Tricopters are Boss. And even better are foldabe Tricopters you can take everywhere.

I only have pictures without the motors, dont exactly know why.
But i can say this Frame is great. even with the extension due to the FPV camera mount
(which i got from here: http://www.thingiverse.com/thing:852768)
the whole craft can fold down to the size of a small bottle of water, allowing you to just put it in the sidepocket of your packpack.
Another great feature is that you can run a lot of wires on the inside of the craft, aswell that the FC can be mounted in a safe bay at the bottom, which i used for my PDB.
