What's the back story on this thing? Very cool indeed.

Isn't that just a coax heli with some creative CF art around it?

Nope take a look at 0:53 and you can see that this is not a cannibalized heli.

Comment by Martin Seven on April 13, 2010 at 1:39pm

So a DIY coax heli then?

I have no idea, what the back story is, just found it on the tube, no doubt somebody will know. Bet the endurance is not upto much.

It's a single propeller on top with 4 flaps on the bottom. Pretty limited payload & too top heavy to land. Surprised no-one has thought of using 3 flaps by now.

I have to say I like the design the people came up with but basic design is the same as this one.

I am intrigued...have just enough stuff lying around to whip one up.....hmmmm oh the noise...

Going back to Gary's comment... No flying body, no fixed wings, I wonder what could be done to enhance the endurance on the thing?
And a total silly noob question: What would be the gain, if any, if it had some sort of solar power system built in?
Would the mechanism for the solar panel etc just be too much weight for negligible gain? I imagine so... but really have no idea.

Not enough surface area to make solar interesting.

But I too am confused about what the advantage of such a design is over a VTOL aircraft, which could save a lot of energy in forward flight. Basically this is just like a 3D foamie, without the wings. Why not just add the wings?
