Product overview
The T-MOTOR HEP-S 28*9 is a one-piece straight propeller for heavy-lift multirotor drones used in mountainous hoisting, field transportation and emergency response operations. Its 28-inch (715.3mm) diameter and 9-inch (228.6mm) pitch support a common thrust range of 3.8~7.6kg at a common speed range of 2350~3300RPM. Average single blade weight is 74g. The recommended maximum speed is 5550RPM and recommended maximum thrust is 22kg; the limit speed is 6220RPM and limit thrust is 28kg.
Construction combines resin-based carbon fiber composite with a PMI foam core, an optimized layup and T1100-grade carbon fiber reinforcement in high-stress areas. The propeller has a glossy finish and a flange mount with a Ø10mm center hole, Ø20mm bolt circle and four Ø3mm mounting holes. Motor compatibility includes MN805S KV150, with 12S recommended voltage and a recommended quadcopter takeoff weight of 21kg. Recommended motor solutions are MN805-S KV150, MN801-S KV120 and U11 II KV120. An integrated molded QR code supports traceability, while protective packaging helps protect the propeller during transport.
