Special Designed Helicopter with Auto Stabilizing System - Walkera 4F200 Tri-Blade Helicopter
4F200 is a very unique model, it features a special Tri-Blade Rotor and a Tri-Blade Tail Rotor which has very few competitors on the market, combining the Auto Stabilizing System (3-Axis Gyro), it performs amazingly stable! Furthermore, 4F200 is a Collective Pitch helicopter, which means all 3 main blades can change angle to generate more wind for quick moving, for Helicopters with this design, it will move much quicker than normal Fixed Pitch Helicopters, this is a very effective design as they use on real helicopters.
Why is there so few Multi-Blade Rotor Helicopters on the market?
Multi-Blade Rotor Helicopters are unstable, this is because they usually do not have the Flybar Rod on the rotor head to stabilize the heli body. Multi-Blade Rotor Head Helicopters require computer system constantly monitoring the body movements and compensate any erratic moves. Walkera factory has the experience in making 3-Axis Gyro, so they put it on this 4F200 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 RX2612V controller is amazing, it acts like a Co-Pilot to stabilize the helicopter.
