Product overview
The T-MOTOR HEP-L 21*7 is a one-piece straight propeller for long-endurance multirotor UAVs. Its 21-inch (537.4mm) diameter and 7-inch (177.8mm) pitch are paired with an average single blade weight of 32g. Construction combines a resin-based carbon fiber composite with a PMI foam core and a matte finish. High-toughness resin, surface fiber reinforcement and a damage-tolerant design help limit micro-damage propagation, while an integrated molded QR code supports traceability. Protective packaging helps safeguard the propeller during transport.
The flange mount has a Ø6mm center hole, a Ø12mm bolt circle and two Ø3mm mounting holes. Recommended combinations are MN6007 II KV160 + FLAME 60A at 12S and MN6007 II KV320 + FLAME 60A at 6S. With either corresponding motor and voltage configuration, the recommended quadcopter takeoff weight is 7kg. Recommended maximum speed is 6800 RPM and recommended maximum thrust is 10kg, with limits of 7650 RPM and 13kg respectively.
