RE: Big stick 60 wing failure
OK so this is a late post, but I love my Stik 60 and will take a closer look at the wing hold-down. I use those black nylon bolts by Great Planes in all my planes, The main reason is the hex head, but I trust these more than the white Nylon bolts. The white nylon bolts come from many manufacturers and I have had some of them fail when they should have held. They age, can absorb moisture, and are embrittled by cold. I would replace any that show signs of age or hardening. I also put a taper on the first few threads because some planes have difficulty getting the bolt aligned to get it started.I use a cordless screw driver with a socket and I torque the bolts down really snug.
