Re: FEGs Again --

There was a news story today about what happens when drone enthusiasts try to build more substantially sized drones without really knowing anything about designing aircraft. A bunch of Doctor Who fans built a full size polystyrene 'Tardis' held up by twelve mini helicopter type propellers, and it crashed on its maiden flight.

The article quotes the Tardis box as weighing 25 kg, and I would guess the total weight including the mini helicopter attachments might be 40 kg or more. I suspect they haven't bothered to comply with CAA regulations for drones which have a greater weight than 20 kg.
