You need to wait awhile, until they get them right, I got a set of 3 but getting gimbal overload, the video from them is amazing and no problems with them staying on. Demo video here.
ya im going to be picking up a complete package of filters in the state side when they fix the issue with them freaking the gimble out..
i think DJi could also work on it with 3rd parties.. like add a filter mode or something? i dont know.. something where gimbal is expecting additional imbalance of xx grams.. so when that is activated it recalibrates with additional imbalance and is ready..
