Subject: Pietenpol-List: one man's method of rudder stopsTwo blocks of poplar with T-88 glued as shown in front of the rudder bar to prevent the rudder from hitting either elevator.My FAA inspector wanted to see control stops (Bingelis warns of this in his books plus it just makes good sense)on all of my controls.Mike C.________________________________________________________________________________

thanks guys, I will glue some stops on for the rudder bar.- Gardiner

et>Jorge,Mount the empennage.- Test for travel.- See how and where the rudder might hit the elevators.- Measure carefully.- Back up a little for greater assurance, and to account for empennage flexing in flight.- Set the stops.- (I think that is what others are saying, and it makes sense to me.)- As I recall, Oscar told me a while back he thought he had 2.5 inches of travel plus or minus (5 inches total swing) on the rudder pedals or rudder bar.)- See what you get.- Tim in central TXno authority on this-----Original Message-----

built one of what? a pietenpol?? local guy here almost killed himself in one too, but he forgot to turn the fuelon when he realized his mistake he found he couldn't reach the valve. But thatwas 100% pilot error so I'm not sure what you are saying here. Boeing once lost747. sooo. . .Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

In the Air Force, their way of having control stops is to have stops on both the pilot's control and on the surface itself. I think that the idea is that you'd bottom out the surface and have about a paper's thickness (using a piece of paper as a feeler gauge, most paper is about .003 inches thick) at the control stop.There's a reason to have stops at both locations: the stops at the surface prevent, if flutter occurs, motion of the stop past the limits. And the stops at the controls prevent a very strong pilot from breaking the control system. However, while that might be considered desireable practice, all the FAA asks of certified small planes is that they have stops at the surface. So for the rudder, the stops would be at the rudder. Stops on the rudder bar are optional.I remember that some of the intermediate control linkages also often had stops. And that some, fancier or more critical than the others, had rigging holes to facilitate adjustment.You'd insert a rigging pin in the control, for example, and adjust the wires or pushrods to get the next linkage lined up. Then a rigging pin at that location, and move on to the next linkage. Adjust that, put the pin in, and continue on. Eventually you'd have the entire system pinned and everything aligned. Safety the connections and remove the pins and you're done.Overkill for a Piet, but very easy for the mechanic.David Paule ________________________________________________________________________________Date: Sun, 6 Dec 2009 11:53:00 -0800 (PST)
