grass and you that interact for the landing. But on pavement, it's all yours. Just go to the airport on some evening where there are no spectators. Spectators ruin the concintration I've found that when landing the Pietenpol, to give a little power (about 1000 rpm) at or before the time of the flare, so you don't get the drop. I had to get over the fear of the end of the runway comming up. Thought about it all the time, and that ruled the landing. but when I was aware of it,,,every time I landed, I'd see what runway was left. There was always plenty. So then I was forcing myself to not worry about the runway left, and about the quality of the landing. Now at the flare, time slows down, and with some power on, I feel, feel, feel, for the grass. they are alot better this year. I like the comment that the only difference between a grass landing and pavement landing,,,,,is that on pavement, you have to spit out your gum first. Talked to the owner of a parachute jump school about this. I'm 58 so he seemed to be a kid. But he owns a Cessna Caravan, Super Otter, and a Cessna 182.

To all Corvair flyers: This afternoon I visited an open house at a local FBO and float storage business at Lake Hood here in Anchorage. I went specifically to find an A&P that had been identified as an EAA technical advisor who works there. After asking him if he would be available to help me with my project he said "sometimes," and asked what kind of project I was working on? When I told him about the Pietenpol project, and that it came with a turbo-charged Corvair engine, he immediately said, "I am not a fan of automotive engines in aircraft, those Pientenpol builders seem to like them, but then again they are flying over farms and fields, and up here we don't have any of those, so if your engine quits..My advice to you is to get a 0-200 or an 85 horse engine for $15-16,000 and forget about the Corvair. My question is how many of you using Corvair engines have encountered mechanical or carb ice problems while flying with this type of engine, and been forced to land as a result of either?

Got the same type of response from the ABDAR and various folks in my EAA chapter. He didn't say he wouldn't do the maiden or assist in his capacity as Tech Counselor but I also got a lot of "encouragement" to abandon the Corvair idea. In fact I was encouraged to abandon the idea of building a Pietenpol which is said is a "dangerous" plane. I think he is just looking out for me since the Piet seems to require a little more skill than the average plane, and although I'm building the plane, I am not a pilot.

Rob, I fly a Corvair since late August of last year, I am still working away on the 40 Hour test period, weather and work have been getting in the way. A few hours in to the test phase I had a engine out and had to make a off field landing, which was no problem as I had enough altitude to find a good field. No damage to the Airplane and a few experiences wiser. The engine out was caused by a fuel starvation problem. I used a 11 gallon wing tank and a 2 gallon header tank, the 2 gallon tank was empty when I landed. ( could hear the fuel flowing back in when I was on the ground) The original system had a ventilation line on the 2 gallon header tank to avoid air in this tank. However in flight this vent would create a pressure on the header tank that stop all fuel from the main tank. The vent cap of the main tank is also in a low pressure area on the wing, which contributed to the problem. I made some fix with a check valve on the header tank vent line ( air allowed out but not in) and re-arranged the vent line to avoid excess pressure. I flew another 4-5 hours this way but was never comfortable with it. A 2 gallon header tank gives you about 25 minutes of airtime at which time you get the urge to land. I finally removed the 2 gallon header tank and replaced it with Piper J3 tank in the nose (12.5 Gallons) it shifted my CG forward which I compensated with changing my exhaust system ( changed the cast iron manifolds for a much lighter header system) Been flying with that setup for more than 20 hours now and have had no problems. My Corvair is a '65 , 110HP Corvair conversion as per William Wynne manual. It is a very smooth and powerful engine, I would rate its reliability as very high, very close to a Continental. If it had dual spark plugs it would be an equal. Still fly with a non nitrated Crankshaft too, although I have a spare one that is being nitrated. If I had a O-200, C90/85 I would have used it,only because you do not have to deal with a 40 Test phase (25 hours if you have a aircraft engine) Of course there is money issue as well, total expense on my Corvair was 6,000- US with all moving parts to new specs, I did not cut any corners on rebuilding the engine. (the crank in hindsight being the exception) Furthermore I believe two more Pietenpols had to make a forced landing last year, both Continental powered, go figure.. It is very rarely the engine that causes a problem it is most likely the systems around it that fail. Hans ________________________________________________________________________________

Good reply. Yes, I have read Wynne's website info and the story by an obvious follower of his, also a journalist. My thinking is, if carb ice is a problem with this engine, then what has been done to thwart it. Wynne makes reference to a joint carb heat device that as you throttle back applies carb heat. I talked with a guy who up here who ran the Corvair in VW buses, and he said they are "very" prone to icing up and also uses them in air boats and more than once has seen ice build up on them, and even wrapped the manifold with asbestos cloth to help the problem.

