Either way I need something to start with, but I do know what you are saying. I was actually just thinking about that early today, I'm not sure how much I'm changing the foil. It's getting thicker everywhere. I don't know? Beyond my comprehension...
The other thought was to get another one and glass it. The change would be minimal that way. It could be done with some ridiculously thin glass.
I LIKE flying the Zaggy ; that thing can be flown into the
side of a brick-wall, and only the prop will need replacing;
i've don it !!
It by far the toughest design out there. I've gone through a few... I pounded one into the ground so hard the motor and speed control couldn't be found. Landed/catostophically crashed in a damp freshly tilled field. The one I'm attempting to make the plug out of pancaked into dry hard ground last fall. Popped all three carbon spars in it. lol
