High-Speed Altitude-Holding Flight Control Algorithm

The Optimal Solution for Speed and Stability

Stable Altitude-Holding at High-Speeds

With over ten years of experience in the research and development and use of high-speed autonomous flight control, Radiolink’s attitude algorithm under high dynamic conditions, combined with flight control parameters tuned to the optimal flight state, perfectly resolves the contradiction between high speed and stability. This ensures that the throttle response speed in altitude-holding mode is the same as that in self-stabilizing mode. Simultaneously, the LD-B20C maintains precise attitude control even under high-speed dynamic flight conditions, and can brake sharply and stop instantly at full speed. Even after sustained and violent impacts, it will not fly erratically and will immediately switch back to racing mode.

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 five 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.

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 23 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.

Three Operating Modes

Altitude Hold Mode, Stabilize Mode, and Turtle Mode — three 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.

SZ-SPEED 1404-4600KV 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 2.5-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 3S 680mAh 30CLiPo 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.

2.4GHz Excellent Anti-Interference Remote Controller

FHSS spread spectrum algorithm + 67-channel pseudo-random sequence frequency hopping to achieve superior anti-interference ability to both the same frequency band and different frequency bands, a unique ID identification code blocks crosstalk interference sources, achieving double isolation from crosstalk interference.

T8S: 8-channel remote controller (optional)

A gamepad remote controller with the same functions as the T12D, more suitable for younger players.

T12D: 12-channel remote controller (optional)

Can be connected to an external training cable, supporting simultaneous training for two players.

Intelligent Low-Voltage Protection

The main interface of the remote control(T16D) allows real-time monitoring of the drone ball's battery voltage. When the voltage drops below 11.1V, the remote emits a beeping alarm to prompt a timely landing and battery replacement. If the voltage reaches 9.9V, the drone will automatically land to prevent over-discharge, protecting battery life and extending its competitive performance.

The interior of the case is lined with thick, high-density foam padding to protect the drone soccer from damage caused by drops from height or long-distance transportation.

The side of the backpack features a name tag slot, allowing participating students to fill in their name, class, and contact information, helping prevent taking the wrong or losing competition equipment.

Dustproof and waterproof, this portable backpack is easy to carry by hand or wear cross-body. Whether for training or competitions, the entire set of equipment is ready to go.

All accessories have designated slots to prevent students from forgetting any spare competition parts.

High-Performance, Cost-effective

Universal accessories and convenient maintenance, with universal remote controllers and chargers for multiple aircraft, significantly reduce long-term investment costs for training and competitions.

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).

Comprehensive Safety Protection

Unlike traditional racing drones with exposed propellers, the drone soccer aircraft features a fully enclosed protective frame made of high-toughness materials. The 360° shielding design eliminates propeller risks, ensuring zero injury during training and competition.

Venue-Friendly Design

Unlike fixed-wing or FPV drones, which require large open spaces, the international drone soccer arena only needs an area of 14x7x5 meters(Recommended competition cage size for 200mm drone soccer aircraft: 6 × 3 × 3 meters). Even a corner of a school campus can be transformed into a competitive arena.

Multi-Dimensional Empowerment

It sharpens hand-eye coordination, stimulates creative thinking, enhances focus and reflexes, and fosters leadership qualities through teamwork.

Comprehensive Competition Ecosystem

Fully compatible with 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)", creating a clear competitive pathway from campus to international levels.
