This one is for any of our many aviation engineering types...Or if you have tried to solve this same problem.
I want to bounce this off of you to find out if my aerodynamic thought processes are correct.
Problem:
My Kitfox IV has been flying very well for the last year. When I first got the AW ticket, I went up and realized right off I needed a trim-tab on the rudder as I was needing to hold some right rudder to fly straight. The trim tab is about 6" long and bent off the trailing edge of the rudder to the port side. I ended up needing to bend this tab into the airflow at Approx 45 degrees to fly without right rudder. I know this generates quite a bit of drag which I would like to get rid of.
Solution ?
My thoughts lean towards shimming the engine mount canting the engine slightly to port side. If this thinking is correct, how much would one start shimming? Or is this even a practical solution?
Thanks in advance for your thoughts.
