The FPS Raijin 25K DCM25KS is the short-shaft variant of the high-performance DC motor designed for AEG tuning and replacement. It delivers a high rotational speed while retaining usable torque for responsive single-shot performance and consistent cyclic fire. The short-shaft format suits replicas and gearboxes where reduced shaft projection or compact motor housings are required.

Performance reference figures were measured with a 13:1 gear ratio and 11.1V battery; real results depend on gearset, electronics and battery used. Confirm mechanical fit (shaft length, mounting interfaces) before installation.

Concrete benefits: improved single-shot responsiveness, stable ROF with appropriate gear ratios, compact form factor for constrained installations.

Warnings & maintenance

Do not tamper: do not open, disassemble or modify the motor; do not alter collectors, terminals or housing. Unauthorized work may void safety and performance.

Installation: requires knowledge of AEG wiring and gearbox mechanics; verify shaft length, mounting and electrical compatibility prior to fitting. Use a qualified technician if unsure.

Testing: perform unloaded and low-load tests after fitting to confirm rotation direction, absence of abnormal vibration and correct gear meshing; wear eye protection during bench tests.

Power & test conditions: reported rpm figures obtained under specific test conditions (13:1 gear ratio, 11.1V). Use batteries and wiring appropriate for your setup.

Storage: keep motor dry and at stable temperatures; avoid corrosive environments and strong magnetic fields.

Safety: discontinue use if motor is damaged or overheats; keep out of reach of children.