Note that according to the online aviation databases, William holds an A&P but no pilot ratings. There were two in the aircraft and the other guy was officially the pilot. The plane went down and caught fire, severely burning William. The investigation attributes the accident to carbuteror ice. There's a write-up about the incident on his web site, or you can find the accident report on the NTSB web site. In the last 20 years or so, the definition of 'experimental' has become skewed to mean "a reliable airplane based on somebody else's kit or plans". Because of the proliferation of available kits, plans, engines, etc, this has become an expectation with homebuilders. At the end of the day, YOU ARE THE MANUFACTURER. Years back, I had a casual conversation at Sun 'n Fun with Bob Barrows, the guy who engineered and sells plans for the Bearhawk, about his take on liability. Bob's response was "Here's what I did, and anybody who wants to attempt to try what I did is welcome'. This approach absolves the experimental suppliers from liability, which in turn allows these airplanes to be built at minimal expense. I'm not a lawyer, I've never sued anybody for anything, and I despise inappropriate (my definition / opinion) lawsuits. My concern regarding liability isn't about my ability to sue somebody; it's about my expectation that anybody who engineers something and sells it should have enough pride in it to stand behind their work. On the flip side, that also means me, as the manufacturer of my homebuilt. When I bought William's manual back in the mid-late 90's, he had me sign a liability waiver before he would give it to me (Does he still do this?). In this litigous society, I can't blame William for consulting with his lawyer first (In fact I think it was smart) before selling manuals, but it didn't instill a lot of confidence in me. I thought (and still do) it was strange, having never had to sign a waiver for anything when I bought airplane stuff before, but it certainly rams home the 'YOU are the manufacturer' concept. It also blatantly reinstates the classical definition of 'experimental' with respect to aircraft. Think about it. I've seen scant few quality (my definition, sorry) Corvair installations in aircraft, but they also involved tons of work and skill; way beyond a normal engine rebuild and install. I suspect a good lot of the current crop of Corvair folks are relying too heavily on William's work without verifying all the information for themselves, based on the volumes of 'William says', I hear at Sun 'n Fun every year and see on this forum, and some of the shortcuts I've heard people are attempting. You are the manufacturer. Do the work. If you don't know how, get help until you know everything about your specific engine in your specific airplane. But please don't shortcut the process because it's cheaper, either in money or in time. Lots of folks would like to own an airplane for minimal or zero cost, which is really what this is about. If you could get a good A-65 for the price of a Corvair engine, would you really consider the Corvair? I have an expectation that quality, reliable stuff is not going to be free, so I expect to have to spend enough time, brainpower, and money to put a reliable airplane in the air. If somebody at the airport said "I just finished this plane and I only spent $400 for the whole thing", would you get in it and go for a ride with him? I'd be too busy looking for old gate hinges, lawnmower control cables, used dental floss and house paint. I'm not a motorcyclist, but a long time ago Bell had a one-liner ad for their helmets which stuck with me that said "If you've got a ten-dollar head, buy a ten-dollar helmet". Not this boy. Don't get me wrong; I do like Corvairs and I've owned many (3 right now) since the late 70's. And I do my own work on them. You guys can wax poetic all you want about Corvair engines in aircraft, the Corvair 'Authority', and Corvair Colleges, and hopefully time will prove me wrong (sincerely). But in the interim and until the kinks are worked out, I choose to not be one of the lab rats in this 'experiment'.

After asking him if he would be available to help me with my project he said "sometimes," and asked what kind of project I was working on? When I told him about the Pietenpol project, and that it came with a turbo-charged Corvair engine, he immediately said, "I am not a fan of automotive engines in aircraft, those Pientenpol builders seem to like them, but then again they are flying over farms and fields, and up here we don't have any of those, so if your engine quits..My advice to you is to get a 0-200 or an 85 horse engine for $15-16,000 and forget about the Corvair. My question is how many of you using Corvair engines have encountered mechanical or carb ice problems while flying with this type of engine, and been forced to land as a result of either?

