The "Scorpion 2" is a tricoper designed by a friend, Ricardo Fernandez and me. A GoPro can be mounted in the front directly onto the body without any extra mounts required. The tricopter can also be used for FPV Flight and capturing some great footage.

--- UPDATE ---
"Scorpion 3" is currently being designed. It's a sleeker version with Carbon Fiber landing gear mounts and where most of the electronics and wiring are inside. It's expected to be printed and tested by the second week of January.

---- IMPORTANT! ----
You can just download the CCv2-full.thing file and make it if you just want this as soon as possible. But I've also uploaded individual stl files if you'd like to print them separately and also the CATIA Part files if you're interested in making modifications. Make sure you publish them under the CC-BY-NC (Non-Commercial) License though.

Additional Parts Required:
3 x 1/2" Dia. 1' long Carbon Fiber (aluminum and wood can be used too) tube
