The Zerotech Dobby was the first selfiedrone introduced in the market and already offering a 1080p EIS lightweight solution. The main drawback of the Dobby is probably its poor flight time.
Here is the successor of the Dobby: https://www.banggood.com/Zerotech-Hesper-WiFi-FPV-4K-Camera-One-Axis-Gimble-With-EIS-Mode-Foldable-RC-Drone-Quadcopter-RTF-p-1283962.html
The Hesper is now a 340g machine advertized to fly about 18min. It’s a foldable machine as the dobby. Here we still have 1080p@30 fps video recording with EIS but a 1-axis gimbal is also introduced to tilt the camera. The video transmission is done on both the 2.4Ghz & the 5.8Ghz. I really hope there won’t have problems with europeans 5.8G channels. The FPV live flux is in 1080p format with a nominal latency of 220ms. The Hesper also added a VPU to improve altitude hold stabilization. As advanced flight modes we have the classic orbit mode, target tracking. No specific selfie flight modes announced but it can be added by a software update.
The Hesper can be controlled directly with a smartphone up to 120m of controle range or 800m with the specific radio command. With the radiocommand, the machine is sold slightly less expensive than a DJI Spark… but I am not sure that the EIS will be as good as the 2-axis gimbal+EIS offerered by the Spark. IMHO the Hesper must improve all software features to become a real DJI Spark competitor.
