@Alex-Kushleyev I do not have the drone itself yet. Is there a CAD model I can use to measure the dimensions I need?

I am a Berkeley student currently building a drone simulator in which I want to include accurate drone parameters for verification purposes. I would ideally like to reference the parameters of the M500 drone. I am aware the mass is listed as 1075g with battery (820g w/o battery). However, I also need the arm lengths (the distance from the center of the drone to the axis of rotation of each propeller), the maximum thrust of each rotor, and the constant that relates the (approximate) drag torque of the propeller to its thrust.
