Hey I would like to buy a few starling2 max .

1. Is it possible to connect a gps module to the drone for redundant localization solutions?

2. Is it possible get an explanation about the 2 different RC configs and the different possibilities of RC remotes
as it will be difficult to buy radio items with our customs in the country

3. what are the options of live streaming of video to the ground station

1. The starling2 max comes with a GPS already attached
2. The voxl2 supports multiple methods of RC including: SPEKTRUM, CRSF_MAV, CRSF_RAW, and GHOST
3. The voxl2 and the starling 2 max already streams it high resolution camera to most GCS's through its rtsp stream - so this is a feature that is already supported on the starling2 max and voxl2's with cameras.

@elad-applepar For question #1, if you are talking about adding a second GPS for redundancy then it is possible depending on which GPS unit you choose and which configuration option you choose for the Starling 2 Max. The GPS unit would have to be UART based, not CAN or SPI based. And you would need to choose the WiFi configuration of the Starling 2 Max because that has an add on board that exposes a UART connection. Then you would need to enable a driver for the second GPS in PX4. This isn't something we have tried but it is theoretically possible to do. I would only undertake this if you are comfortable modifying drones and dealing with px4 configurations.
