Flywing BO-105 ACE GPS-Stabilized 470-Size Scale RC Helicopter, 4-Blade Metal Head, M10 GPS, RTF/PNP (Not H1)

Overview

The Flywing BO-105 ACE is a scale RC Helicopter modeled after the MBB Bo 105, featuring a 470-size fuselage and ACE flight controller (not H1). The system integrates a built-in GPS module with an M10 multi-mode chip and barometric altitude assist for highly stable, GPS‑aided hovering and intuitive control. A four-blade all‑metal rotor head, coordinated-turn logic, and soft takeoff/landing provide realistic, scale-like flight behavior.

Key Features

• All‑metal CNC 4‑blade quick‑release rotor head; high‑efficiency nylon quick‑release blades.
• Custom NACA 8‑H‑12 flat convex prop design for improved low‑speed lift.
• ACE flight controller with built‑in GPS; M10 GPS positioning assist and barometric altitude assist.
• ATT Self‑leveling Mode for automatic attitude correction.
• Coordinated turn function for tighter, scale‑authentic banked turns.
• Soft takeoff/landing to reduce speed during launch and touchdown.
• Three adjustable flight modes: Soft, Standard, Sport.
• Multi‑layer safety: one‑key return‑to‑home (RTH) and low‑battery auto return.
• Transmitter supports compass calibration directly from the radio; LED status changes red → yellow → green.
• Flight controller auto‑detects battery voltage and prevents takeoff when not fully charged.
• Efficient power configuration with 16V brushless motor and tail‑mounted brushless motor; up to 22 min flight time.
• High‑performance metal gear servo: 4KG.CM torque, 0.12sec/60° response.
• High‑precision 10‑channel transmitter; approx. 1 kilometer control range; compatible with third‑party SBUS transmitters (9+ channels).
• Protective packaging with custom foam lining for safe transport.

Details

The Messerschmitt-Bölkow-Blohm Bo 105 is a light twin-engine, multi-role helicopter developed by Bölkow in Ottobrunn, West Germany. It was the world’s first light twin-engine helicopter and the first rotorcraft capable of aerobatic maneuvers, including inverted loops. Introduced in 1970, it featured a hingeless rotor system—a major innovation in helicopter design. This example is painted yellow with ADAC markings and registration D-HUHN, indicating its role in emergency or rescue operations. The aircraft showcases advanced engineering for its era, offering high performance, agility, and versatility in various operational roles.

The BO-105 features high-fidelity details, including enhanced rivet and panel line details. Neatly arranged panel lines and a realistic metal rotor head evoke memories of an iconic era.

New 4-blade rotor head with user-friendly QR propeller design, all-metal CNC construction, quick-release nylon blades, simplified installation.

Custom NACA 8-H-12 flat convex prop offers excellent low-speed performance and high lift. Thick cross-section enhances lift, enabling lower wing loading for improved takeoff and landing.

ACE flight controller, based on the H2 system, delivers smooth performance for FLYWING helicopters. It includes a built-in GPS module and M10 multi-mode chip for strong, stable signal reception and precise navigation. Integrated with FLYWING’s custom core systems, it ensures reliable, high-level flight control. The black unit features labels like "H-ACE SCALE" and "Powered by H2," along with ports marked S+, S-, LED, AUX, ESC, TAIL, L, R, B, and 5V. A red connector block is located on one side, providing secure connections. Compact and efficient, it’s designed for scale helicopter applications requiring accuracy and stability in flight operations.

Flight controller auto-detects battery voltage. If not fully charged, LED flashes red and yellow, preventing takeoff until a fully charged battery is installed.

BO-105 Ace RC Helicopter has M10 GPS and barometric assist for stable flight. Intuitive controls enable easy hovering and movement, ideal for relaxed flying in open spaces. (39 words)

ATT Self-leveling Mode uses gyro, accelerometer, and barometer for real-time attitude correction. Helicopter stabilizes autonomously when controls are released, offering easier handling than GPS mode with more hands-on flying experience.

Combining forward stick with rudder initiates a coordinated turn, with the flight controller measuring speed and applying precise roll. This ensures smooth fuselage banking, reduces turning radius, and maintains a realistic, scale-like attitude. The result is tighter, more aerobatic turns without additional input—simply push forward and yaw. A yellow ADAC helicopter is in flight against a clear sky, demonstrating the maneuver with authenticity and precision.

Soft takeoff/landing for realistic, graceful helicopter operation. ADAC marked yellow RC helicopter on helipad.

Three adjustable flight modes—soft, standard, and sport—allow instant switching via the transmitter without computer setup. Soft mode provides gentle flight, perfect for beginners. Standard mode boosts speed and tilt for more dynamic maneuvers. Sport mode maximizes responsiveness, speed, and angle for an intense flying experience. The yellow helicopter features ADAC branding and is captured in mid-flight against a clear sky, showcasing its agility in various positions.

Yellow BO-105 RC helicopter with ADAC branding hovers above a stylized globe marked by a location pin, highlighting navigation and safety features. It includes multi-layer protection with one-key return-to-home (RTH) and low-battery auto-return. In open areas, pressing RTH after takeoff triggers automatic return and precise landing at the departure point. When battery voltage hits the preset safety threshold—ensuring enough power for full return—the system automatically initiates RTH. These intelligent functions enhance flight security and operational reliability, making it ideal for outdoor use where signal loss or power depletion may occur. Designed for ease and safety, the model combines advanced technology with intuitive controls to support stable, worry-free flights in diverse conditions.

The transmitter supports compass calibration via the ACE flight controller. Toggle mode switch three times to enter calibration. Rotate helicopter while LED changes from red to yellow to green. System reboots automatically after calibration.
