A&K STW Motor for STW M4 Series Airsoft AEG

"I have a made a review on this before. After me and my teammates have purchased and ran 5+ of these motors we can definitely agree that when installed correctly, This is an amazing motor. We run them when we are waiting for our blown Systema motors to be rewound. Keep in mind these are still clone motors, so they shouldn't be depended upon, but they are a great temporary motor.
Great purchase, especially for the price that Evike has them. Hopefully they get some more in stock soon.

"This motor is superior to the Systema PTW motor. It pulls the red 150 cylinder better and faster and with the blue 110 cylinder it gives a much higher rate of fire. Comparing the two motors side by side you can tell that the internal windings are better than a systema and wont break.
Bottom line - Celcius=Good. A lower price for a better product.
-Systema=garbage
If you need a replacement motor for your Systema PTW this is the one to get.
One kind of stupid thing though is that it doesn't come with a pinion gear and to get the pinion off the systema one you have to heat up the set screw with a propane torch to loosen up the locking compound that systema put on it.

"Very good motor. Bought this when my Systema 490 motor died. Preformed the same as the 490 in my stock Systema 2011 MAX on Systema 9.6. Good investment. I just wish they were built better, the bottom of my motor cracked- but that was kind of my fault.
Overall, Good motor, Great for the money.
