Hello all,

In previous firmware there was a option to pick GPS or Barometer or both for altitude control I have noticed in the new firmware this has now been removed, does anyone know how altitude is now controlled in the code GPS, BAROMETER or both?


Regards to all as always.

    Hi Marc,

    I presume you are referring to the ALT_MIX parameter?

    That hasn't changed at all, so I'm not sure what you mean about it being removed.

    I don't actually recommend you change it from the default of 1 though. GPS altitude is notoriously unreliable, and there is a good chance you will crash if you use it. The only thing it's really good for is things like high altitude balloon drops.

    Cheers, Tridge
