Hey guys! We actually work on a UAV project which needs pretty fast, autonomous flight capabilities. Basically we want to reach up to 100km/h (27m/s) in a waypoint mode and were wondering whether there are any limitations with the autopilot that would make such an operation impossible? I would be …

There are no limitations. We’ve flown a lot faster in the past.

Great to hear! I was wondering, as the MPC_XY_VEL_MAX parameter only allows a maximum value of 20m/s… So this can be overridden?

I think QGC will give you a warning if you want to go higher but you can just check the box and set it to the value you want.

How do you set the speed for your flight? Are you using simple mission points?

oh nice. is it possible to set this parameter for setpoint_position in offboard mode? or is it just for missions? in my understanding missions are the same like setpoint_position, but you interrupt the “mission” (offboard), when you set a new point.

@TobiasM did you find a solution to this? I’m in the same situation that I want to bypass the 20 m/s limit in offboard mode.

just set the max value in qgroundcontrol to a higher value.

What’s the maximum speed that you have flown? Please consider the latest cases too.

Hello，is it possible for px4 drone to fly more than 300km/h?

@TobiasM You can add additional entries to the mission which change the default speed.
