I advise clearly from getting the blade to buy 350 QX2! I am already flown him frequently. From flight behavior forth the thing is really great! Even absolute beginners will get away with it completely free to your as long as you do not overdo it and take it slow! For negatives: I started the Blade 350 one day on a field. Batteries fully charged GPS log successfully, so far everything fine. After 2 minutes of flight time flyer tilts by about 45 degrees, full throttle and flies away! No more reaction to the remote control! After 2 minutes I lost sight. A friend tried to pursue him (unsuccessfully). The rest of the day was spent looking (unsuccessfully). Then I then contacted the manufacturer and the answer was: here it will have in fact been a technical error ... we can try to find the problem, if you send us the Blade The Hammer! Sustaining the error and tell me that you could see me, what was the reason when I send him! How then, IF HE IS flown ?! After I distributed figurehead, a search ad in the newspaper started, I actually had a bit of luck! After 4 weeks, someone who had the Blade reported found without any damage! The next day all the batteries charged and made a cautious test flight. Everything worked flawlessly. But confidence was gone! I sent the blade thus back to the manufacturer, who could not find a mistake, contacted me and wanted to return the blade to me. But have I no longer wanted him. The problem is that a fault can only determine if at the time of the review, there is also (for example, a loose connection if it's there, I can find him if he makes at the time the analysis is not noticeable, it is also hard to find him). Finally refused the manufacturer to keep the blade (money back), and sent me on a completely new model to. Personally, I'm the new fly and not to resell. The trust is just it. Whoever thinks that I was a single case of mistaken! Give love to yourself, at YouTube or Google a: Blade 350 Fly Away Please note: All videos that they find only those could upload, who rediscovered the Blade! Also being discussed in several forums about it! Therefore, again! I advise against the purchase of all the Nachgängermodelle and the Blade 350 QX2! Do not rule out that you are a victim of fly aways. Good to know: The Blade 350 should generally not be used in conjunction with a GoPro camera and WiFi enabled! He komuniziert over a 2.4GHz frequency, just like the WiFi feature of GoPro! Even with the supplied copper foil I would advise everyone, WiFi function OFF!
