I get the feeling from the posts above that having two antennas is not really an advantage as far as range and that is the main reason I might put the board in and since I have the board. But then I hear that if that receiver board was installed then my transmitter might not work with it. Humm... I think I want to put a zenmuse gimbal, so I would need an upgrade board I understand, and install the tilt control in the transmitter, don't sound very hard. I just got my gopro so the gimbal is the next necessary upgrade.
Thanks you guys for your tips.
and to ozzyguy, I think the progression of Phantom is V1 then V1.2 then V1.1.1. What I find interesting is they arn't listing any of those as current versions for sale at the dji website. I guess, like windows 3.1 or 98 etc. they have stopped making them. I wonder what that means for Naza-M support in the future?
