    Hi everybody,

    I am new here!

    Ok, I did some modifications to my phantom 1: I changed the remote to a Graupner MX 16 and fitted a tarot gimbal.

    Everything works fine, the new remote is nicely calibrated in the Nazam. Did some first tests yesterday:

    Without the gimbal/cam it worked good as expected.
    After changing the battery and attaching the gimbal everything was alright at first.

    NOW: After 1-2 minutes the phantom started slowly to loose height. I could hold the height manually by giving extra gain and I could definitely fly for 5-6 minutes like this. The batteries were definitely not the problem (multiple batteries, fully charged, etc.)

    Mode was set to GPS.

    I always assumed that the Nazam Module would autoadjust this when hovering ...

    Is there any way to "obstruct" the height sensor? How is the height measured anyhow?

    I am happy for every help here!

    Best regards, Peter
