Product overview
The NF-CY250 is a racing UAV training set built around an X-configuration frame made from carbon fiber and metal. Its wheelbase is at least 114 mm, with upper and lower base plates at least 2.0 mm and 3.5 mm thick respectively. Empty aircraft weight is specified as no greater than 174 ±10 g. The equipment configuration includes a flight controller, camera and remote controller, making this an assembled aircraft training set rather than an airframe-only kit.
The flight controller combines an STM32F411 processor, MPU6000 gyroscope, electronic compass, Micro-USB interface and at least 8 MB of storage. Its external dimensions are at least 30.5 × 30.5 mm. The camera provides CVBS video with NTSC/PAL options and a 16:9 image. Electrical integration must account for the controller’s 2–4S input and the camera’s DC 3.3–6 V input. All components, including propellers, arrive assembled with common control parameters configured; flight preparation requires fitting fully charged batteries to both the transmitter and aircraft.
