In everything I've read so in other recessions, it occurred to me that the very satisfied and had a lot of fun with the part had, while others have tried desperately to get this machine in motion. Here equal to the solution of probably the error that is most committed. First of all, I had the problem that the remote control did not want to connect to the Quadrocopter and vice versa. Blink, blink, blink, it was not a permanent light. Only eventually worked the thing anyway (coincidence?). And how many other customers, I wanted to return the unit again. Here it comes: In the manual is that after switching on the remote control you must move the left stick once back and forth. Thus, the remote control is initialized and finds the quadricopter within a few seconds. People and now the fun begins. The thing you can do right after some practice capers and consider yourself from the air sometimes, because the video camera works well. Likewise photos. Now of course you have to make compromises in terms of quality of Aufösung. But you can of a toy and not expect to have a quality like a Aufklärungsdrone to the police. Should you practice outdoors before trying to train with the quad only once in the apartment levitation experiments. Incidentally, the battery, hold between 5 and 8 minutes, depending on how aggressive you are flying. Replacement batteries definitely a must in order to increase the fun factor. Conclusion: a toy for old and young, great fun and works great. A small addendum: The device is me crashed from about 20 meters on asphalt. Nothing happens, then flown on the same. What more could you else ??
