||I bought this for my CYMA AKM .036. Stock the gun is incredibly accurate; ROF decent and Excellent (360-400+)FPS. After install of this motor, which only took me about 5mins total, while on the "john" LOL! All it took was a four-head screw and wire cutter.
Any-how, after some 1000 tests shots. Currently no crono. But I can say, definitely a increase in ROF, FPS, and trigger response. Bbs fly out in a blink and range is at least 2x farther. Trigger response was instant. Before motor swap, stock I was able to gently pull one bb at a time on Full-Auto mode. The Matrix motor hits fast with about 6 bbs flying out, compared to stock. The Matrix Magnum magnet strength is a bit over rated but it is some what stronger then a CYMA AK .036 motor. Overall test was on a 9.6v 4500mah battery.
Performance on 8v stock battery isn't worth talking about as the differences were not as much noticeable but satisfying too.
Another thing I noticed is heat. This thing heats up quick! After about a mag and a half I notice the handle becoming warm. I'm not sure if this is normal on magnum motors or aftermarket performance motors in general, but heat is a NO-NO...
Faster trigger response
Increased magnet strength
Heats up faster
full stars, I guess not today. If only heat was not so noticeable.
