A couple of years ago someone posted a report that a milled model with weight added to make it the same as an unmilled one still flew better. Reasoning was that the milling adds drag to slow the model down. Would be interesting for you to try the same with mylar one side and then both and see if there is any difference in the way they fly.
Very neat looking model, btw.
