Product overview
Designed for heavy-lift multirotor drones, the T-MOTOR HEP-S 34*11.5 serves applications including mountainous hoisting, field transportation and emergency response operations. Its one-piece straight construction combines a resin-based carbon fiber composite with a PMI foam core and a glossy finish. An optimized layup incorporates T1100-grade carbon fiber reinforcement in high-stress areas. The propeller measures 34 inches (868.1mm) in diameter with an 11.5-inch (292.1mm) pitch, and its average single blade weight is 117 g. Its aerodynamic geometry includes optimized airfoil, chord and twist distribution.
The common speed range is 2480~3150 RPM, and the common thrust range is 8.2~13.7 kg. Recommended maxima are 4420 RPM and 35 kg thrust, with limits of 4940 RPM and 44 kg thrust. Flange mounting uses a Ø10mm center hole and Ø23mm and Ø31mm bolt circles, each with four Ø4mm mounting holes. Recommended motors are A10 KV120, MN1010 KV90, MN1015 KV70 and MN1018 KV72. For a quadcopter with MN1018 KV72 motors and the recommended 24S voltage, recommended takeoff weight is 42.4kg. An integrated molded QR code supports traceability, and protective packaging provides transport protection.
