The F11 4K Pro is definitively an improvement compared to its predecessors. The combination of EIS and 2-axis gimbal allows creating smooth, almost cinematic-like, aerials. Actually, it is the first drone under $200 with a true 4K camera that I reviewed for now. Battery life and control range is comparable with the one any drone in its price range has. The lack of an optical flow sensor makes the F11Pro 4K to drift a lot indoors. Outdoor, with good GPS coverage it is very stable, but still doesn’t hold its position all the time. RTH worked well, but is not as accurate as my DJI drone’s, it missed the landing pad by few meters.
