Got for Christmas the helicopter. Since then, he is in daily use; evening - after work - several rounds are flown. That such a small part as much power has, is quite amazing. Starting with the battery bishin to the sensors in this small helicopter; TOLL. The controls are good to handle. The helicopter moves after some practicing very quiet and constant in the air. The flight takes between 5 to 8 minutes. After about 30 minutes charging time again. This is unacceptable! In crashes directly the "gas" away; so greater damage should be avoided. The Amewi 25042 is a good test object, man / woman on the indoor flying is fun and interest. The value for money is great! - I look forward every time the "Grasshopper" is flying and my wife, in spite of that she has of this technique no big clue me this part gave. The Amewi 25042 is recommended.
