Here comes the Walkera 4F200LM 6CH 2.4GHz Helicopter. Inspired by the real helicopter Lama 315B, 4F200LM looks real. Also, it's tri-blade structure makes it a special one in the RC market. It is equipped with the latest technology– the 3-Axis Gyro with Auto Stabilizing Technology (AST), and by the meaning of 3-Axis Gyro, it acts like a Co-Pilot for the helicopter, it helps you to keep the helicopter's stability, isn't it amazing? What exactly a 3-Axis Gyro do? 3-Axis Gyro means it can sense X, Y and Z axis moments, that means body leaning forward / backward, body rolling left / right, tail drifting CW / CWW, it will constantly monitoring any off-balance in all directions, then it will give signals to all CCPM servos and Rudder servo to balance the helicopter, it works constantly and unless you have the helicopter drifts too much, you will not even notice the system exists. The following diagram will simply tell you more on how it works. What is flybarless system? Paddles are doubtless an important component in RC helicopters for a long time, it the aircraft stable. Recently, 3-Axis Gyroscope has been introduced to RC helicopters and this is how Flybarless System has born. The NEW Flybarless System takes away the paddles and flybar, leaving the stabilizing job completely to the high tech 3D Gyroscope. Proven by Helicopter World Champion, result is 100% positive. Without the weight of the flybar and paddles, the helicopter now moves in higher speed, and saves almost 30% energy. Also, less parts means less repair and maintenance! 3-Axis Gyro works with the flybarless system, this technology helps Walkera to produce such multi-blade helicopter. As multi-blade helicopters usually don't have a flybar to balance, the 3 axis gyro covers this and the technology monitors the helicopter movement. It is well applied on the 4F200LM, and made this 3-Blade Rotor Helicopter possible to fly, and not even "just fly around", but able to perform 3D aerobatic movements. The on-broad all in one controller is amazing, it acts like a Co-Pilot to stabilize the helicopter. Highlight features Simulated three-blade structure takes advantage of high efficiency and steady flight. 3-axis controlled balance system provides accurate flight location. High performance brushless motor absolutely features both longevity and power. 2.4G Frequency-Hopping Spread Spectrum technology automatically assigns ID code with strong anti-jamming and high accuracy. The CNC-machined three-blade main rotor structure is composed of metal blade holder, metal rotor head and metal swashplate Three-blade tail rotor structure with CNC-machined technology Carbon fiber blades feature outstanding roughness and rigidity, which are suitable for aerobatic flight performance 3900KV brushless motor offers highly efficient power drive RX-2618V receiver integrates together receiving circuit and flybarless control system. Highlight features of the WK-2801Pro The WK-2801 adopts 2.4Gig spectrum technology and features automatic code pairing and ID assignment LCD display of the WK-2801 is simple to understand and easy to set The transmitter case is ergonomically designed and the large LCD display has white backlight with easy-to-read graphics The length or tension of the controls stick can be adjusted and it is convenient to change the throttle from left to right The WK-2801 supports both helicopters and airplanes.
