    A car with four wheels can get puncture in four wheels, so you have more points of failure than a motorcycle.

    We can build helicopters with one engine. Adding five more engines doesn’t necessarily 5 points of failures but 5 backup engines. I tried to point out that your example is not exactly right in this case.

      Sigh, with regards to drones, they use the torque from the motor to steer, they are also very finely balanced, so a motor dying in flight will make it fall from the sky.

      Now, this is clearly different from this device as it has (small) wings and the engines in the picture are all pointing diagonally in the same way, meaning that some lift is generated by the wings.

      It might be enough to land in an emergency if an engine quits.

      But a normal quad or even a hexa drone will just crash or start spinning if one engine quits.

      But I am man enough to be swayed by evidence, so show me a drone with one engine quitting mid flight that doesn’t just crash.
