Re Wing flexing......I remember an episode of wings once that included the Galaxy 5A......you should see THAT one. If I remember right, there is a system to 'dampen' the flexing....when they turned it off, it looked like the d@mn thing was flapping it's wings like a bird. Perhaps Galaxy flyer could confirm this....? Actually, the only thing that bothers me about this problem is that the aircraft are basically brand new, and this is showing up already. I understand with a new design that there are always 'teething pains'.....but this situation is rather surprising. It will be interesting to see what comes next.....
