LJI X4 500 13"

LJI X4 500 is a frame with a motor diagonal distance of 500mm designed for 10–13" propellers. The frame is suitable for building a test platform with ArduPilot firmware, which offers ample space for mounting sensors and additional payload. The frame is not suitable for building a classic freestyle FPV quadcopter.

The frame is made of a combination of carbon plates and tubes. Motors are mounted on carbon holders at the ends of the arms. The frame can be built in both X4 and X8 configurations for greater thrust. The center plates provide enough space for mounting a flight controller, power supply, and other electronics. On the underside of the drone, there are two fiberglass tubes that serve as a universal platform for mounting any payload.

The bottom plate has standard mounting holes of 30.5×30.5mm for easy attachment of a flight controller used in FPV drones. The motor mounting holes are 16–19mm M3. The total weight of the frame is approximately 480g.

LJI X4 500 is suitable for pilots looking for a simple and versatile frame for building a mid-sized quadcopter with a focus on stable flight.
