Hey, I have my fuse mostly done and I was wondering if there's anyone that hasa plane I could look at. I've got a stack of visual questions. Thanks.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Hi Steve,I=99m basically NE of Tokyo on the Kanto plains.....one of the few flat areas in Japan!Great to hear you visited Japan. As you would have noticed, it is a very diffrent world to what we are used to!Both Piets havn=99t had much done on them for quite a while but here are some photos. (shrunk in size to save bandwidth).The fuz on wheels (with two aeroplane noise makers in the cockpits) is #1 Piet. It belongs to a Japanese bloke that I work with. #2 photo=99s are of my project (way behind #1 Piet). The rib shots show one panels worth but all of the ribs are now complete.The fin/rudder are hinged with Vi Kapler=99s hinges.Hope to get on with things again soon!Mark>I'm just curious, where in Japan are you located? >Do you have any pictures of your Piet projects?>Steve Ruse>Norman, OK ________________________________________________________________________________Date: Tue, 13 Dec 2011 10:08:22 -0600Subject: Re: Pietenpol-List: Piet builders in northern ill southern wi.

On t/o with the t/won the ground the rudder input was super sensitive, and when the tail cameup I had to add more rudder to keep it going straight. Even worse, on landingwith correct rudder input, when the t/w touched down it immediatelyveered sharplyoff. It became real squirly on roll out. With the spring tension matched tothe aerodynamic rudder as the tail comes up on t/o no change in rudder inputshould be needed.

Compression or tension spring is not the question the question is spring rate or pounds per inch.You want the rudder to move easier than the tail wheel. You want the first few degrees of rudder to actually be somewhat free and not hard coupled or you will be dancing.Sent from my iPhoneOn Dec 13, 2011, at 1:27 PM, John Kuhfahl wrote:> Brad and all,> Hmm--well I thought I had it figured out. Good point--I hear you.I am hoping I can adjust out differences between the wheel and the rudder. I put in some slack on the wheel so the rudder moves before the wheel does. Ill do some serious taxiing to see how it works. I can always go back to tension spring. How "bout both?

Subject: Re: Pietenpol-List: Piet progressDue to the effect of gyroscopic precession of the prop you will always requirea further input of rudder pressure in a tailwheel aircraft when transitioningfrom three point to two point in the take off roll. This is regardless of tailwheelrigging. Scott Knowlton. -----Original Message-----
