I've own 3 of these motors and I have to say this is one of the best on the market. I've pulled Modify M130(25rps) and M140(~18rps) springs with awesome results. They last long and pull fast. Burns out at around 30,000-60,000 rounds depending on battery voltage/amperage and spring rate.
I needed a 9.6v 3600mah batter to power this beast. This was recommended to me buy AirsoftGI to pull an m120 spring in my Systema MP5 expert full tune up kit in my ICS MP5A5. It has a pretty good ROF.
BEST MOTOR!!!!! EVER!!! well value-wise atleast. The only other comparison value-wise would be the guarder infinite torque. It has a tiny bit more torque than the guarder but has a crazy rof. the systema magnum draws a little more current and only has a bit higher rof but for $40 more, isn't worth it. This thing is just awesome. with an standard gb wielding a m100 spring and standard gear ratio I got a peak of 22 rps (right after charge) and constant 19rps with only a 9.6 tenergy battery (yea nothing special)
rof = rape
awesome torque, they don't call this thing m160 for no reason
not the cheapest motor but there is a big difference in rof compared to other torque motors that only deliver torque like the guarder
While this motor produced and incredibly fast rate of fire. (22rps) with my A&K M120 spring and a 10.1V LiPo, the hardened gear set of the A&K chewed the gear right off it after about 3000 rounds. Adjustment was pretty dead on as it stripped the drive gear base to tip without prejudice. Not good, considering the JG motor that came out of the gun did so without showing any wear after 5000+ rounds on the li-po. The JG shoots about 16rps and is going back in the gun. Now I have to tear down the gearbox and clean all the cheap metal out of it from this motor. I'd have to suggest using it only on aluminum gear sets for speed and no higher than a 100 spring.
