I have managed to cross-thread one of the holes that my wing attaches onto and wondering if any tips of how to get the bolt in or out? Firstly not a major issue, as the wing is very firmly attached with all of the other bolts, so this is just to get is absolutely right (I like to do a proper job). The bolt is the one right at the bottom at the front of the rear wing. I have managed (!) to cross-thread the bolt so it is only half in, but now it will not bind to either come out or go in further. Any ideas on how to either get it to bind in, or how to get it out, so I can try again?
