This shouldn't have been a test with an actual pilot. One critical failure and he would have ended up like a frog going through a fan.

The main safety question is the immediate stability in case of a rotor or motor brutal failure (or double ones). The risk is that in most scenario the tricopter will brutally return itself.
Bernd Kohler
Deres, you mean instability or better crash which is unavoidable in a tri copter configuration when one of the drives fail. Putting the pilot so high makes the craft by design instable. Any craft which fly and is not auto stable is dangerous anyway. To relay on artificial stability is not a good idea to say it polite.

Sitting in the same plane as 6 high speed rotors...with nothing between you and them...ouch! That motorcycle helmet is not going to do much for your protection. Looks like the most dangerous personal vehicle ever.

The most worrying thing for me is the fact the guy on it is a total passenger. The guy with the remote is not put in the frame. It could also be terrifying if you get a GPS glitch in position hold which can happen, causing the craft to want to jump to a new location at high speed.

It seems to me that for stability and safety the pilot should be cradled in a small seat mounted inside the tripod landing skids where his weight is below the rotors and his body inside a shield of some sort.

Almost everyone keeps avoiding the fact that small diameter rotors are very inefficient even in this double blade setup. If they put the pilot below the rotors and increased their diameter this would be a much more efficient and stable machine. Maybe not quite as maneuverable but definitely safer. I really don't see any sane person wanting to do quick flips on a practical manned version.

I wouldn't sit on that tricopter without shrouded propellers. Too easy to end up as mincemeat.

Hats off to that guy, that has the balls to fly that contraption !

Congratulations. Make it safe and you will be at the cutting edge of piloted multicopter design.
