I am building a quad with mostly DJI internals and want to put the ground station and the video transmitter (Boscam 600mw) in the same place.  Can these two things be near each other?  The Boscam uses 5.8Ghz; I think the GS uses 2.4 Ghz, yes?  If so then there shouldn't be any interference between them, I think...

Correct, our Ground Station are runing 2.4GHz or 900M
