I admit it...I am no rocket scientist but.... Am I the only one in the world scratching my head and wondering why Yuneec or even some of the other Drone makers haven't come up with a model that has 2 batteries that you plug in side by side so that they can run parallel? When one is flat it could automatically kick over to the next one. Surely the extra weight being carried would be worth it as your flight time would be almost doubled? Yuneec...if you're watching this....feel free to take this idea and run with it!!!!!!!!!
