@Xaldrak : Okay, so, if I get this right, we have until february 14th 12:00 (GMT -5) to complete the challenge and submit our entry, right? Also, what do you consider most important? That it's easy to fly? That it's economical? That it has a big payload (a.k.a. place for sciency stuff)? A good equilibrum between these different criterias? I'd like to know if possible. Oh and, can we send you screenshots of our progress, just to show we're not copying or ''inspiring'' ourselves from the other submissions? P.S. I see you have 666 posts until now ...
