This is the new head gimbal unit. It has more movement interval, and it can support heavier cameras.
In the previous version there was a high load on the servos. This current build reduced the load. (previous version)
We changed the servos to MG995, because it has metal gears, and we hope this solution will be more durable.
At the base plate we upgraded rotation servo connections with proper bearing. It has more weight, but the whole head is more stable.
