Product overview
HOBBYWING positions the C8020 as an electric propulsion motor for fixed-wing and VTOL aircraft, including installations seeking to replace a 55CC combustion engine. Procurement therefore concerns a motor component rather than a complete flight platform or airframe kit. Those recommendations should guide configuration selection without being treated as a delivery inventory.
The physical design combines a rotor bracket with a rectangular exhaust opening and centrifugal fan arrangement, plus upper and lower steel mesh intended to exclude particles at least 1 mm in diameter. Both variants have published dimensions of 89.1 mm diameter by 59.5 mm height; these are motor dimensions for installation planning. The mounting patterns, shaft diameter and cable lengths further define the integration space. Bracket clearance accommodates folding and non-folding propellers, while an appropriate IPC component and ESC enable selection of the propeller stopping position.
The recommended propellers differ by winding: the 180KV version uses the listed 23×10 through 25×10 options, while the 210KV version uses 22×10 or 23×10. Published maximum thrust is 22.6 kg for 180KV at 48 V with a 25×10 propeller and 22 kg for 210KV at 48 V with a 23×10 propeller. These figures should remain tied to their configurations. The load tables are laboratory reference data at 25°C and sea level, and the maximum-current specification additionally requires a non-hermetic environment at no more than 25°C.
