Banggood sent me an Eachine Fatbee FB90 to review. It's a 2S brushed quad with ducted propeller inspired by the Blade Inductrix.
I have the DSM version and flying it with my Devo 7e.
I flashed it with Betaflight 3.01 and below are my PID & Rate settings.
You can order the FB90 here: https://goo.gl/LIau4u
