F03 RC Helicopter 4CH Flybarless Altitude Hold Helicopter With 6 Axis Gyro RC Helicopter RC Toy Gift For Beginners Adults | RC Helicopters Features: * Features: 2.4GHz 4CH (UP/down;forward/backward; left/right turn; left/right side flight); one key take-off/landing; 6-axis gyro; altitude hold. * SIX AXIS GYRO & INTELLIGENT AIR PRESSURE FIXED HEIGHT: Built-in 6-axis gyro makes the flight more stable and precise, especially suitable for beginners to fly. Use air pressure module with fixed height, integrated algorithm, limit climb, sink rate, make beginners master quickly, reduce the probability of the plane being damaged to a very high extent. * HIGH-INTENSITY COMPOSITE TECHNICAL MATERIAL: Undercarriage and mainframe use PA66+GF (nylon and fiberglass) composite, has high intensity, high toughness, no deformation, resistance to collision, ensures flight accuracy and durable use. * HIGH-EFFICIENCY STRONG MAGNET ELECTRIC MACHINE: Use 050 strong magnet core motor and specially made 8520 coreless motor, strong dynamic power, more energy-saving, stable and sensitive than average motor. * FLYING IN ALL DIRECTIONS: Use high-efficiency 4.3g digital rudder control, high torque fast-reacting, inaccurate back characteristic, response speed 60°/0.05ms. * FLYBARLESS DESIGN: Adopt flybarless design, cancel the traditional balancing bar structure, electronic stabilization system, hand feeling is more accurate, the flight is more stable, optimize the structure and reduce the probability of damage. AIR DYNAMIC DESIGN: The propeller uses air dynamic design, offers strong power and body stability. Has high efficiency, power, can fly longer. The blade uses nylon and carbon fiber, with high intensity, high toughness, resistance to collision. * 3.7V 700mAh 20C lipo battery, high discharge rate, provides 15-20 minutes of use time, longer duration of flight, making it more exciting. The 2.4GHz communication protocol can expand the satellite receiver to support DSMX DSM2 PPM SBUS systems.
