You have until the video uploads to make your predictions.
My guess is no, I've messed around with designing small flat wing foamies( I realize this may not relate to a balsa model with air foiled surfaces, but it's just my guess) and I found that extending the top of the rudder and therefore the height of the balance tab dosn't help wing rock. But if you extend the height of the vertical stab and keep or reduce the size of the balance tab it does seem to help wing rock. I like the experimentation on this plane, it's kind of brought this thread back to life although not quite as entertaining.
