It is a ultra detailed micro helicopter. This hely has the safe feature. So if you are in panic when you are controlling your apache, the Safe can be activated and the hely goes in hovering with no additional commands from pilot.
The battery is a 2s 400mha lipo for about 5 minutes of flight. All brushless motors for main rotor anf tail. It is the BNF version so i used my old PCM10 with spektrum module.