Rob, Not my text, I just cut and pasted this from a website: ------As the aircraft carburetor vaporizes fuel, it cools the intake air by evaporation. The carburetor venturi also cools the air by adiabatically expanding the intake air, known as the Joule-Thomson Effect. If the air temperature drops below the dew point, moisture in the air condenses into water droplets. Thus, water can be present in the carburetor even when flying in clear skies. Ice forms near the aircraft carburetor butterfly when water droplets strike parts of the carburetor (typically the butterfly and venturi) that are freezing. Freezing is determined by: the outside air temperature, the temperature drop, and heat absorption from the engine. With the throttle partly closed, such as in a low power descent, you may have a 10" Hg or more pressure drop across the throttle butterfly. The more gasoline the carburetor evaporates, the colder the carburetor. As your engine idles at the end of the runway, little fuel is evaporating and the carburetor's temperature may be above freezing. Adding takeoff power increases the rate of fuel evaporation. Now the carburetor may be cold enough to form carburetor ice. Your carburetor can get pretty cold. The heat loss from evaporation of gasoline at the stoichiometric ratio creates a theoretical temperature drop of 40 degrees F. The adiabatic expansion of gas across the carburetor's venturi also lowers the temperature. Thus, you could drop the carburetor temperature to freezing and form carburetor ice at an ambient temperature of 72 degrees or higher. Stoichiometric is the leanest possible mixture. At richer mixtures the ambient temperature at which carburetor ice forms is even higher - Lycoming publishes a temperature range of twenty to 90 degrees F. for carburetor ice. Adding alcohol to gasoline dramatically increases the ambient temperature where ice forms. Evaporating methyl alcohol creates a temperature drop of 300 degrees F. As a result, carburetor ice occurs over a wide range of temperatures. Your Continental aircraft engine forms carburetor ice at a higher outside air temperature than your Lycoming engine since the carburetor on a Continental engine absorbs less engine heat. Continental mounts the carburetor to the intake pipes away from engine heat. Lycoming mounts the carburetor to the oil pan where it absorbs heat from the engine oil. One side effect of forming carburetor ice at a higher air temperature is that the warm air holds more moisture than cold air; therefore, you have a potential for greater carburetor icing with Continental engines than with Lycoming engines ------ The Corvair WW setup is very similar to a Continental engine and carb heat must be applied! During test running of my Corvair on a test stand I could measure (and see and feel ) the cooling effect right behind the carburetor. It gets cold ! ...very cold at part throttle, the high humidity will cause the outside of the intake manifold to get wet (water droplets) image what happens on the inside. I copied the setup that Mark Langford uses on his Corvair see >>http://home.hiwaay.net/~langford/corvair/airbox/ Not his air box but only his heat pick up around the exhaust manifold. My exhaust manifold is however not stainless steel (stainless steel is poor conductor of heat) I used plain carbon steel and painted it black (maximum heat rejection). This works very well, the recommended 90 F temperature rise is easily achieved. The hot air is robbing a lot of HP, In flight I can feel the extra few RPM/HP kick-in when I remove Carb heat. Carb heat is not a problem in summer months in the Houston Texas area, as temperatures are 90 - 100 degree but rest of the year the temperatures are varying between 60 to 80 F and humidity is high year round. I fly with carb heat on constantly, only during take off and taxing on the ground I use cold filtered air. Right before take off, during the run up I apply carb heat for about 1 minute with engine at 2500 RPM. Hans ________________________________________________________________________________

Hello, I'm trying to reach Pietenpol folks to let them know about a wings & wheels fly-in event on June 11th at Lansing airport in Lansing, Illinois. I am with the (Ford) Model A Restorer's Club and we are working in conjunction with EAA Chapter 260 out of Lansing. We are, in part, celebrating the 80th anniversary of the historic Ford hangar at the airport, which was built by Henry Ford for his Tri-Motors. There is a good chance that we will have a Ford Tri-Motor at the event. There will also be other antique, modern, and experimental aircraft, as well as a large number of Ford Model A's (and some T's). There will be a pancake breakfast and lunch as well. It would be great to have at least one Pietenpol because of the obvious connection. Please visit www.jolietmarc.org (go to "Upcoming Events") for the full details, or feel free to contact me. Also, feel free to tell anyone else who may be interested (general public welcome).

I'm guessing I'll cruise around at about 700-1200' AGL and maybe 80mph or so looking for illegals for 2 or 3 hours at a time (yes I call them illegals!) We'll also be trying out one of my new aerial video helicopters to try and spot illegals. I had a major setback in that business in February but some things have happened and we're going strong with a couple new helicopters that aren't as failure prone. so get your Piets (or whatever you can get your hand on) and help the Minuteman Project by volunteering some time and gas money to help secure our borders!!

A few hours in to the test phase I had a engine out and had to make a off field landing, which was no problem as I had enough altitude to find a good field. No damage to the Airplane and a few experiences wiser. The engine out was caused by a fuel starvation problem. I used a 11 gallon wing tank and a 2 gallon header tank, the 2 gallon tank was empty when I landed. ( could hear the fuel flowing back in when I was on the ground) The original system had a ventilation line on the 2 gallon header tank to avoid air in this tank. However in flight this vent would create a pressure on the header tank that stop all fuel from the main tank. The vent cap of the main tank is also in a low pressure area on the wing, which contributed to the problem. I made some fix with a check valve on the header tank vent line ( air allowed out but not in) and re-arranged the vent line to avoid excess pressure. I flew another 4-5 hours this way but was never comfortable with it. A 2 gallon header tank gives you about 25 minutes of airtime at which time you get the urge to land. I finally removed the 2 gallon header tank and replaced it with Piper J3 tank in the nose (12.5 Gallons) it shifted my CG forward which I compensated with changing my exhaust system ( changed the cast iron manifolds for a much lighter header system) Been flying with that setup for more than 20 hours now and have had no problems. My Corvair is a '65 , 110HP Corvair conversion as per William Wynne manual. It is a very smooth and powerful engine, I would rate its reliability as very high, very close to a Continental. If it had dual spark plugs it would be an equal. Still fly with a non nitrated Crankshaft too, although I have a spare one that is being nitrated. If I had a O-200, C90/85 I would have used it,only because you do not have to deal with a 40 Test phase (25 hours if you have a aircraft engine) Of course there is money issue as well, total expense on my Corvair was 6,000- US with all moving parts to new specs, I did not cut any corners on rebuilding the engine. (the crank in hindsight being the exception) Furthermore I believe two more Pietenpols had to make a forced landing last year, both Continental powered, go figure.. It is very rarely the engine that causes a problem it is most likely the systems around it that fail. Hans ________________________________________________________________________________

Hey all, I was spending some time last night drafting out my fuse sides and ran into an area that needs some clarification. The dimensions for the pilots seat back (22" long) and the seat front (6" high) end up making a seat that just doesn't "look" right. The rear seat support ends up very close to the bottom of the fuse and the angle between the seat bottom and seat back is about 84 Deg. Does this sound about right? or what have others done in this area? It would be easy to raise the rear support an inch and add a wedge to the seat back to give the seat a more "normal" look... Looks like it is time to build a mock-up and sit it in front of the TV for a while to see what is comfortable. Dan L.

