The coaxial-rotor design, built-in gyro and negative rotation of rotors of the MJX F29 are used to increase the helicopter's stability and operability. The aluminum fuselage and innovative design make the helicopters appearance attractive. Multiple helicopters can be flown simultaneously with high stability due to the 2.4Ghz auto connection technology. The Microcomputer control LCD remote controller brings more operational interest to the flight. You can randomly regulate the helicopter's left/right turning speed, left/right sideward flight speed and the speed of moving forward /backward by adjusting the parameters. Forward/backward and sideward flight are controlled by the swashplate. The helicopter is strong enough for outdoor free flight and is equipped with screw servo.
