maybe Kaman Aircraft can re-design the K-Max airframe body, fuselage to put the crew cabin up the top level atop of the passengers and cargo in the level below, with big clamshell doors at the front and the tricycle landing gear inverted so a front retractable passenger ramp can be added to a new fuselage design. a lot of helicopter lifting power there! ,- just a thought.

Amazing

Awesome

It's an astonishing machine, if you're used to looking at tail-rotor craft. I wonder why they aren't more widely used. I'm no engineer, but it seems a high lift to weight ratio would be useful for a lot more than cargo. One could equip a version with a roomy cabin, either for an owner who wants luxury in their vehicle--imagine Marine One with intermeshing rotors--or for seating many passengers. I could see a role for short hops in between cities or airports in some places.

You gotta say: that shit is pretty nimble. It almost looked like a drone, floating around in such a controlled grace.

So soothing to watch from far away but definitely scary to fly in one.

Due to its high lift to size ratio would this design work well if it was battery powered?

How does it turn? Also, how does it change direction?

When you mentioned the 3 d's all I could picture was a K max hovering inverted.

sincronia perfeita... dá até medo...parece que vão bater a qualquer momento!

Really elegant machine, so little parts!

Is the rotor head rigid?

Is this more dangerous to get out of than a normal helicopter? Because of the blades spinning lower and closer to the floor? Do you have to wait for the blades to stop to exit the craft? Unlike a normal helicopter?

They're driven by the same motor, so what is essentially 2 timing belts keeps their rotations the same, and as long as they're offset slightly, the belts/engine can keep them in their own individual spin, which does not intersect with the other blade.