I can see a lot of reasons not to use carb heat all the time. When you heat the air going in, you reduce the density of the air and thus the horsepower. At that point you need a higher power setting to produce the same amount of HP burning more fuel in the process. Worse than that you will lose more than just a few RPM's if left on at takeoff. That power just might be what gets you over the tree tops. Most installations when you pull the carb heat, you also by pass the air filter. Lots of people think that carb heat helps the engine warm up faster so they taxi out with carb heat on with no idea that the dirt the landing gear is kicking up is being sucked into the engine without any filtration at all. There is can work like sandpaper on expensive engine parts. Everyone should have a solid idea of what carb ice looks like. Some airplanes and engines are more prone to it. Someone asked about reasons for engine failures on a few posts ago. The last order I heard for the most common reasons for engine failure are 1. No gas on the airplane. 2. Contaminated gas on the airplane (water trash ect) 3 Gas on the airplane, but the fuel selector on an empty tank. 4. Carb Icing. There is a lot there we can do something about isnt it. ----- Original Message ----- From: <harvey.rule(at)bell.ca> Sent: Thursday, May 04, 2006 3:06 PM Subject: RE: Pietenpol-List: Corvair Flyers - long reply > > Everybody I know of who flys up here only uses carb heat on the down > wind,base and final portion of the landing.Unless they are on a long trip, > now and then at intervals ,they will turn on carb heat to make sure the > carb is clear.I know of no one who flys with carb heat on all the time as > this letter would suggest???????????????? > > -----Original Message----- > From: owner-pietenpol-list-server(at)matronics.com > [mailto:owner-pietenpol-list-server(at)matronics.com] On Behalf Of Hans > Vander Voort > Sent: May 4, 2006 12:25 PM > To: pietenpol-list(at)matronics.com > Subject: RE: Pietenpol-List: Corvair Flyers - long reply > > > > Rob, > > Not my text, I just cut and pasted this from a website: > > ------As the aircraft carburetor vaporizes fuel, it cools the intake air > by > evaporation.

There is one thing I'm ever so grateful to Corky for installing in 41CC- an access cover to allow access into the tailcone from underneath. Laying on a typical automotive creeper, with this cover removed I have full, complete, and ready access to the elevator bellcrank assembly and all the cables running aft of the pilot's seat. It even turns out to be the exactly correct distance for my bifocals to focus on the assembly without me having to move my head up and down to focus to adjust the turnbuckles and safety them ;o) I really don't see how you can do without this, other than fully assembling the bellcrank assembly and attaching control cables to it prior to covering the aft fuselage. The one Corky made for 41CC is just a flat piece of aluminum about 16" square, attached to the underside framing members with PK screws. Pictures on request. Gee, it never occurred to me that if this access cover hadn't been installed, getting back into the tailcone to re-rig the elevator control cables could leave me feeling like the morning after my wedding night like it did Harvey.

The dimensions for the pilots seat back (22" long) and the seat front (6" high) end up making a seat that just doesn't "look" right. The rear seat support ends up very close to the bottom of the fuse and the angle between the seat bottom and seat back is about 84 Deg. Does this sound about right? or what have others done in this area? It would be easy to raise the rear support an inch and add a wedge to the seat back to give the seat a more "normal" look...

Noise? What Noise? I had the engine shut off. But I have many times thermalled with eagles with the engine on. I am using an intake silencer, dual muffler, and a three bladed AERO prop with flared tips to cut down noise. Thermalling with two people I set the throttle to a flat cruise, hit a thermal and turn to stay in it. Once I have 5,000 feet and I am flying away from a ridge or over the face of a peak, I shut down and glide back to PABV.

I intend to make some minor changes... nothing radical. I'm a pretty big boy. I'm just looking for a tad more room in the rear seat mainly...but I wont go into that at this time. I did however, Find the"Interesting trim" thread...well, interesting. I would like to throw an idea on the table for everyone's consideration and if you wish, comment. What would you think of dual trim tabs, one on each elevator half ? I'm refering to a very simple single "bowden cable" type arangement with seperate levers in the cockpit to control each trim tab. I'm wondering if in addition to longitudinal trim, a controlled "rolling moment" may be induced by the seperate trim tabs that might pickup a heavy wing or perhaps a out of rig rudder? Could the tab positions be noted and adjustments to the rigging (All axis's) be made to have a hands off airplane in cruise? Once the aircraft is rigged to its own "groove" would the tabs be just that much more efficient? Could the airplane be trimmed to fly hands off in all flight modes and airspeeds. I like a airplane that flies hands off once you have it setup. The airplanes seem to like it too :-) The less I *bother* them...the better they fly. Anyway...what do you think?

