My model IV has a pretty heavy right rudder to fly straight.
I figured the left wing was a little slow so I took one turn out of the forward strut turnbuckle and added one to the rear. This "washout" adjustment did nothing.
It seemed like it was about 1/16 of an inch on the threaded portion in total adjustment which I thought would yield some change, but ... nope. Do I just need to suck it up and put in a trim tab on the rudder?
anyone got a IV that flys strait hands off?
