Hi,
I'm still in the covering stage of my Skybolt therefore I do not have any field experience with the wing attachement method. I have assembled the bones 3 different times in my shop and it seems to go together nicely and "feels" very solid and stable. I don't see any real problems with it, and it only takes a couple of minutes to hook up.
Now carrying 2 wings and a large fuselage out to the field in my 2 door car might be more of a problem...
