I thought that I had build a Lancair IVP turbine, bu= t after seeing all of the post, it must be something else.
 
  My IVP has no yaw damper, and no winglets.&nb= sp; It is very stable in yaw in all regimes of flight.  One does need = to trim the rudder with speed and power changes.  My rudder trim in on= the stick for this reason as is the aileron and elevator.
  By the way, I also found the 727 to have no y= aw problem with the dampers off except at high altitude, the operating manu= al noted this very strongly.  I only flew the 727 for 18,000 hours in = all three seats, so I am not really an expert.
