Let me be clear. There was NO wind. Batteries were all NEW. For absolutely NO reason the H2 just decided to fly back to China. NO response to Transmitter input, NO response from screen input. No response to power down. I lost control less than 20 feet away. Luckily it is only light and flew off towards the moor but god knows were it ended up. https://www.geekbuying.com/item/SHRC-...
