    Well, I'm committed now. I spent Saturday night out at the hangar cutting and grinding the offending wing fitting off. I started with a Dremel and an abrasive cut off wheel, but it proved to not be...

    Marty, just for fun the plans don't actually tell you how the wings attach! However, the outside dimension of the fuselage tabs is called out as being (conveniently) the same as the inside spacing...

    Aaron, I'm definitely going to need to stare at the fitting for a while to work up my courage to do it, but you may be right. It's a heck of a thing to pull the trigger on, that's for sure.
