How to change the default takeoff altitude

[BHU6]

Hi,

When I use the code to control RTF. It always fly to 20 meters and then to the target altitude.

How to change it？Are there have any ways to let RTF takeoff slowly?like controlled by RC?

vehicle._master.mav.command_long_send(vehicle._master.target_system, vehicle._master.target_component,

mavutil.mavlink.MAV_CMD_NAV_TAKEOFF, 0, 0, 0, 0, 0, 0, 0, aTargetAltitude)

Thanks.

Hi Yermi,

I used the QGC to connected the RTF. When pressed the takeoff button, the RTF moved to about 15 meters altitude and then moved to the 2 meters altitude.

Hi philipbinbin,

Thanks for your patience. We have tested the takeoff feature on QGroundControl with the Aero RTF and did not observed any irregular behavior. The drone took off at 1.5 meters/s until it reached an altitude of 2.5 meters altitude which is the minimum altitude. Once it's hovering, the altitude can be changed. We recommend updating to the software image 1.4 and updating the flight controller firmware which is included in the new image. Once the drone is updated, please do a full frame reset and calibrate the drone prior to flying.

To adjust the takeoff speed, you can change the parameter MPC_TKO_SPEED. Please note that changing parameters should only be done by advance users and may lead to issues. We recommend contacting PX4 prior to making changes.
