Product overview

The T-MOTOR VZ20*8.2 is a one-piece straight propeller for VTOL compound-wing UAVs operating in multirotor mode. Its 20-inch (508 mm) diameter and 8.2-inch (208.3 mm) pitch are paired with a resin-based carbon-fiber composite structure and PMI sandwich core. A matte finish completes the propeller, which has an average weight of 38 g. The mounting interface uses a flange connection with a Ø6 mm center hole, a Ø12 mm bolt circle and two Ø3 mm mounting holes.

The recommended maximum rotational speed is 7300 RPM, with a recommended maximum thrust of 11.2 kg. Limit values are 8000 RPM and 14 kg of thrust. At an ambient temperature of 22 °C and an altitude of 25 m, performance measurements include 5236 gf of thrust at 5000 RPM, with 1.26 N·m torque and 660.79 W output power. At the same conditions, 7100 RPM produces 10994 gf of thrust at 1982.63 W, with a thrust efficiency of 5.54 gf/W.
