Red 250 mm Wheelbase FPV RED BEE Racing Drone / Quadcopter FPV
A FPV racing quadcopter system which includes a light weight 250mm quadcopter and a high sensitive remote controller with a mounted LCD display to realize a long endurance thrilled FPV racing. A uniquely designed 2S 2500mAh Li-ion 18650 smart battery sets it apart from other commonly used batteries today (a comparison table between Li-ion and Li-po batteries is attached). The battery stands out with its long endurance, stability, safety, and lightweight. With powerful thrust provided by two batteries, the quadcopter can fly 13-15 min. Additionally, the batteries can be switched between the quadcopter and the remote controller, resulting in another 13-15 min fly. Normally with only 4 batteries, the quadcopter can fly 26-30 min. This long endurance capability is hardly seen with any other similar 250mm drones.
A modular design makes LY-250 easily build, rebuild, repair, and maintain. The quadcopter has only 28 screws and can be disassembled in 5 min. Its all major parts are plug-in assembled to allow easy upgrade and add more modules such as a sports camera onto the flight control board and system itself. Each part of LY-250 has been well designed and tested for the lowest weight, the longest endurance, and the best performance. Its high-resistant plastic frame assures the quadcopter to pass more than 10,000 drop tests.
Its propellers are small but 100% balanced tests ensure that they hardly break themselves. A 7-channel LY-I6 transmitter assures the 1024 class sensitive control under three flight modes: Self-stabilization Mode, 3D Flight Mode, and Full Manual Mode. Under Self-stabilization mode and trainer mode, the quadcopter can be started by an amateur, which is also a challenge to a professional aircraft modeller to master it under Full Manual Mode. 6-axle Gyro Specifications.
