How to set flight speed for flight plan

I set some waypoints in flight plan, but don’t know how to set the flight speed from one waypoint to another waypoint. :question:
Can anyone help :question: :question:

There are a couple of ways. Adding a DO_SET_SPEED command to your mission will set the target speed either for air or ground speed (you don’t say if you are flying a plane or copter). Note that doing it this way means the target speed will remain at this value until you reboot the autopilot, or add another DO_SET_SPEED.

In plane you can also use ArduPlane:TRIM_ARSPD_CM to set the target airspeed permanently. Using DO_SET_SPEED will still override it if added into a mission.

Be careful of setting speed too low for planes, your aircraft could stall.

There is a command [ do change speed ]. use it in between waypoints .
Here is a link to the mission planner info
I have not yet used this feature.
There are differences in the required parameters used for Copter, Plane & Rover.

thank you, let me try it this weekend.

thanks, I am flying copter.

My apologies, as pointed out, the command is DO_CHANGE_SPEED not DO_SET_SPEED

I try to use DO_CHANGE_SPEED on my plane, but still after passed that waypoint its speed not change…

Did you manage it…i am also working in this and nothing at all.
