Nice. Birds can also rotate their tail relative to the body, and if you watch videos of them, you can see they use their head and wings independently relative to their body to yaw and roll.

I wish i could built something like this one day

Look at bird feathers you could improve lift on down stroke and push air in and under body of plane. The mid rib on feathers is off center A gap opens between the feathers on the upstroke.

I wonder how big it has to be to pick up a person. (Then you can make a kind of jetpack with it!!! )hehe

It looks to me that including the VN-200 is what extends this from a mere RC model into an actual robot.

You might get some weight savings with a V tail.
