    My ALTA is new and I've only done a couple of test hovers with it. However, when on the ground, my OSD is saying that the height of the aircraft is -54m ! This is worrying because it could cause the aircraft to descend way faster than it should on RTH. I'm not willing to try the RTH until this is fixed.

    Does anyone know how to recalibrate this? Thanks

    Is this before you've armed the copter? I see that until I put the copter into an "armed" state. Once armed, you should see that number go to near zero. Do you have the ALTA mobile app? I'd connect that up and see what the status screen says about errors.

    Ah, looks like I spoke too soon! Arming the motors seems to reset the altimeter. Thanks Steve. Case closed.
