Set Airspeed ratio not possible

Posted by Richard Kirnbauer on February 18, 2015 at 12:44am

Hi!

I tried to set the airspeed Ratio Parameter with Mission planner (arspd_ratio) but it is not possible. If I change the value in full parameter list, the field gets red and I can´t write it to apm.

Does anyone know, what´s the reason for that?

I have  MP 1.3.17 and the newest Firmware of APM Plane.

Thanks a lot for help.

Greetings

Richard

    APM:Plane has an automatic calibration function that will adjust the value of ARSPD_RATIO automatically provided the plane is flown with frequent direction changes. Look here in the wiki.

      Thank you for your answer.

      I used that automatic calibration function, but got a bad value for ARSPD_RATIO and want to set my old value again.

      Is it not possible anymore to set the value manualy?
