Coaxial Dualcopter mk II - almost like RC SpaceX Falcon 9 thrust vectoring rocket

This is 3D printed coaxial dualcopter made from common multirotor parts.

This is how it flies: https://youtu.be/lt3TfAiue1Q

* Thrust and yaw control is provided by 2 counter rotating propellers
* Upper motor is 2205 2300KV with 5x4.5x3 propeller rotation in CW direction
* Lower motor is 2205 2600KV with 4x4.5x3 propellers rotating CCW
* Flight controller runs INAV 2.0
* Control surfaces are rotated 45 degrees from long axis to fit servos
* flight controller is also 45 degrees rotated
