We are currently testing a HereLink system to control a gimbal and for the HD video downlink from our camera.
There is a issue im observing where it looks like there is a small lock up in the sbus output. eg if i pan the gimbal around there is a small stall in the signal which causes the gimbal to stop moving for half a second.
We were using a Futaba radio to control the gimbal and never had this issue. The HereLink is a fantastic way to combine video and control over a long distance.
