 Re: Fishtailing Extra, Why?
A couple of years ago I was at a fly-in and a guy had a 3M C-arf Extra and it had fuel tubing on the trailing edge of the rudder. I asked why it was there and was told that the rudder was too "clean" and thin at the trailing edge and would wag. Adding the tubing took out the wag. FWIW thats what I was told.
