Product overview
The T-MOTOR AX335-B KV425 is a brushless propulsion component intended for fixed-wing cruising aircraft. The AX-series description presents two mechanical interfaces: a built-in rear shaft and an external propeller adapter. It does not explicitly assign either interface to the supplied AX335-B configuration, so mounting selection requires confirmation. Its physical design includes a hollowed, tilted front cover intended to improve cooling airflow, together with large bearings and military wire. These construction claims provide integration context.
Integration planning should account for the published motor envelope, cable-inclusive weight, lead length, shaft entries, battery range and ESC recommendations. The recommendation panel and detailed table give separate propeller guidance, which should be reconciled for the selected installation. This listing describes a motor component; its packing-list text does not enumerate supplied accessories or establish a complete flight platform or airframe kit. Maximum current and power carry duration qualifications. Published bench results are reference values, with surface temperature measured after one minute at full throttle.
