How many times have you wrestled with those plastic wing bolts that twist and distort in hot weather ? well here is a proven method that does away with the silly nut that nearly always gives problems,instead of using the nut make a quarter of an inch wing attachment platform,either key this into the fuselage or give support with balsa V-section,place the wing into position and mark with a sharp point where the bolt goes,remove the wing and drill and tap to take the plastic bolt,place a piece of alloy tube between the wing and fuselage to act as a stop,just cyno this to the ply plate,this also serves as a guide for the wing bolt which has its thread smeared with domestic soap ( old door fitters trick ) to glide into position.
This idea will also give much better shearability in the event of a crash,to remove the broken bolt just heat up a screwdriver in a flame,plunge into the plastic bolt and remove,easy does it !