Dave Others have probably made the changes you are thinking about. Get into the archive section of the list and type in some key words like (Cockpit door) (widen fuselage) (fuselage step) or whatever. It can give you a lot of answers before you know what all the questions are. I suspect that a bit of the discussion on trim recently was bouncing ideas, rather lightly, on trim. You might want trim if you are running a nose tank. However, I use a 13 gal wing tank with 4 gal reserve in the nose. I have absolutly no need for a trim tab. The Piet flys almost hands off at normal cruise. To climb, go to 2100 with the A-65. to cruise level hold 2000-2050. To decend reduce to 1900. It is a beautiful flying machine. Pure simplicity.

Since, with a passenger in the front, there is no forward visibility,,,,, when something on the right startled me. Thought it was a plane in that first milisecond. It was a goose! Startled the crap out of me. He was flying the same heading and altitude as me, but just 30 feet to my right. That would have been something to have run up his tail. Since that wouldn't be a forceful strike, more like a Deli slicer, would it have taken out my wooden Sensenich prop??

Kurt, I went to a local ships chandler and bought some stainless steel bow shackles. They were much cheaper and of better strength. Check out this UK site for examples, http://www.boatsnbits.co.uk/acatalog/Online_Catalogue_Shackles_78.html I drilled out the threaded part, closed up the gap a bit and used standard clevis pins.

I once heard a Grumman Goose pilot describe its glide characteristics as: "If you lose both engines in the Goose, throw a brick out of the cockpit window to see where you will land. After landing, run quickly from the airplane to avoid being hit by the brick." You and Galileo are right, if there is no air. In the presence of aerodynamic drag, a tumbling brick will fall considerably slower than a bowling ball. Now if you can manage to stabilize the brick to fall narrow end first, it might actually go faster than the bowling ball. Neither will fall as fast as a Pietenpol seems to with power off.

All Goose, brick and bowling balls aside. When I had my engine out I was at 2000 Ft AGL. I landed easily on a field 2000 ft away while making a 180 in to the wind. If no turns where made and wind was 0, I would expect a distance of 4000 ft. Not knowing the optimal glide speed, I kept 50 MPH. My guess would be a engine out glide ratio of around 1: 2 or 1:3. More importantly the Piet is slow, even with the nose pointed down it will take some time to get there. With the throttle at Idle the glide ratio depends on what idle RPM your running and the pitch of your prop. A low pitch Prop and a engine at low idle (600) creates more drag than with the Prop at standstill.

I would agree with Hans. In my own forced landing, my engine was still running and putting out about 1300 RPM, which extended the glide, but was not enough to keep it in the air. I was at 1200' AGL, and was coming down at 400 fpm. There was little wind and I made it about 2-1/2 miles before setting it down on a road. I also used 50 mph as "Best Glide Speed". My guess is that with the engine out, the descent rate would be somwhere around 1,000 fpm, which when combined with a forward speed of 4400 fpm (50 mph), would give a glide ratio of 4.4:1. Not very impressive, and on the order of the glide ratio of the Space Shuttle. To get an idea of what that kind of glide ratio feels like, consider this: In order to simulate the space shuttle glide, NASA uses a Gulfstream IV with the thrust reversers ON to give a similar glide path.

After having fallen silent 541 days ago, the mighty A65-8 engine on the nose of NX41CC has once again roared to life! Pictures (none of the engine running though) at http://www.flysquirrel.net/piets/engine/engine.html . After reinstalling the overhauled tailwheel unit and the new harness for the left mag, I rechecked prop tracking and prop bolt torque and went over everything one more time. I had added yellow tips to the prop for increased visibility of the prop while running, and I put the fire extinguisher at the ready, tied the tail and chocked the mains, temporarily installed the fuel tank and put in four gallons of gas. I pulled it through a dozen or so blades with the mags off, then turned on the fuel and mags and gave it a go. The engine putt-putted after a few pulls and then it flooded so I killed the mags and pulled the prop through backwards, cut off the fuel, and tried it again... this time it ran but a bit rough and obviously rich. The very best news is that the oil pressure only took a few seconds to come up. I was worried about it being able to prime and pump after sitting so long, but the pressure came right up to 30-35 psi and did well. I wasn't able to test the carb heat because after a mag check, I quickly found out why the engine was running rich and rough... the right mag (old "lunch box") was completely dead. I have miswired the P-lead wire from the right mag to the ignition switch, so I need to correct that. I ran the engine for about five minutes and the amazing thing is that it started so easily and ran so well on only one mag. Should be a piece of cake with both mags working, even without an impulse coupling to help starting. For now, I'm immensely proud and happy to hear the engine start and run, and I got to work the throttle and get my hair all blasted by propwash. It was a thrill. I'm down to short rows now before she'll be ready to put the wings back on and try some flying!

