If you do not put in right th. in it. your bipe. what you will get it a trim that is not at 0. You land your plane and walk up to it you will see you ailerons one up and one down just a touch to fly Laval. Right th will take that out. with it being a tail dragger you will need just a little more right rudder to keep it striate on the run way. With the down th the plane will tell you if it needs it if it blooms.

I know a lot of people that will put all at 0 and set up mixers to do the rest. I guess what I am saying is it is all in what you want to do with the plane.
