Review of Xiaomi FIMI A3 5.8G FPV With 2-axis Gimbal 1080P Camera GPS RC QUAD


Review of Xiaomi FIMI A3 5.8G 1KM FPV With 2-axis Gimbal 1080P Camera GPS RC Drone Quadcopter RTF - 5.8G FPV



This is first time I see that high level quad like this with 1080P 2-axis Gimbal Camera uses analog 5.8GHz RF signal for video transmission. That means that along built-in monitor in remote you can use any 5.8GHz receiver/monitor or FPV goggles like this skyzone one I have and optionally combine ti with directional antennas like this to get better range.



This should be very interesting. Here is 1km range test (stuff use to record it is in video desc.)

Mine are in 2m30s clips. Some drones do that, met a few.
