Microraptor gui used a biplane wing arrangement. (Hopefully this isn't a registration-required link.)

Presumably, Microraptor controller had jet engines and Microraptor model was a helicopter. (This has been your bad programming joke for the day.)

Also, I mistyped both of those "Microraptor"s as "Micromaster." I think I've been spending too much time on the TF wiki.
