By the way, you are 100% correct Volfy. At a certain point the shear web will be overkill. I hope I didn't tick anyone off. I misread what was stated above.

I have seen numerous planes fold wings at the field. If you want, go ahead and reinforce the wing a little. I believe that most kits are built strong enough and that others aren't. I wouldn't put all of my faith in the manufacturer. The small added weight will possibly payoff in the future with a non-crashed palne. Better safe than sorry?
