According to my testing on the Mi-290 Taru, here is what I have come up with:\n\n```\n[\n    [rotor 1 roll +right/-left, rotor 1 pitch +down/-up, rotor 1 collective +up/-down],\n    [rotor 2 roll +right/-left, rotor 2 pitch +down/-up, rotor 2 collective +up/-down]\n]\n```\n\nWhen yawing left and right, rotor 1 and 2 collective differ from each other. This is normal behaviour with coaxial rotors. Yawing right increase rotor 1 collective and decreases rotor 2 collective. Yawing left does the opposite. Rotor 1 in this example seems to be the bottom rotor."}]}
