I'm told I can't use two cameras on the phantom 2 each sending footage to a switchable iosd mark 2. I'm told the mark 2 will work with the drone as far as data loging and telemetry but it won't allow me to use two cams and switch between them. Something to do with with sbus. Can some one tell me if thats the case and what I can do to work around? Could it be as simple as changing the flight controller from a Naza-m to a naza-m v2 or something else?
