to dihedral or not to dihedral 4*60
i'm in the process of building my second 4*60.
i am making some modifications to the plane because i was not happy with some of the 4*60's flight characteristics.
first, i increased the size of the tail feathers and plan to shorten the wings by one panel on each wing.
i am also using a foam wing that will be covered in 1/16 balsa.
my question has to do with dihedral.
some of my club members have suggested removing the dihedral.
first, it's easier to build the foam wing without dihedral and aerobatic flight is much improved.
rolls are tighter and inverted flight etc is much improved.
i am not an expert flier, nor am i a beginner.
what change in performance can i expect if i make the wing straight?
thanks for your help.
