Product Description:
1. 470-scale BO105 realistic helicopter simulation with six-channel RC control. Equipped with a 16V high-power motor for easy maintenance. Features an ACE flight controller with omnidirectional positioning technology and BeiDou positioning system for precise hovering. Intelligent return-to-home functionality automatically guides the aircraft back to takeoff point during low battery or loss of visual contact. After GPS acquisition, switch to GPS mode anytime during 3D aerobatics to recover the aircraft.
2. BO105 defaults to coordinated turning. When turning with the directional joystick (left stick for US-style controls), the flight controller automatically increases aileron roll control based on current airspeed. This enables tighter turns with more realistic and elegant turning posture.
3. Equipped with 3508-class high-torque brushless motors driven by 16V power, delivering greater horsepower and efficiency. Paired with a 32-bit dual-processor 16V 60A full-metal helicopter-specific ESC, the helicopter maintains ultra-responsive handling during intense 3D maneuvers. Superior constant-speed performance ensures consistent power output throughout flight, preventing spin-outs.
4. The ACE Smart Simulation Helicopter utilizes a custom 2.4G transmitter, achieving a maximum 1KM communication range in interference-free, unobstructed environments. Should signal loss occur beyond this distance, the helicopter autonomously initiates return-to-home (RTH). During RTH, the return function can be canceled by switching the RTH switch to manually regain control. During takeoff and landing, the flight controller fully manages vertical speed. Once altitude reaches 1 meter, control switches to proportional throttle via the transmitter. This feature prevents excessive takeoff speed. Throughout takeoff, all joystick functions remain unaffected except the throttle stick. (Note: Ground clearance estimation relies on barometric pressure, which may introduce slight inaccuracies in windy conditions.)
5. Utilizes a 4S 5000mAh battery paired with a 16V Gold Power Kit (3508+60A helicopter-specific metal-cased ESC), significantly boosting efficiency. Enjoy over 20 minutes of extended flight time for uninterrupted enjoyment (PNP version excludes battery and transmitter).
6. Three-stage sensitivity modes: The helicopter features three built-in flight sensitivity settings, switchable via transmitter toggle.
Gentle Mode: Maximum flight speed, maximum flight angle, and response speed are restricted. Ideal for beginners to master helicopter operation.
Standard Mode: Maximum flight speed, maximum flight angle, and response speed are faster than Gentle Mode. Suitable for everyday flying.
In Sport Mode, the helicopter's maximum flight speed, maximum flight angle, and response speed reach the maximum values set by the flight controller. The helicopter becomes highly agile and flies at high speeds. This mode is recommended for experienced pilots in open areas.

Important Notes: RC model helicopters are high-risk products. Always fly away from crowds. Improper assembly, unfamiliar operation, damaged components, faulty electronic controls, or lack of familiarity with controls may lead to unpredictable accidents such as loss of control or injury. Pilots must prioritize flight safety and understand they bear full responsibility for any accidents resulting from negligence. Before each flight, meticulously inspect the main rotor hub cross-shaft screw, tail rotor hub screw, and all ball joints and screws throughout the airframe. Ensure all fasteners are securely glued and tightened before taking flight.
