    I have a Mark III, but I didn't mean to imply to disconnect the rudders. What I meant to say was to put springs in series between the rudders and the pedals that would withstand around two hundred pounds of tension. The only time they would operate would be if you pushed on both pedals and exceeded the springs limits, but before you could damage metal parts. The only time they would operate would be to save the plane from pilot error. I have not tried this, I was wondering if anyone had thought about it and tried it so I wouldn't have to. Sorry for the misunderstanding. Sincerely, Denny Baber

    Personally, I wouldn't wouldn't try that. Normally, the pedals would bend before they broke. One must try extremely hard break rudder pedals while flying or crashing. john h mkIII Plainview, TX ---- Denny Baber <baberdk@gmail.com> wrote: > I have a Mark III, but I didn't mean to imply to disconnect the rudders. > What I meant to say was to put springs in series between the rudders and > the pedals that would withstand around two hundred pounds of tension.

    My thoughts about adding springs. Cons: More weight. More stuff to break. Kind of defeats the purpose of these in the first place. May let the rudder flutter with nothing you can do expect apply more pressure and hope it works until you cramp a calf. May allow tailwheel to flutter while touching down or taking off. Provides much less feel to rudder / tailwheel operation. Pros: May prevent rudder system failure from pilot over applying pressure to pedals. I think if you really had to "Fix" the rudder pedal situation you would be better off using the additional weight the springs would have added towards thicker steel rudder pedals, brackets, or whatever you think is the weak spot. I'd rather use a system that has a great track record then invent a new system and risk my life on it. -------- Scott Olendorf Original Firestar, Rotax 447, Powerfin prop Schenectady, NY http://sites.google.com/site/kolbfirestar/ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=430196#430196
