My micro-tricopter (motor shaft distance: 132 mm, max. dimension: 259 mm) during FPV flight. I hope everyone can guess how much fun this is :-D . Sorry for the bad AV-link, there is probably a lot of 2.4GHz noise around this pretty much populated place in Bremen, Germany.
Camera: "CCD-Killer", + f=2.1mm fisheye-lens, captured with Haupauge WinTV HVR 900H & FatShark AVout.
