I have previously had nothing to do with such things, but the videos on YouTube have enticed me to buy the X4. I am not accustomed controller anyway, because I have no game console. I did not think that it's so easy. On the third day I am then become overconfident, and he is out of my Ca. 50m height popped onto the tarmac. The arm is broken. I stuck him with adhesive tape again. Again, I was surprised that he was still flying. Have the arm adhered totally wrong. The gyroscope controls from super. Approximately 30 minor crashes later but the veins are then demolished. I have now ordered two more ..... Then I immediately also a spare parts store :)
