Praxis: Tricopters, Hexacopters & Octocopters -- the poor man's UAVs.

My thanks once more to John Robb at Global Guerrillas for bringing my attention to "hexacopters." He writes in his typical shorthand:

DIY UAVs continue to advance rapidly. Hexacopter. VERY fast mover w/lots of maneuverabilty. GPS station keeping. Significant payload. Auto retrieval. No data on endurance. Camera mount. Wiki. Lots of related videos.

Here is a more detailed description of an "Octocopter"

And here is a tri-copter with folding rotors, an important consideration for tactical packaging.
