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.
