I find it hard to believe that with all the Lightnings out there flying and only 1 issue that there is a design problem. You guys are looking at the crash photos, did you not notice that there is a servo screw missing and I could be wrong here but it looks like a plastic servo arm in the photo. Come on, you don't build a $10K airplane and not use all the parts or use cheep parts and then say it a poor design when it breaks. I sure would hate to see CARF's rep hurt if they are not at fault, I for one can't afford to buy a $20K UB. I love my Lightning and will want another one when I wear this one out.
