Features, Architecture & Package Contents

WLToys AS350 2.4G 4CH RTF Micro RC Helicopter Model Optical Flow K150 Air Rescue

Features:

.AS350 Scale-Inspired Three-Blade Flybarless Structure: Scaled down from the AS350 helicopter, this model features a refined exterior design and a three-blade flybarless rotor configuration, emphasizing realistic proportions and mechanical layout.
.Aerodynamic Rotor Design with Stable Flight Characteristics: Rotor blades are designed based on aerodynamic principles to generate strong lift while supporting natural self-stabilization during hovering and directional movement.
.Brushless Power System with High-Rate Battery: Equipped with an 1106 brushless outrunner motor and a 3.7V 500mAh 25C battery, the power system delivers responsive output and consistent performance. A dedicated USB charger is included to help manage charging protection.
.4-Channel Control System with 6-Axis Gyro and Altitude Hold: The helicopter uses a simplified 4-channel layout combined with a 6-axis gyroscope and barometric altitude hold. Supported functions include one-key takeoff and landing, vertical ascent and descent, forward and backward movement, left and right rotation, and lateral flight. The transmitter also supports dual rate switching, hover midpoint setting, and low-voltage alert.
.Precision Control and Signal-Loss Protection: The transmitter features independent gimbal positioning for improved centering accuracy and refined control feel. High-efficiency 2G digital servos provide fast response and precise return-to-center behavior. In the event of signal loss, the aircraft maintains its current altitude for approximately two seconds before performing a controlled descent, allowing reconnection if the signal is restored in time.
