Having looked at their site (
http://www.neidhartonline.com) it looks like they will cost £9,000 for the Octi 1100mm and all you get is 10 minutes flying time?
That is not going to set the world on fire. For that sort of money there are a lot more makes out there.
Although I do like the idea of the parachute but at a maximum height of 400ft legal flight I doubt it could deploy in time to lower the landing gear and save my NEX-7 and gimbal.
There needs to be a good reason to spend that money. Is it already CAA certified, complete with CAA approved operators manual etc. Can the endurance go higher to say 30 minutes flight time etc....
