I want to know what is the maximum flight speed limit [horizontal] for Pixhawk? I am using a Y6 coaxial hexacopter and the value of parameter ‘MPC_XY_VEL_MAX’ is 12 m/s but even if I increase this speed to max 20 m/s, I still get a top speed of 12 m/s in Gazebo simulation. I also changed the ‘MPC_TILTMAX_AIR’ to 50 deg but copter does not tilt beyond 45 deg. Is there any other parameter I need to change in order to achieve this, or how can I solve this? Any help is appreciated. Thanks!
