Product overview
The RadioLink LD-B22 is a 200mm brushless flight platform for drone soccer training and competition. Its fully enclosed protective frame surrounds the propellers, combining modified polypropylene with a hollowed, rib-reinforced structure and a 2.5mm herringbone carbon plate. Five front-facing stress points receive eight layers of ABS reinforcement. Stabilize Mode assists flight control, while Turtle Mode enables self-righting after a flip. Adjustable flight control parameters allow its response to be tuned. For venue planning, the recommended competition cage for 200mm aircraft measures 6 × 3 × 3 meters; international arena dimensions are 14 × 7 × 5 meters.
The installed propulsion and control equipment comprises a RadioLink APM flight controller, integrated 40A 4-in-1 ESC, SZ-SPEED 1507-4000KV brushless motors and Gemfan 2.8-inch (2828) propellers. Power comes from a Gensace 4S 850mAh 40C LiPo battery. Flight data measured in a good flight environment give a 298g takeoff weight, 5–6 minutes of flight time and 3000 meters of control distance. 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.
The supplied package contains one blue/red LD-B22 aircraft, T12D transmitter, flight battery and Gensace B6 charger. Accessories include a Type-C upgrade cable, 1.5mm hex wrench, spare hook and spring, ELRS receiver connection cable, adapter cable for an 18650 lithium battery case, and package bag. The standard charger is rated at 60W and 5A for 2–4S batteries. Optional charging equipment comprises the CM210 for 2S transmitter batteries and CB86-PLUS for 1–6S balance charging. A detachable RGB strip provides 16 LEDs in seven colors, accompanied by a tail light and programmable effects.
