Unable to Reach Expected Speed in Altitude/Position Mode (PX4, 10-inch Quadcopter)

PX4 Autopilot
1

I’m new to drone building and just getting started. My goal is to be able to fly stably in Altitude or Position mode at a speed of around 30–35 m/s.

Currently, I’m building a 10-inch X-frame quadcopter using a Holybro Pixhawk V6 Mini flight controller.
When flying in Altitude or Position mode, even with full throttle, the maximum speed I can reach is only about 22 m/s, although I have already set the following parameters:

  • MPC_XY_VEL_MAX = 30

  • MPC_VEL_MANUAL = 30

  • MPC_TILTMAX_AIR = 60

  • MPC_MAN_TILT_MAX = 60

At hover, the throttle is around 30%, and I have also set:

  • MPC_THR_HOVER = 0.30

I’d like to ask if it’s possible to push the speed higher, because I can see that the motors are not yet running at full power, so theoretically the drone should still be capable of flying faster.

Thank you very much for your help.

You are likely exceeding the actual drone’s capabilities trying to achieve these sorts of speeds. Or you might have to improve the tuning.
