Product overview
The T-MOTOR HEP-L 20*7 is a one-piece straight propeller for long-endurance multirotor UAVs. Its 20-inch (511.6mm) diameter and 7-inch (177.8mm) pitch support a common thrust range of 1.0~2.1kg at a common speed range of 2700~3700RPM. Aerodynamic optimization improves hovering efficiency and increases effective flight time by up to 3%. The enhanced propeller structure reduces vibration and improves wind resistance during cruise. Recommended maximum speed is 6950RPM, with a limit speed of 7800RPM; recommended maximum thrust is 9kg, with a limit thrust of 11kg.
Built from resin-based carbon fiber composite with a PMI foam core, the HEP-L 20*7 has a matte finish and an average single blade weight of 27g. High-toughness resin, surface fiber reinforcement and a damage-tolerant design limit micro-damage propagation. Its flange mount uses a Ø6mm center hole, Ø12mm bolt circle and two Ø3mm mounting holes. The recommended MN501 KV300 combination uses 6S voltage and a 6kg quadcopter takeoff weight. An integrated molded QR code supports lifetime traceability, while protective packaging helps protect the propeller during transport.
