Style: Helicopter with 2 Battery Model: C138 Overview The C138 is a readytofly hobby helicopter engineered for stable, controllable flight and easy battery management. Its aerodynamic propeller design and advanced flight systems reduce pilot workload, making it suitable for beginners and experienced users who want reliable performance for practice, photos, and flying maneuvers. Key benefits Ultrastable flight: A 6axis gyro system and aerodynamically designed propellers deliver steady, predictable handling that reduces drift and makes smooth maneuvers easier to execute. Precise control: A 6CH transmitter layout combined with three digital servos provides responsive, accurate control for both basic flying and more advanced stunt work. Consistent altitude: Barometerbased altitude hold maintains a steady hover without constant throttle input, useful for composing aerial photos or focusing on flight maneuvers. Convenient power management: The modular battery system supports quick installation and swap, while the intelligent power management extends battery life and protects cells during use. Fast, stable charging: A dedicated USB charger is included for reliable and convenient recharging of the included batteries. Features and performance Flight stability: 6axis gyro for automatic stabilization; propellers shaped by aerodynamic principles to improve lift and efficiency. Control system: 6channel control with three digital servos for precise pitch, yaw, and throttle response. Altitude hold: Barometer sensor maintains target altitude for smoother hovering and easier image capture. Battery system: Modular design includes two batteries for longer overall flight time and quick replacement between flights. Charging: Dedicated USB charger provides stable current for faster, consistent charging. How this product solves common problems Reduces crash risk by automatically stabilizing the helicopter during flight, helping pilots learn faster and reducing costs. Removes the need to constantly adjust throttle to maintain height thanks to altitude hold, improving the quality of aerial photos and steady flight sessions. Minimizes downtime with a modular twobattery setup and straightforward USB charging, so users can get back in the air sooner. Improves control precision for practicing maneuvers or performing light stunts without requiring complex setup. Practical use scenarios Aerial photography practice: Use the barometer altitude hold to keep the helicopter steady while composing and taking photos from low altitudes. Training and skill building: pilots can rely on the 6axis gyro and digital servos to learn hovering, turning, and basic aerobatics with fewer setbacks. Recreational flying and stunts: Intermediate users can exploit the responsive 6CH control and servo accuracy to practice rolls, flips, and tight turns in controlled environments.
