When standing on the ground there is a gap between 5 and 15 degrees with the horizontal .. I tried to adjust by gimball Roll adust and set the gap to 0 but when I move it again it becomes out in the same old gap (5-10)

Firmware issue??
software Issue??
hardware???

the gimball turns up and down perfectly and when rolling the spark it keeps always this 5-10º gap...   working all fine except for this gap...

updated all, app, RC and spark..

Any solution??

Could you please post a pic or a short video about this issue for better assistance?

i had to adjust the gimbal roll to -1.0 even after doing IMU calibration
