I love this helicopter is stable, maneuverable, easy to use and very solid (very resistant to crashes), good quality, for cons, it is best used indoors because it deviates very fast with the wind. Note some small flaws, such as son who are stuck in the screws of the remote control, and can be cut, as if the helicopter does not respond to commands, or it does not work well, unscrew the remote control and check if the welds are welded, it happened to me. This helicopter is very beautiful, very small and I would recommend it and easily repairable!