Walt, In 1985, at the ripe old age of 13, I saw the Pavliga Air Camper (Sky Gypsy) in Sport Aviation. I remember telling my Dad I wanted to build one of those and that it was going to have the same kind of wheels. It took quite a few years before I actually started building but when I did and when I got to the wheels I copied Frank's. The covering is really simple. Getting the tires on without messing it up isn't. Just cut a big circle of fabric a few inches bigger in diameter than the rim with a hole in the center. Make a big 'washer' out of aluminum that will fit over the hub and cover up the spoke ends. I cut little pie shaped cuts and folded and glued those around to the back side of the washer. Position the fabric over the hub and start glueing the edges around the inside of the rim. Once both sides are done then glue a tape all the way around the rim to tie the two sides together. This probably doesn't really need to be done but can't hurt. Finish like any other fabric surface. I put an inspection ring on the inside of both wheels. I leave it uncovered and placed it near the air valve. With your tires already on the rim, you could probably just let the air out and clamp the tire flat to get to the inside edge of the rim. Wouldn't have to deal with getting the tire on without damaging the finish. Tire change time though you'll have to deal with it. Mask the edges and use lots of soap and a little cussing. Hope you try it. Keeps from having to clean the spokes and you'll probably pick up 1 to 2 mph!

Subject: Pietenpol Glide Performance
Now steady on chaps, all this talk about bowling balls and bricks applies in my opinion only to the glide angle that an idling Pietenpol would achieve. In my experience (Continental A65 / Sensenich 72-42) the sink rate is not that bad, and certainly such that one can climb in reasonable lift from thermals, ridge and wave. You can't really then go anywhere without opening the throttle because of the poor glide angle, but you can certainly get that "Something for nothing" feeling that inspires a lot of glider pilots, and there is also a good chance of coming across soaring birds in most locations, which is indeed a fine thing.

Subject: Glide Performance
Mike Hayes is right that you can get some thermal action in a Piet and on many, many occasions I have had to throttle back and push the stick forward to stop the ridiculous rate of climb when I hit thermals.........but with power at idle, you have drag city written all over a Pietenpol and the only thing that will glide worse is a biplane Jenny or old fashioned ultralight with cable braces and tubing everywhere. When the engine quits in a Pietenpol your circle of choices to land is very tight....and it drifts with the wind.

Hiya Ben, Thanks for the welcome. I'm NW of Jacksonville near a little two horse town called Callahan. You're right. Most all airplanes I've seen plans for used 1/4" X 1/4" capstrip. Even with spruce 1/4" X 1/2" seems heavy duty and I intend to build mine with fir. Spars will be laminated fir as well and may be 3/4" thick with 1/8" ply plate doublers where needed to maintain proper diminsion associated structure. Still havnt decided for sure yet. I may extend the wings a couple of feet which will reduce wing loading a little and help on a hot humid day down here. Rib nose blocks will be 1/4" marine fir or Okume. Whatever I can find locally. As I mentioned .020 aluminum L/E and trailing edge will be aluminum as well. I just have a good bit of this stuff on hand already and figured I would use it. I'm not really a "purist" but safety is first and foremost and really like this forum. Seems like a great bunch of people that really know there "Piet's" Thanks for any comments or info.

Dave, My Piet is not flying yet, so consider my advise accordingly. I would not reduce the size of the rib capstrip unless I had an aero engineer run the numbers first. Yes the 1/2X1/4 is larger than most wood truss type ribs, but the Piet and to some extent the GN1 wings are designed differently than other wood wings. I think the Piet rib is used to carry more of the loads than some other planes. Just my 2 cents.

Dave, Welcome aboard; we can always use some additions to the Florida Piet 'herd'. I am on Tavares,FL; about 35 miles NW of Orlando and I built my bird of Doug Fir for all the structural stuff. Also used 3/4" laminated spars. I concurr with the theory that Bernard built 'hell for stout'. I made my longerons 15/16" vs 1" and if I were to do it over I believe I would go with 7/8". I don't think you are too far out to think about using 1/4" square cap strips. After all thats what Pitts and a lot of other planes have used. I'd go to 3/8" caps no problem. You could make sample test ribs, a 1/4" and a plans 1/2 " and do a static destructive load test just to get an idea of what the feasibility would be. I used to fly with the Navy Flying Club at NAS Jax and I used to take students over to the grass strip at Callahan frequently.. At Thomasville a few years back there was an interesting Piet from Callahan; it had an aluminum covered turtle deck.

Using 1/4 X 1/4 instead of 1/4 X 1/2 capstrips will save a little over 2 1/2 pounds if using spruce and a little over 3 pounds if using douglas fir. I know weight savings is important but, personally, I would look elsewhere for weight savings. Additionally, some info says to use 1/4 X 1/4 if your hp is 65 or less. Other than the slipstream, I don't see a connection between hp and capstrip size.

