Perfect Balance of Strength and Weight

Tough, Agile, Built for Impact

Patented Impact-Resistant Frame Design

Featuring a hollowed, rib-reinforced structure and a 2.5 millimeters herringbone carbon plate design, it achieves a precise balance of rigidity and toughness. The frame’s five front-facing stress points are reinforced with 8 layers of ABS armor, strengthening impact-resistant areas. Every collision is a confident response to the limits of its structure.

PE+PC Composite Eco-Friendly Material

Combining lightness and toughness, with reinforced thickness. Tested over four generations and hundreds of material trials, it maintains the integrity of the body even under intense collisions, easily withstanding high-frequency impacts and always staying battle-ready. Made from eco-friendly, heat-resistant, and insulating materials, ensuring safety and peace of mind for children.

High-Speed Altitude-Hold Flight Control Algorithm

Intelligence that Balances Speed and Stability

High-Speed Altitude-Hold Algorithm

With over a decade of Radiolink’s expertise in high-speed autonomous flight control development, this algorithm perfectly resolves the contradiction between velocity and stability. It ensures that in altitude-hold mode, the throttle delivers stabilization-level response speed. While the flight controller assists with stabilization, the drone flies faster, enabling beginners to compete with greater accuracy.

Flight Control Tuning Capability

With over a decade of experience in flight controller operation, the parameters can be finely tuned to achieve optimal flight performance. Combined with a high-dynamic attitude algorithm, the LDZ-B20 maintains precise attitude control even during high-speed maneuvers. It can brake sharply and stop instantly at full speed, and after repeated intense collisions, it remains stable without erratic movements—ready to return to competition mode immediately.

Five Operating Modes

Altitude Hold (Low-Speed), Altitude Hold (High-Speed), Stabilize Mode, Turtle Mode, and Air Mode — five operating modes can be easily switched with one click.

When the drone ball flips over, Turtle Mode can be activated to quickly right itself.

Stabilize Mode empowers Strikers to make lightning-fast attacks and score; Altitude Hold Mode enables Keepers to defend with rock-solid stability, earning the title of Best Goalkeeper.

Multiple modes allow for flexible tactical expansion and effortless control of the field.

Excellent Anti-Interference Communication Capability

Unlike open-source systems where frequency bands easily overlap—often causing signal interference in multi-player competitions—Radiolink employs a proprietary pseudo-random frequency hopping technology combined with its proven wireless communication algorithm, refined over 22 years of development. This ensures interference-free operation even when more than a hundred users can compete at the same venue without interference, giving a decisive advantage in drone soccer team matches.

SZ-SPEED 1505-3150KV Brushless Motor

Manufactured with aerospace-grade machining precision, each motor undergoes high-accuracy dynamic balance calibration. It delivers exceptional current tolerance and instantaneous burst power, ensuring rapid yet stable power output — easily handling high-intensity flight conditions with confidence.

HQProp T3*3*3 3-Inch Propellers

Custom-designed for drone soccer, these propellers feature a precisely optimized pitch ratio that balances thrust and responsiveness. They maintain excellent stability and low noise during high-speed rotation, enabling the drone soccer to achieve faster response and smoother attitude control—combining speed with elegance as it cuts through the air.

Gensace 4S 850mAh 40C LiPo Battery

Delivers exceptional high-discharge performance and powerful burst output. Built with premium cells that support over a thousand charge cycles while remaining stable and reliable, it easily withstands the demands of high-frequency, competition-level missions.

Intelligent Charging System

Dual Guarantee of Efficiency and Safety

Gensace Charger B6

The standard configuration includes a Gensace 60W 5A 2–4S engine battery charger, which intelligently detects battery status and dynamically adjusts charging current and voltage to ensure an efficient and safe charging experience while extending battery lifespan.

RadioLink Charger CM210

Also included a Radiolink 2S transmitter battery dedicated charger — lightweight, efficient, and highly compatible — providing a fast charging solution that keeps your transmitter fully powered and ready at all times.

RadioLink Charger CB86-PLUS

It also supports 1–6S multi-type battery balance charging, featuring a built-in high-precision voltage detection and balancing algorithm for precise control of each cell, ensuring energy safety (optional, expandable accessory).

High Cost-Performance

A Confident Expression of Domestic Innovation

All core electronic components of the flight controller, ESC, and remote control system are independently developed, achieving an optimal balance between performance and cost.

Standardized components and easy maintenance make training and competitions more efficient and economical.

The remote control and charger are compatible with multiple aircraft, reducing consumption and increasing efficiency, while lowering the cost of upgrading equipment.

Intelligent Low-Voltage Protection

The main interface of the remote control allows real-time monitoring of the drone ball's battery voltage. When the voltage drops below 14.7V, the remote emits a beeping alarm to prompt a timely landing and battery replacement. If the voltage reaches 14V, the drone will automatically land to prevent over-discharge, protecting battery life and extending its competitive performance.

Colorful RGB Light Strip

An integrated, detachable 7-color (red, green, blue, yellow, purple, cyan, white) RGB LED strip (16 LEDs) plus tail light, supporting custom programmable effects for easy role switching.

Complies with the technical requirements of multiple competitions, including the FAI World Drone Soccer Championships(F9A-B), Volume F9 Drone Sports(F9A-B Provisional class), and U.S. Drone Soccer(20cm Drone Soccer Gameplay).
