The DJI Mavic Pro is a marvel of technology that records breathtaking 4K video that is worth buying a 4K screen to view. But it should not really be seen as a model aircraft. Rather it is a flying camera that can do some amazing things.
In an attempt to learn something about drone racing, I bought an Align MR25 race drone a little while ago, along with a Fatshark Dominator V3 FPV headset. This drone is a lot of fun, but not a serious competitor for drone racing.
