everything that we can and we try to fit parameters to it based on flight data and then I think that's that's pretty different from other types of robots that are more like especially when you're dealing with contacts and more complicated things but this is not that many degrees of freedom there I think the complicated part comes from aerodynamics so once you're once you're flying fast and you're in turbulent flow and you get these types of like pitching moments and the accelerations your rotors play into things so that there is
