YouTube user Anton Valagin posted a video of the flight of a model of a promising Russian fighter Su-75 Checkmate (“Checkmate”). The video demonstrates the operation of a scale model of an aircraft and its design features.
Judging by the foreign speech behind the scenes, the scale model of the aircraft was not made in Russia. Externally, the model is a detailed copy of a sample of the Su-75 Checkmate fighter, presented at MAKS-2021. So, the movable nozzle of the engine of the model simulates the controlled thrust vector, and the fully operating elevators and rudders repeat those on the Checkmate model.
