EMERGENCY!!! okay, i've been reading and reading and re-reading my instruction manual and staring at lots of pics about the bird cage cockpit of the L-4 aero machines and was trying to think of some way to build that into my (beginning to think) "crappy" great planes .40 piper cub kit. i really don't want to try to send the kit back to tower hobbies and get the Sig kit because i've been waiting forever for it to begin with. but do any of you guys know where i can get some sort of idea for the center wing box area on how to build the structure up for the rigidity and maybe a 2-piece wing and an idea of how to build in a working open and close door on the right side? the door is going to be the extremely tough part since one of the bulkheads is right there at the front of the cockpit where part of the door "would" be, i guess i don't REALLY need the door but it would be awesome if anyone else has an idea how to build it in. guess it really does pay off to do your research before you buy a kit and go digging around in it. darn manufacturers should all put there manual on-line somewhere for us to research before purchasing.[]
