JJRC Little Bird Remote Control Helicopter U9901 Remote Control Armed Simulation Flight Model Aircraft Optical Flow Positioning

1: 6-channel aileron free design, utilizing aerodynamic principles to design propellers that provide strong power and self stabilization of the aircraft, resulting in ultra stable flight; 2: The main seat remote control has a more precise control feel, and the digital servo is more durable; 3: Brushless direct drive motor, with stronger power, more sensitive response, and good wind resistance. 4: Barometer altitude setting, optical flow hovering, stable flight; 5: High rate modular rechargeable battery, power indicator, easy and fast installation, effectively protects the battery, and has a longer service life; 6: Ascending, descending, advancing, retreating, flying on the left side, flying on the right side, rotating on the left side, rotating on the right side, and flying along the flight path; 7: One click takeoff. One click landing. One click rewind. 8: Using a 6-axis gyroscope for stable flight, especially suitable for beginners to fly; 9: Low voltage alarm, locked rotor protection, loss of control protection, large and small rudder conversion, 10: Equipped with a dedicated USB charger, charging is fast, safe, and stable; New features: One click controllable automatic route, one click controllable automatic turning point, forward 360 degree roll.
