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.)

Review of JDRC JD-65G WiFi FPV Foldable Drone With 1080P Camera Optical Flow Positioning RC Quadcopter


Box came a little beat up but luckily quad and contest of the box is intact.




Quad looks really nice and its super compact when folded. Think that choice of foldable arms against foldable propellers is great because fixed props are more robust and should be more balanced than cheap foldable props.




Quad flies perfect, holds height and position flawless and gimbal response on remote is very nice and smooth:

Review of Eachine E511S GPS Dynamic Follow WIFI FPV With remotely tiltable 1080P Camera, 16mins Flight Time RC Drone Quadcopter - 5G WiFi 1080P

First, Happy New Year to all my friends on RCGS!!!




Second, E511S from Eachine just came to me on last day of 2018. Quad flies great "out of the box". Height hold and GPS position hold works perfect. And, for the first time in this price category, I see motorized camera tilting mechanism which is controlled via two buttons on the remote. This is most welcomed function as its always necessary to change angle of cam during the flight.
