With its short nose, tight frame, and balanced structure, the FL500 BO105 is built for those who value control and responsiveness. It’s a great choice for open-field flying, offering a satisfying combination of scale realism and maneuverable handling. What sets the BO105 apart is its integrated cockpit, adding a deeper level of visual authenticity.
- FL500 UH-1 Huey: Nostalgia with Modern Flight Confidence
Built with scale authenticity in mind, the FL500 UH-1 Huey captures the timeless look of classic rotorcraft with its rounded front, twin-blade configuration, and tall tail boom. It’s a model that brings historical character into the present—with solid structural balance and smooth hovering performance. Whether you're drawn to military aesthetics or simply enjoy flying something with heritage, the Huey offers a visually striking and reliable flight experience.
