I also have the magnum in kit form. I don't like foam wings and most my kit wood is to heavy to use. I guess if I ever build a foam wing I would probably like it, just like the looks of the ribs. In the eighties there was quite a few magnum around, just don't seem to hear anything about them anymore. Was there ever a report or write up from one of our great flyers made on this kit? Call Tower as suggested, just got the run around, which is alright, but I did try. My fault for using parts that aren't very good. Read something once that said, if you don't want to crash don't fly. Even the great one's crash once in a while, ha ha. I'm just having fun, thanks for the info, Gary
