I am building a 2-axis gimbal using a SimpleBGC.
The motor for the roll axis moves one arm which holds the motor for the tilt axis and the attached camera module. Of course, this makes the roll axis unbalanced and puts high load on the roll axis motor which gets quite hot in the process. After talking to Basecam's support, it gets pretty clear that I have to put counterweights on the tilt axis to properly balance it, so the motor does not have to hold the arm up all the time.
Now, when you look at many ready made gimbals, e.g. by Tarot or at cheap noname ones (e.g. this), you see that they aren't balanced. Why don't these models use balancing while mine doesn't work without? Do they know a special trick to cope with imbalance or do they simply accept bad balancing in favor of smaller weight?
