What are people using to fasten the wing

or - are there any recommended fastners that are less likely to crack the
fibreglass tips over time? Thanks for your comments.
Nicholas, we used #10 stainless steel flat head screws on
ours. #8's are probably OK, but be sure to use the number specified; don't
short the plans on this. The #10's give a slight amount more
fastener surface area, but we used them primarily because they are easier to get
in and out without damage. Also note that there are more screws on the bottom
than on the top. The most important step is reinforcing the end of
the basic wing skins per the manual. I seem to recall that this is a
10 bid build up and it makes the interface pretty stiff and strong.
Have not seen one of these with
cracks...
Good
luck!
