Hi all, Just purchased the ground station here: http://www.amazon.com/gp/product/B00FEQG25C And I noticed this package doesn't come with an iosd mini. I never purchased an iosd as I have no real use for it, just been looking at the fpv screen. Question is, is an iosd mini needed to use the bluetooth datalink with gs? I haven't been able to find a straight answer. Thanks!
