Product overview
The HOBBYWING RTF 5315 is a propulsion component for FPV drone integration, offered in 220KV and 360KV versions. Procurement should therefore focus on the motor variant and its associated electrical and mechanical interfaces. A motor product rather than a complete flight platform or an airframe kit. Its application guidance pairs each variant with specific propellers, an ESC and a LiPo battery. Buyers should confirm the actual delivery configuration.
The physical design combines a laminated stator, multi-strand enameled-wire windings and arc-shaped magnets. HOBBYWING describes a self-cooling propeller mount, a toothed interface intended to resist propeller slip, and rotor retention using copper washers, circlips and screws. Integration planning can use the published axle, propeller-mount and motor-mount specifications, together with wire length and weight including wire. The displayed motor and stator size entries omit units, so those dimensions need confirmation before allocating installation space. Cooling and winding benefits remain manufacturer claims.
Electrical selection follows the variant: the published combinations associate 220KV with 12S LiPo and 360KV with 8S LiPo, each using its named RTF 100A four-in-one ESC. Both recommendations list the same four HQ propeller options within the stated 15–17 inch, three-blade application range. Maximum current is qualified by non-hermetic conditions, ambient temperature at or below 25°C, and a variant-specific duration; maximum power also carries a duration. Published maximum thrust lacks a complete measurement setup and should be assessed for the selected configuration.
