After only a few flights in the open I was about 100 grams, the little machine under control. It is important that as possible should go no wind. Because that little plastic is quickly blown and can then hardly reasonable control by the wind. Twice fingered my neighbors thankfully the aircraft from their flower beds. Caution: Be sure the laws in film flights note!
The copter is powered by a 500 mAh battery. The battery allows approximately a 10-minute flight. By then gives the flyer of a beeper and the pilot to land quickly. For charging the battery takes about one hour. An appropriate USB cable is for Copter and camera on. I use the charger of my Samsung Galaxy Tabs. A second battery is advisable in any case. The cost around 15 euros.
Really remarkable are the photographs of the mini-camera in HD quality - assuming good sunlight. More can be read here and see: [...]
So far I have broken a chassis and an engine. The Parts I ordered for simplicity at a major electronics retailer.
A disadvantage is that the beeper, the battery signaled the end of its force is barely audible. It is not clear to me until now, on how many meters of contact between the controller and blade remains secure. Battery charge and radio contact would be displayed via optical signals to the controller.
Bottom line, the blade is not only a great toy, but also helps to train fine motor skills and reaction speed.
