Anheadral was the best thing i did to my Midwest 40 size stick and 60 size to improve its flying quality
Just turn the wing upside down with the servo on top
a wing with diaheadral will then become an anheadral wing
Plane rolls so much better and smoother in a tighter circle
That works only for high wing airframes

I very much like the looks of your sweet trainner with the anheadral a very clean looking aircraft

I scratch built a low wing tail dragger and built no diaheadral into the low wing
When i apply right rudder the nose goes rleft which is called adverse yaw and a bad quality
The Gruman Enginners ( full scale aircraft ) at my field in NY explained to me thst i should have built diaheadral into a low wing tail drager
Keeping the wing tips a bit higher off the runway is a good thing as well

You can view my 20 year collection of some of the very best two cycle 40 to 1.80 glo engine aircraft in my Galley to the left of this post if you like
