Seems we better be careful with gimbals and the phantom's compass position to avoid flyaways.
Would somebody do this test with H3 2D and H3 3D please?

But that's why you do a compass calibration whenever you add or remove any new hardware to/from your setup, so the compass can compensate.

I forgot to calibrate in all the excitement of getting my H3-3D rig airborne but as I always do a test hover I saw it toilet-bowling. Brought it down, did calibration, hover was then good.

All right, thank you, wasn't sure if calibration is enough for this.
