    HI is there a way to calibrate or verify that the altitud value is accurate in the OSD before flight? did a number of flights a few days ago at sea level and before take off my altitud number on the OSD shows a negative value here is a picture of the OSD screen at my office

    That's odd. My understanding was that the barometric sensor was re-calibrated each time you fire up the motors. Does the OSD-reported height stay negative if you start the motors and just leave the ALTA on the ground with the motors at idle?

    Also, does the OSD-reported height change (getting less negative) after take-off?

    Hi Andy you are absolutely right I did a test this morning as soon as the motors start the correct altitud value sets in,
    thanks

    Thanks. Please make a note of the date and time. Today I was right! :) It doesn't happen often!
