Takeoff Height less than 3.0 m

PX4 Autopilot
1

Hi Everyone,

How can I make a quadcopter takeoff to a height less than 3.0 m (say 1.0 m)?

I set the MIS_TAKEOFF_ALT to 1.0 m, but when I click the takeoff icon on the upper left corner of the QGroundControl screen, a slider shows on the right with minimum Height (rel) of 3.0 m.

QGroundControl: 5.0.7

PX4 firmware: 1.16.0

Have you rebooted the vehicle after changing MIS_TAKEOFF_ALT
