Product overview
The QJ-P4130 from Chengdu Qingjun Technology Co. is designed for power line stringing, including operations in mountainous areas and canyons. Its umbrella-style folding design reduces its folded volume to within 40% of its unfolded volume, making it more compact for transport and field deployment. Metal locking joints and a high-strength engineering plastic fuselage provide rigidity when unfolded and help withstand wind disturbance loads during stringing operations. Its working dimensions are 1740 × 1740 × 615 mm.
The aircraft combines a Q8P propulsion system with 32-inch folding propellers and high-torque motors. With this configuration, propulsion redundancy supports a safe forced landing following a single-axis failure. The large propellers and matched motors deliver a stated hovering precision of ±0.5 m, supporting professional line stringing in the complex wind environments encountered in mountains and canyons.