Before today I have never actually seen a completed Pietenpol. I emailed Walt Evans to see if I could take a look at his plane since I was driving out to New York City and he's in New Jersey. Being the nice guy that he is he extended an offer to meet me at his hangar. It was drizzly and WINDY and he came out and showed me around his plane. Can't say enough about what a nice job he's done. I also can't say what seeing the finished product means to somebody who just has a bundle of wood, T-88, a rib jig and a couple of ribs and an easle with plans resting on it. Wow! After talking for quite some time I thought we were wrapping up and he asked if I was interested in a ride. The wind had died down and conditions had improved. I didn't want to impose but at the same time I didn't want to pass up an opportunity like this. So I took him up on the offer. Getting into the passenger place helped me brush up on long lost jungle gym skills and then, there I was, looking at his passenger panel. I couldn't believe it was happening. He fired up the Continental, taxi'd out, and before I could say Holy $#*% we were in the air and climbing! Right then and there, it hit me. This is what it's all about. Definitely an experience that I'll never forget and a catalyst for my project. I knew it would be fun, I just didn't know how much. Like I told him, I can't remember how many times I said "Wow!" during the drive home. Thanks Walt!!!!! Nose to the grindstone, shoulder to the wheel.

William Wynne has posted an update on his website, at http://www.flycorvair.com/hangar.html . The Zenith aircraft factory will be hosting a "Corvair Day" on May 20 in Mexico, Missouri. Not a "Corvair College" workshop, but an open house and meet/greet. William will inspect parts if you bring them. Looks like his next project is to develop a firewall forward package design for the CH701.

I agree! The Internet has only been around for 14 years now. Postal letters have been around for hundreds of years. Although many folks tout the so-called advantages of email and websites, they simply don't have the track record that serious communicators demand. In fact, I knew a guy who got the Internet and joined an email list and within a month, he started to get messages he didn't like. He sold his computer, and has been happily using the US Postal Service ever since. You're free to do what you will, but I don't want to be a guinea pig in some techno-geek's big worldwide social experiment. Seriously, this discussion has been annoying me a bit to watch, though it's nothing new. I do appreciate Jim publicly clarifying that he wasn't trying to malign William, which is more than usually happens. But some perspective is in order here. Obviously, nobody's forcing anyone to use an engine they aren't comfortable with. I'm personally sold on the Corvair, as I've come to know William and the Hangar gang well enough that I have faith that they are honest and straightforward in their dealings and that they are right when they say that I am capable, with their help, of building a satisfactory Corvair-based aircraft engine for my personal requirements. I have heard them tell people both what this motor both can, and cannot, do, and if anything I've seen them consistently UNDER-sell the capabilities of the Corvair rather than OVER-state it to try to sell products. In my experience, they've never, ever encouraged folks to do anything blindly just "because they said so"... they have always been willing and able to back up their recommendations with sound reasoning. Most importantly, this is most often based on significant amounts of actual flight experience, not theoretical calculations or single tests as some other folks will use to "prove" their products. If they only have one or two data points, or none, they will make sure you know that fact. They also have consistently encouraged people to learn and understand for themselves WHY they recommend to do something, or not. In my opinion, anyone who says to do something "because William says so" is missing the point somewhat, but they generally do so because they have found that he has actually earned the right to be considered an authority on the subject. This is because he really has tried most of the ideas that people have asked about, and refined the good ones so that anyone could use them. While I've heard folks criticize Corvairs before and even pull out some examples to "prove" their unworthiness, they never seem to mention the thousands of failures of Lycomings, Continentals, Pratt & Whitneys, etc. installed by "qualified" folks for comparison. 98% of the "examples" are things heard from friends of friends, etc. From the folks I've personally talked to, emailed, and read about who have actually BUILT their own Corvairs and can thus speak with some authority on the matter, it would seem that nearly everyone who has followed William's advice has ended up quite satisfied, if not extremely happy, with their Corvair installation. Most of the occasional problems I've heard of have been caused by things that William has specifically and publicly warned against doing, or happened before he even started his research on the subject. In short, folks who follow WW's advice tend to have a high chance of success with their Corvair engines. I don't "deify" William or anyone else, nor do I have any personal stake in this discussion other than I consider the Hangar Gang to be friends, who happen to be "the" experts on the engine I will build in the (hopefully near) future. However, I can honestly say that the Corvair Hangar Gang, to a person, set an excellent example of honesty, enthusiasm, helpfulness, and fun that I wish was present in everyone in aviation. This seems to have rubbed off on quite a few others (or perhaps it just attracts like-minded souls) throughout the homebuilt community, who then share their enthusiasm. I don't know why, but this seemingly attracts the occasional ire of a few folks who'd rather complain about a subject they rarely seem to have any first-hand knowledge of. I'm no engine expert myself, but if you ask me, even if you don't choose to fly a Corvair yourself, you should have a healthy dose of respect and appreciation for the many positive contributions that the Corvair folks have made towards furthering recreational aviation. We need a lot more folks like them in the aviation world. BTW, most homebuilt companies now require a signed legal release before selling plans or products. This is simply a factor of today's out of control legal system, NOT a lack of faith in their own products. It isn't the plans purchaser they are worried about, but their survivors's lawyers. It doesn't matter whether the accident really had anything to do with the manufacturer or not. -Mike Mike Whaley merlin@ov-10bronco.net Webmaster, OV-10 Bronco Association http://www.ov-10bronco.net/ > > Unfortunately, that's a rather fallacious argument.

