Great thread! I've only printed one plane so far, a Nucking Futs. However, I didn't take the time to make it nearly as pretty as the one in the first post of this thread.
Mine is printed with the "long wing", the upswept tips and I even printed a folding prop! I'm running it on 2S, and fly it more like a "micro hotliner" than a pylon racer. IOW, lots of climbs and power off dives with acro and fast passes. It's a blast, and flies great.

I've been toying with designing my own plane to print, but haven't had the time to sit down and figure out the internal structure tricks. If I ever do, I'm leaning towards a hybrid design, with foam flying surfaces and a printed fuselage.
