Product overview
HOBBYWING presents the MSC 21x6.3 as a propeller for multirotor UAV propulsion. Its intended application includes industrial-drone operation in outdoor environments such as farmland, forests, sandy fields and marine settings. Those descriptions establish the manufacturer’s intended use, rather than verified environmental endurance. For procurement, the item should be scoped as a propulsion component.
The model-specific specification table describes a non-folding propeller made from carbon fiber and epoxy resin, with a matte frosted finish and a published weight of 47 g. The weighing configuration is not stated. Mechanical integration is described through direct locking to the motor rotor and removal of the propeller mounting base. HOBBYWING recommends its M5208 and M6215 motors. These recommendations provide a starting point for propulsion selection.
The MSC table recommends 3000–5000 r/min, while the overview gives 3000–5500 r/min; procurement documentation should preserve that discrepancy until the applicable range is confirmed. Recommended thrust is 2.5–4.5 kg, with an ultimate thrust value of 11.0 kg, without supplied measurement conditions. The specification candidates instead reproduce a separately identified folding-propeller block. Its weight, materials, temperatures, humidity, speed and load figures cannot reliably be assigned to the MSC 21x6.3. Accordingly, the facts here retain the specifications explicitly associated with the requested model.
