I read on the DJI website that the Lightbridge on the Inspire 1 is a improved version compared to the stand alone Lightbridge. My question is..what are those improvements? Since as far as i know the Inspire 1 has a 720P Liveview while the stand alone LB has a 1080P Liveview? That part at least doesn't look as an improvement. Do they mean the possible up to 300 meters extended range compared to the 1,7 Km for the old LB, or are there any more improvements?
