Este es el comentario del video de Youtube al que me refiero:
Okay, I think I know the problem. There is a ribbon cable inside the zenmuse that uses it’s tension to determine where to stop when moving the camera to up position. It is possible for the ribbon cable to be accidentally moved into a spot that pulls some of the slack out of the ribbon cable and stops the camera movement before it can fully move up into position. The cable is hidden between the motor and the gopro in the black cylendar. There are two very small screws to remove the cover and reveal the cable. The cable spirals around the barrel of the cylendar. If you follow the cable spiral up to where it makes a 90 degree turn, that portion where the 90 degree turn is can be accientally «pulled over» the metal piece that should protect the cable. If you follow the cable, it should be «under» the metal outcrop protection piece, but the cable can be accidentally moved on top of this metal outcrop, therefore pulling some of the slack out of the cable and not allowing the camera to move up into position. Be very careful. I ripped my ribbon cable attempting to find the problem! So, to boil it all down, your ribbon cable is snagged causing to little slack in the cable for the gimbal to fully rotate. Hope this helps.
