Firstly please don't beat me if this has already been posted as can't find it.
All righty then can anyone answer this or know with the dual control system set up and operating can the GPS in the slave control be set as the dynamic home point as this could have the potential for for some great uses as to take of with the master in one location and finish with the Slave as the home point so during an arial operation the camera operator is the finishing location of what you are doing.
Does anyone know?

Not sure of the specific answer to your question, but note that the maximum distance between the master and slave controllers is 50 meters.

The only communication between pilot and craft is through the 2.4 GHz link of the Master RC. The camera op, working Slave RC, does not have a link directly to craft, but uses 5.8 GHz link to Master RC to send signal to camera/gimbal. So no, Slave cannot determine dynamic homepoint, only Master.

Have tested it and yes slave controller can determine dynamic homepoint~
But just like @abe said the maximum distance between the master and slave controllers is 50m.

Thank you for that food for thought 5.8 Ghz range extender and relay might be worth toying with when mine finally arrives
