Product overview
The T-MOTOR P28*8.4 Prop-2PCS/PAIR supplies two UAV propellers with an integrated two-blade architecture. Its physical specification combines a 28*8.4 size, also expressed as 711.2*213.4mm, with carbon fiber and epoxy construction and a polished surface. Weight is specified as 74±3g for a single blade. For propulsion integration, the stated size defines the component’s physical scale, while installation onto motors calls for medium-strength or stronger anaerobic threadlocking adhesive. The supplied configuration is a propeller pair.
Operating selection must account for the 23kg thrust limitation, optimum speed range of 1500~3700 RPM/min and ambient temperature range of -40°C to 65°C. Storage specifications give -10°C to 50°C at less than 85% humidity; separate handling guidance recommends 0–40°C at less than 80% humidity. Inspect the propellers before flight and replace any faulty propeller. Keep use within the stated limits, and do not bend the propellers by hand to assess their strength.
