I am trying to evaluate systemid mode in sim vehicle. I am taking off in guided mode, switching to acro mode, and then systemid mode. When I do this in mavproxy console, I am able to adjust rc 3 pwm to a trim value to stabilize the altitude. But, when I do this in python / pymavproxy, I can’t get the vhicle to trim and it falls to the ground. The goal is to use mixer inputs, pitch / roll / yaw / thrust, to get the 6 dof system matrices for the quad, in sim, and then in flight. Any suggestions for that goal would be appreciated too.
