The body is made in EPP material. It's lightweight and has a smooth surface. Compared with other materials, it's flexible and anti-crash. Three wheels of the plane are made in EVA material, which is durable.Driven by multiple air cylinders, the propeller generates an upward airflow. The route lock is more stable.This scale model supports the adjustment of the lifting angle. Besides, this model applies the three-channel design, which is rarely seen in the market.The three-channel remote controller increases the control distance up to about 200 meters, which supports a farther flying distance.The remote controller makes distinctions between small and large rudder. The small one is suitable for beginners. With the controller in the large rudder state, if you keep moving the joystick up and down, the aircraft will make a head rotation.
