NewBeeDrone LionBee 3" LR DIY Drone Developer Kit - ELRS 2.4GHz

Help build the future of drone design with the NewBeeDrone LionBee 3" Long Range DIY Developer Kit. The LionBee reimagines 1S FPV drone design with an innovative flight controller integrated directly into the battery structure, improving durability, efficiency, and vibration resistance. Built with an advanced AT32F435 processor, a next-generation ESC, and an 800mW Smart-Max VTX with adaptive output, it offers reliable performance for demanding flights. Designed as a modular developer platform, the LionBee is ideal for pilots and innovators looking to experiment and push the boundaries of micro long-range FPV. NOTE: This is a DIY kit. Assembly is required. Check out our other pre-built quads, and the rest of our NewBeeDrone products.
