This is the quad that I flew at Drone Worlds 2016.

The Atmospheric Adventures Kratos is a pure racing machine. The designer, Bulbufet, originally set out to create an airframe that he wanted to fly and solves all of the major issues that he has had with existing options. The two primary concerns were (1) lowering the camera towards the ground while still protecting it against damage in crashes, and protecting the VTX from all possible damage that would be caused by an antenna taking a large hit. Beyond that, thinking about the Kratos as a racing machine, we decided to support 5” and 6” propellers, and develop it as a “stretch-x” frame, which is the ultimate racing form-factor.
