Hello everyone. I need your opinion about my drone concept.
This is a hybrid of airship, quadrocopter and airplane:
the cylinders ("body" and "wings") are filled with hydrogen; on top of them are solar panels
the box in the middle stores batteries and electric motors for the vertical propellers
the horizontal propellers are powered by electric motors located in the cones at the end of "body" cylinders; the motors move inside these cones to change the direction of flight and for turning the drone around
Your comments are highly appreciated.
