Climb out at 65 so the controls are responsive and you don' t mush. Fly your pattern at 65. Hold final at 65 till you're on short fina l=2C calm air=2C then let it bleed to 55 as you come over the threshold. I f there is a cross-wind=2C you are on your own! Taildragger pilot=2C do wh at you know how to do with these airplanes because this one is a stick and rudder airplane and it likes to come down when the power comes off. Over the numbers=2C if you have the nerve to look at the airspeed indicator =2C let 55 bleed on down to 45 when the lift will be all gone and you'd bet ter be able to reach out from the cockpit and touch the numbers painted on the runway because... any slower than that... you'll be squeaking the tires on the ground. And if you don't=2C get ready for a bounce! The ASI is all but useless beginning from when you're over the numbers=2C s o don't bother looking at it. You fly this airplane by feel and by sound an d by peripheral vision when you're down by the numbers. This airplane is a lways instructing and it doesn't care about you as a pilot at all. It's go ing to fly like a stick and rudder airplane no matter what you do! If you' re a good taildragger pilot=2C you and the Piet will quickly be great frien ds. If you're not a good taildragger pilot=2C you'll soon learn and THEN y ou'll be great friends! This airplane is so much fun to fly.

I see scattered thunderstorms hit or miss across Flor ida on the radar. Good to hear you've got some decent weather to taxi test in. T he day is still young:) Mike C. By the way, for all who are getting close to flight testing or might be in the next year or so this is an outstanding guide by the FAA. Just paging thru this document I found a section that describes in detail how to determine the unusable fuel for you fuel system and engine combination. There is a great section on weight and balance calculations too. http://www.faa.gov/library/manuals/aircraft/media/ac90-89a.pdf Fuel Flow and Unusable Fuel Check: This is a field test to ensure the aircraft engine will get enough fuel to run properly, even if the aircraft is in a steep climb or stall attitude. (1) First, place the aircraft's nose at an angle 5 degrees above the highest anticipated climb angle. The easiest and safest way to do this with a conventional gear aircraft is to dig a hole and place the aircraft's tail in it. For a nose gear aircraft, build a ramp to raise the nose gear to the proper angle. (2) Make sure the aircraft is tied-down and chocked. With minimum fuel in the tanks, disconnect the fuel line to carburetor. The fuel flow with a gravity flow system should be 150 percent of the fuel consumption of the engine at full throttle. With a fuel system that is pressurized, the fuel flow should be at least 125 percent. When the fuel stops flowing, the remaining fuel is the ''unusable fuel'' quantity. (3) Since the fuel consumption of most modern engines is approximately .55 pounds per brake horsepower per hour for a 100 horsepower engine, the test fuel flow should be 82.5 pounds (13.7 gallons) per hour for gravity feed, or 68.75 pounds (11.5 gallons) per hour for a pressurized system. The pounds per hour divided by 60 equals 1.4 pounds and 1.15 pounds per minute fuel rate respectively. NOTE: Formula for fuel flow rate gravity feed is .55 x engine horsepower x 1.50 pounds of fuel per hour divided by 60 to get pounds per minute, divided by 6 to get gallons per minute. For a pressurized system, substitute 1.25 for 1.50 to....... ________________________________ Message 13 ____________________________________ Time: 12:32:27 PM PST US Subject: Pietenpol-List: Re: tire pressure on motorcycle wheeled Piets From: "kevinpurtee" Jerry - My landing gear is configured differently and my plane's a little lighter, but I've used 35 psi to good effect. -------- Kevin "Axel" Purtee NX899KP Austin/San Marcos, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=374961#374961 ________________________________ Message 14 ____________________________________ Time: 12:33:43 PM PST US Subject: Re: Pietenpol-List: tire pressure on motorcycle wheeled Piets From: helspersew@aol.com I don't know about y'all, but my Piet reeeeeally likes to roll on those big wheeels.

From: Dale Mccleskey Well guys, I put N7035N down on a farm turn row in OK last saturday. Hung a wing on the corn and did the slickest "hide the airplane in the corn" trick you ever saw. Pictures attached. I've always told my wife that if I ever had to set the piet down in an emergency that I might bend the plane but wouldn't bend me. Proved the plane is a very tough little critter. Only broke the tailwheel and tailpost. It never did back up well and I guess backing into a muddy corn field is even worse. Funny part is as much as I've enjoyed the plane, I haven't flown it enough to justify the costs of housing and insuring it. June 2 was our 40th wedding anniversary, so my gift to my wife was getting rid of the plane. I determined to sell it when I got back from flight to Texas and back from Tennessee. On leg out of Davis Field, Muskogee, OK (MKO) I was climbing out and lost power. Just like I'd pulled the throttle. The FAA folks at the FSDO have convinced me it was carb ice. I've always pulled carb heat landing, but never on takeoff. Conditions were just perfect for ice. Super high humidity with unseasonable cold after thundershowers. I had to wait on the ramp for traffic to clear so had been running it a bit. Anyway, that's my story and I'm sticking to it. If anybody wants to shortcut building a GN1 variant of the Pietenpol, do I have a deal for you. I just didn't want to sell the plane and look over my shoulder with liability issues for the next 20 years. So I'm decertifying it and selling it for parts. Catch is it's a complete plane with A65, wings completely unharmed. Only damage to the fuse is the the tailwheel/tailpost, and a bent carb heat box. No prop strike and I have a brand new Cloudcars prop, only flown to Texas and part way back. I took the prop off to hang on the wall but could be talked out of it. Can't imagine anything better than building and flying the Aircamper, and you guys (including of the female type category) are great. I'm gonna keep a toe in the Piet community. Thanks guys.
