Sky Armor

What caught my eyes is the unique way the propellers are placed and positioned. By aligning them at an angle, it allows the toy to change directions without the need to tilt like normal helicopters do. This could be a very good function for real life helicopters.

However before you get too excited and go design another concept helicopter, this is not a realistic way of doing things because it results in the blade ending lower than normal. As a result it

(1) needs bigger open area to land

(2) the propellors have to stop moving before anyone can get in and out of the helicopter.

I can think of a couple more points but just these 2 points are enough to make this a stupid idea for real life applications. Obviously we can solve the problem by simply placing it taller, this results in a helicopters becoming much taller itself, resulting in

(1) more materials needed

(2) more weight

(3) increase air resistance?

Actually i've thought of a better solution by making the motors tiltable, but it meant that it probably will be more of a hybrid of a plane and helicopter as it requires clearance between the 2 blades.

Anyway this robot needed this because it is standing up and way harder to make it change direction by tilting.