I am right around 900lbs in this condition and am just wondering what you guys would expect for climb. Thanks, Don Emch I haven't got a ROC instrument, so I just put the ASI on about 50 mph,and live with whatever the rate of climb is. I am at 960 lbs, solo, with 20 gal full fuel, field elevation is 1360' at Cook Field, turning close to 2000 rpm. I suspect it is somewhere around 200 FPM, and is never above 300 FPM. My ROC has improved a little bit, since I reworked my prop, and now I can now get full rated rpm (2300 rpm), in level flight, full throttle. If I wax the prop and the leading edge of the wing, in my mind, I get better performance, and the bugs wipe off easier !! Chuck G. NX770CG going out to 'whack some bugs' this evening !!

Subject: BUILD TIME
Does anyone have there build times broken down by section that they would like to share? I'm curious about how long it takes for the fuselage, wing, empennage, gear, covering, etc. Thanks Boyce ________________________________________________________________________________

Subject: Re: BUILD TIME
Boyce: I find build times are kind of irreverent. Building my center section seemed to go on and on for ever, and ever. When I framed up a wing it went so fast that I thought I could have both done in a month, Then I got into the small details which slowed things WAY down. It took about a month to build that one wing, and it was spread out over two summers. My whole project was to be a 2 year thing, I'm into year 8! Bottom line..don't sweat time, just get started and keep plugging away. I'm glad I didn't try to build to a time schedule. I would be building an imaginary Piet in a padded cell some whare.

Thank you guys very much for all the rate of climb info that you shared. I timed (no vsi) my climbouts the other night and got to wondering what others were seeing. I am spinning a Hegy 72 X 44 prop. I seemed to be timing about 350 fpm. I notice a real difference between 45 degrees and 80 degrees. I've noticed a difference in everything else I've flown but the Piet seems to be fairly sensitive to temps. It was a little breezy the other night and the Piet seems to be sensitve to that too. I'm sure it's just me not really used to flying something so light. Just a ball of fun to fly though!!! :D Don Emch Read this topic online here: http://forums.matronics.com/viewtopic.php?p=34327#34327 ________________________________________________________________________________

Pieters, Does anyone have any experience with croming 65 cont cylinders. Mine are .015 over and pretty much to the limits and I wonder if new ones are aviable, if crome is the best way to go and which type is the best and what are the cost. Also is anyone flying around with the cg at 30 percent and how does it fly. I could lose some weight but you know how that goes.

Ken, Re CG, as you burn off fuel the Cg will be moving back with you in the plane. Even a traditional NACA wing does not allow over 32% aft cg. The Piete wing as designed doesn't allow that far aft without mucho problems with needed lift from the tail feathers, and loss of control. highly recommend a) cut back on the big Mac's (my problem), b) add some lead to the engine compartment if your gross weight is ok with added lead. Aft CG dangerous place to be. I designed my Piete with an 0-235 extended forward and battery forward of empty cg and still need to be sure not to fly with less than 5 gal of fuel so not to go beyond 32% of chord. My Piete has Aeronca wings, more forgiving than original Piete Gordon ----- Original Message ----- From: Wizzard187(at)aol.com To: pietenpol-list(at)matronics.com Sent: Friday, May 12, 2006 5:31 PM Subject: Re: Pietenpol-List: Re: Cylinders and CG Pieters, Does anyone have any experience with croming 65 cont cylinders.

Chroming was a way to go for a while, but it seemed to have some problems. I would check with Superior Aircraft as they have cylinders for nearly every engine that was ever built. They would probably overhaul yours of have an exchange set waiting to ship to you. The worst engine problem I ever experienced was due to a broken rocker box in a Cont 0 200 (Guys trust me they don't run well on 2 cylinders, but it ran) and it was replaced with a Superior cylinder. That section had been greatly beefed up and was much stronger than what came from the factory. ----- Original Message ----- From: Wizzard187(at)aol.com To: pietenpol-list(at)matronics.com Sent: Friday, May 12, 2006 9:31 PM Subject: Re: Pietenpol-List: Re: Cylinders and CG Pieters, Does anyone have any experience with croming 65 cont cylinders.

When I built my A65, my cylinders were worn to the limits. I looked into having them chromed and rebuilt. Cost was $550 per cylinder. Then I looked at Superior's Millenium cylinders which were $800 per cylinder, but you got new pistons, new rings, new valves, new valve springs, new valve seats, new rocker shafts and new piston pins. With the rebuild you have the questionable durability of the chrome, plus everything is still 60+ years old. I bought the Millemium cylinders. An added benefit was the increased accuracy of their casting process for the pistons. I weighed all reciprocating components to get the engine mass balanced as well as possible. All four of the new pistons were within 1 gram of each other. The original pistons varied by as much as 10 grams. The engine runs extremely smoothly.
