DJI Mavic Air or the radar which is more interesting?

Lots and lots being said about the traditionally leaked new DJI Spark/Mavic mashup, to be launched tomorrow in New York. Leaks are a DJI thing, happens every time. Is it a new Mavic, is a bigger Spark. All will be answered soon. I want to know about this FCC filing for this RD2412R1712 High-Precision Rotation Microwave ["]
