Product overview
The HOBBYWING C7225 serves as the cruise propulsion motor for an electric fixed-wing UAV. Procurement therefore centers on selecting the 160KV or 190KV variant and integrating the associated propulsion components. The manufacturer presents it as an electric alternative to a 40CC combustion engine. Its recommended configurations pair the 160KV motor with a 24x12 propeller and the 190KV motor with a 22x12 propeller, using a 12S LiPo battery. These combinations are recommendations.
Physical integration depends on the published motor envelope, mounting patterns and propeller interface. Both variants measure 80.9 mm in diameter by 62 mm high and weigh 755 g including wire; these are values to confirm for the selected configuration. The rotor bracket combines a rectangular exhaust outlet with a boss arrangement accommodating folding and non-folding propellers. A detachable adapter incorporates interlocking features, while standard titanium alloy nuts secure the propeller mount. The shaft retention arrangement and triple-bearing construction further define the motor's mechanical architecture.
Electrical propeller locking components are optional, and customizable propeller positioning depends on a HOBBYWING IPC ESC. The recommended ESC choices and mounting dimensions provide specific integration references rather than a universal compatibility assurance. The published maximum continuous output differs between variants: 850 W for 160KV and 770 W for 190KV. Maximum-current ratings require non-hermetic conditions at ambient temperature no higher than 25°C. Thrust and load-performance figures require their stated voltage and propeller configurations; the laboratory data are reference values measured at 25°C and sea level, rather than promises of aircraft performance.
