Tri-Blade Rotor Head + Tail Rotor - Just like a real life 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
3D Flying Ready - Able to store Pitch Curves and Throttle Curves for 3D Aerobatics
Very Compact Size - Only 42cm long, no longer than your Keybroad
Flybarless Design, simplify mechanism - A clever design, easier to repair
Aluminum CNC Parts - Durable and Precise, important for any players
Truly a CCPM 3D Helicopter - Three CCPM Servos + Rudder Servo and Brushless Motor
Perfect Combination - Belt Driven Tri-Blade Tail Rotor, built for performance
Note: These helicopters are not for beginners. They are only recommended for
adult, or experienced R C Pilots.
Simulated three-blade structure takes advantage of high efficiency and steady flight.
3-axis controlled balance system provides accurate flight location.
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.
