Some people say that this aircraft is faulty but we all the same buy two aircraft of this model
proper functioning (not defective) .We can not fly as soon as there's wind is the wind that controls the aircraft.
* STABILITY: To adjust the stability you need to put the plane in front of you and put the tab in front of you and run the propellers to a minimum; if you feel more wind left to increase the power of the right propeller and vice versa.
For the price really does not hesitate!
