Now when you put 2 batteries gimbal ,camera ,av converter, fpv, another small 3s , etc,for all the extras, what is the best way to make sure it balanced? Thanks so much,
I balance my copter without the gimbal, I then balance the gimbal by itself, and the put the gimbal on the copter and recheck balance. I hang both my copter and my gimbal to my ceiling and allow it suspend freely which makes it very easy to move weight around and see how it affects the balance.
