Product overview
The RadioLink LD-B22 is a 200mm brushless drone soccer aircraft for training and competition, including F9A-B, F9A-B provisional-class events and U.S. 20cm gameplay. Its propellers sit within a fully enclosed protective frame. The structure combines hollowed, rib-reinforced construction with a 2.5 millimeters herringbone carbon plate design and modified polypropylene material. Five front-facing stress points carry eight layers of ABS armor. For venue planning, the recommended competition cage for 200mm aircraft measures 6 × 3 × 3 meters.
The aircraft integrates a RadioLink APM flight controller, a 40A 4-in-1 ESC stack, SZ-SPEED 1507-4000KV brushless motors and Gemfan 2.8-inch (2828) propellers. Its Gensace 4S 850mAh 40C LiPo battery accompanies a takeoff weight of 298g. Flight time is 5–6 minutes and control distance is 3000 meters, with flight data measured in a good flight environment. Adjustable control parameters support tuning, while the default Stabilize and Turtle modes provide stabilization and self-righting after inversion. Communication uses proprietary pseudo-random frequency hopping.
The supplied flight platform package contains the blue/red LD-B22, T12D transmitter, flight battery, Gensace B6 charger, package bag, cables, hex wrench and spare hook and spring. The standard charger supports 2–4S batteries at 60W and 5A; CM210 and CB86-PLUS chargers are optional accessories. The transmitter displays aircraft battery voltage and sounds an alarm below 14.7V, prompting landing and battery replacement. At 14V, the aircraft lands automatically to prevent over-discharge. A detachable 16-LED, seven-color RGB strip and tail light support programmable lighting effects.
