They wouldn't sell it separately for 400,00 as the cristalsky 5.5 alone is priced at 469,00. They sell it for 400 more when purchasing the mavic 2 because it comes basically as a upgrade. I ve bought my mavic2 with the fly more combo and surely I paid less than if I had to buy apart the itens that come along with fly more combo. What I totally disagree with DJI is advertising this controller as a Ultra Bright. The controller reachs 1000cdm2 which is considered as high brightness for cristalsky devices, the Ultrabrigh should reach 2000cdm2...If you order a new Mavic 2 Pro or ZOOM, you have the option to also buy the new Smart Controller for just $400 more. So why does DJI jack up the price to $649 if you already own a Mavic 2. A lot more people would jump to buy the Smart Controller priced at $400 but in my opinion $649 is WAY over priced$$$$$$
