The original UPair One or Chase product line was purchased by another company, G10, where the UPair 2.0 is now sold as the UPair G10. The company will soon be selling a new model with a built in camera instead of the Firefly (GoPro clone) on the earlier models. While no replacement for a DJI Phantom 4, UPair offers a lot of nice features for the money (around $400). The 7" monitor is built-in, the control battery can be recharged and has its own balancer, it has "return to home" switch, camera remote controls and gimbal control, 3 flight modes, it uses "standard" DJI 9450 props, and has a nice direction indicator function on the monitor.
One detractor, the on-off switch is not as described in the manual: "Off" on the switch is the far left, not center as described in the manual. Mostly good reviews on YouTube. Good back-up bird. All but impossible to find a suitable case, though.
Yes, I have one; yes, I like it; yes this information came from my contact at the factory in China.
