ORIGINAL: tuwood
I hadn't drilled and mounted the interwing struts yet so I moved on to that and had a major oh $*@# moment. The directions prior to wing assembly told me to drill a 1/16" hole through the number 7 rib and sure enough the hardware that comes with the kit requres a 5/32" hole. Grrrr [:@]
It's not exaclty easy clamping wood on both sides of the ply (to avoid splintering) and trying to drill sideways next to the wing... So, for those that haven't started this kit yet, the hole needs to be at least 5/32" for the blind nut to fit. I spent probably 2 hours drilling & filing the holes to get my blind nuts in but I was successful with no collateral damage.
I didn't drill mine either but I have an assortment of 12" long drill bits
