I encountered the sticky pushrod problem myself and figured it would eat up plenty of juice fighting it...it was mostly the rudder because the control horn sits so high above the exit hole. I found that a careful series of bends in the wire to raise it to the horn level worked and am crossing my fingers that i will not get any sloppy play. I am relatively new to this so I will let you know how it worked later
