I wanted to come back and add in case someone took my last statement as recommending Nylon Bolts in the main spar instead of the metals. I WOULD NOT recomend using Nylons in the main spar. In my opinion they would shear of instantly in a high G manuver. I was just saying that the wing is rigid within the fuse anyway, so making it rigid at the trailing edge would be about the same deal. If VF thought it was good to use Nylons instead of the steel, I am sure they would have done that. Just wanted to make myself clear so VF don't get a bunch of complaints about wings shearing off due to something I may have said.
