NewBeeDrone LionBee Long Range ELRS2.4 AIO Flight Controller

The NewBeeDrone LionBee Long Range ELRS 2.4 AIO is engineered specifically for 1S micro long-range FPV—a true breakthrough in ultra-light endurance drone design. Built around a high-performance AT32F435 288MHz MCU, BMI270 gyro(started from Early March 2026), custom AM32 ESC, and the Smart-Max 800mW VTX, it delivers high efficiency, stable long-distance control, and excellent low-voltage performance—perfectly optimized for 18650-powered long-range missions. A custom 0.5mm high-current brass battery plate replaces unreliable spring contacts, ensuring clean, low-resistance power delivery even under heavy load. The extended 25.5 × 82mm AIO layout minimizes electrical noise, shortens high-current paths, and enhances overall flight stability. With full reverse-polarity protection, the LionBee AIO prevents damage and ensures that accidentally inserting the 18650 battery backward will not damage the FC, ESC, PA, or other electronic components—an essential safeguard for field operation. The redesigned modular replaceable battery chamber features factory-soldered brass terminals and allows quick replacement if damaged during impact. Package Includes: 1x LionBee Flight Controller 2x LionBee Battery Compartment 1x NewBeeDrone Honey Dipper 5.8G UFL Antenna (IPEX1) 1x BeeT-Antenna for ExpressLRS(ELRS) 2.4GHz receiver MHF3 1x LionBee GPS Adapter Cable (JST 1.0 to 0.8, 30mm) 1x Full Screw & Hardware Pack IMPORTANT NOTES: Always verify battery polarity before connecting USB power. Incorrect polarity may cause permanent hardware damage. When operating the VTX at MAX power levels, please ensure the VTX antenna is securely fastened before powering on. Operating at high output without a properly connected antenna may lead to permanent hardware damage or VTX burnout. Please note that the reverse polarity protection circuit does not function while also having USB plugged in.
