Systema is is the D-shaped shaft and Classic Army is the round shaft. You can use Prometheus on your CA motor. I've installed them before. You can get a pinion puller at a hobby shop that carries R/C stuff for under $20. Then, hammer the new gear on while putting something sold through the rear bell end and applying counter-pressure to the shaft. Otherwise you'll break the rear bell. Replacement gears cost about $6 each or so, from Asia
