Perfect Balance of Strength and Weight
Strong and Resilient, Crash- and Impact-Resistant
Patented Impact-Resistant Frame Design
Featuring a hollow reinforced structure and 5 millimeters ⊗-shaped carbon plate design, it achieves an ideal balance of rigidity and toughness. The five major frontal stress points are reinforced with 8x-strength ABS armor, fortifying high-impact areas. Every collision is a confident response to the limits of structural endurance.
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.
Four Operating Modes
Altitude Hold, Stabilize Mode, Turtle Mode, and Air Mode — four operating modes can be easily switched with one click.
When the drone ball flips over, Turtle Mode can be activated to right itself quickly.
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 2207.5-1950KV 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.
Gemfan 5-Inch(51466) 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 6S 1400mAh 150C 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
HOTA Charger T6
The standard configuration includes a HOTA DC/PD dual-channel smart charger T6.
With a maximum power of 300W, 15A charging current, and 94% operating efficiency, work more efficiently!
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).
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 22.0V, the remote emits a beeping alarm to prompt a timely landing and battery replacement. If the voltage reaches 21.5V, 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 (40 LEDs) plus tail light, supporting custom programmable effects for easy role switching.
