This model is actually with one of the best of this size that I have ever tried. I actually like the Quadrocopter much, but after only one month of the LiPo is so exhausted that he reaches 1 minute 12 seconds by holding until the display flashing LEDs that he can not. Otherwise, he is really good: - Small - Robust - Easy to fly - Different flight modes - May flips in all directions - Has LEDs everywhere I flew him much in the office and Birthday colleagues have even set up an obstacle course in the office. Too bad we had it all already grown fond.
