andybuck, thanks for your indications, working on it (and rebuilding the whole wing !). Yes it's touchy to model, but at first look, I only thought about doors and wings, the easiest parts
NE, thanks a lot for your words, having them coming from someone like you sounds cool to my ears ! I'll keep going (maybe my first finished project ?). But stop kidding when comparing my work to ORB's, too much lightyears between his skills and mine
revelli, thanks !
Auto! ..klídek, thanks too, give blender another try : some years of practice, and the interface begins to be intuitive !
