Michael,Just looking at the photos of your rudder bar modifications, and I'm wonderingabout those pedals. First off, they don't look very robust. I'd be worried aboutbending them out of shape with the application of a little extra force -the kind of force that gets applied when things get a little hairy (e.g. gustycrosswinds.)Additionally, you say that the driving force behind your modifications was to avoidapplying unwanted forces on the rudder bar - yet the pedals as you have builtthem will now load the rudder bar eccentrically. There will be a momentimparted on the pivot bolt in the center of the rudder bar because the forcesapplied by your feet will be centered above the rudder bar. There really shouldn'tbe much worry about your toes applying downward forces on the bar, sinceyour toes won't be in contact with the bar (unless your feet are only 4" long.)Food for thought.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Rudder bar issues
