Qland vertical speed

Julien_Theodore · April 12, 2026, 11:13am

Hello everyone,

I’m currently having an issue with the Qland function (on a Taillister drone without a surface) regarding the descent speed. The speed is set to a maximum of 2 meters per second down to a height of 6 meters, but it turns out the drone is descending at more than 5 meters per second after transition from qhover (where vertical speed was 2M/s)to qland, which I can’t explain with the current settings. Does anyone have any ideas, please?

@Julien_Theodore why did you compile out EKF3 and compile in EKF2? Did you make any other code changes?

Hi @Julien_Theodore,

Any further updates on this? I think we can’t make without more information..

Txs for the report though!
