Product overview
The HOBBYWING C8025 is a propulsion motor for fixed-wing and VTOL drones, intended to replace 70CC combustion engines. Its maximum thrust reaches up to 24.7kg when paired with 26-inch propellers at 48V. The rotor bracket combines a rectangular exhaust outlet with a centrifugal fan design to improve heat removal, with a stated 20% increase in dissipation efficiency. Upper and lower steel mesh at the motor bottom provides a barrier against particles ≥1mm in diameter for operation in environments involving dust and rain.
Integration provisions include multiple mounting configurations, clearance around propeller roots for folding or non-folding propellers, and a stator base compatible with a selectable IPC component. Customizing the propeller stopping position requires pairing with an IPC ESC. The motor incorporates a detachable propeller mounting base, an interlocking double-nut adapter, knurled shaft retention and three bearings. Its construction uses 0.2mm silicon steel cores and enameled wires rated for 240°C temperature resistance; that rating applies to the wire material. A custom silicone rubber sleeve insulates the three-phase wire outlet.
