On a sidebar, I have a friend back here in "Minnesnowta" who flies an ancient Fairchild highwing with the upside down inline engine. When he went to recover the machine, he became aware of the fact that there was a small grommet hole in the middle of the rudder with a little screw inside. Puzzled about it for the longest time and ..... you guessed it!
