Equipped with a landing gear, the Bi-Convex Rotorwing is able to take off and land on a grass ground.
When starting, the tail of that flying object lifts first, followed by the frontal section...

Have a look to the video:

Incredible!
Definitely it's one of "things which shouldn't fly".
I have a name for it - "Grass mover".
