NEWS: C-fly Dream

[Drone News]

Remember the C-fly obtain, a clone of the DJI Mavic ?. A complete desaster in most points: poor fligh time, poor gimbal stabilization, poor camera performances, poor software…
Today, they present a clone of the DJI Spark with the C-fly dream: https://www.banggood.com/C-Fly-DREAM-GPS-WIFI-FPV-With-2-Axis-Gimbal-1080P-HD-Camera-Optical-Flow-RC-Drone-Quadcotper-RTF-p-1321873.html

A 250g machine with a 2-axis stabilization system like the spark… but no mention (and it’s probably not the case) about a potential Electronic stabilization for the yaw direction like the spark. The flight time is announced about 15min, probably 12 maximum in practice. Another important remark… Like the Obtain, videos are shooted in 1080p resolution but no frame rate mentioned. I bet it uses the same sensor with a maximum of 24-25fps!!!! so clearly very choppy recordings in practice. The control is done in the 5.8G band so probably incompatible with some europeans android devices if no channel selection can be done. Ok it’s twice cheaper than a spark but IMHO, it’s urgent to wait first feedbacks about this machine. I am afraid, it will be another DJI wanabee failure…. Wait & See.
