Great hi-res/hi-rate camera...
Conclusions: Very good higher-resolution/frame-rate camera (4k, 2K, 1080P) at same price-point as the typical lower-resolution cameras. LOVE the gyro-stabilization option. The battery is the one weak point, mine does not last long. Plan on using the included USB adapter to power this camera from and external power source, on a radio controlled plane, use the flight battery.
For those who know what FPV is, there is a basic OSD built in for camera data, and you can turn the camera on/off remotely (R/C) over
