can someone help me, I want to be sure about the wing's.I bought the 50 cc ultimate it look's like a great plane but the instructions are very non discriptive on anything to do with the assembly(a few pictures and a few icons to show where to glue). I don't want to make a mistake on the assembly so i am not sure if the top wing's are to be glued together seeing that the bottom wing has a tube thier is no instruction on that at all. Could someone that is more intelligent than I please get back with me on this. Thank you James
