"Swapped my Arcturus stock motor (19,000 RPM) with the 22000. Now I can pull back any spring. I get 500 fps easy. The quality is there; thick wiring. It's the motor I recommend to people.

"Unmatched power. ASG made a small nuclear reactor. I’m using one in a DMR MCX build. Running a heavy duty 125 spring in 18:1 stock VFC gears @ 2.05j. It’ll shoot 3 round burst and a snappy semi all day and it never gets warm, not even warm. It’s the most excellent motor I’ve installed and paired with a gate Titan and 40ms precocking it’s a honor to be behind the trigger. Getchu one.

"Very high performance motor. N52 magnets, .7mm 22tpa helical armature that has been drill balanced. The brushes are much larger and it seems to help the commutator last much longer. This motor is a work of art. The endbell is metal and the plates have insulation under them as well as very hard plastic screws to prevent shorting (double check if you get one for any shorts, if there is any its a quick fix with a hand file, it's tight tolerances)

So with a freshly charged 3 cell lipo this motor stays at that 22k rpm even under load. I have a 12:1 ssg3 setup pulling a sp130 at 31rps, if you do the math that lands at 22k rpm for the motor. 4 cell lands it at 29k rpm which for me was 41rps, the maximum voltage listed for this motor is 12v however it handled the 4 cell without overheating or excessive wear. Other motors with similar specs tend to loose about 4k rpm under load or overheat. I believe its the larger brushes and n52 magnets that help keep the resistance down and the efficiency up for this asg motor.

The motor has side screws that hold the cnced front and back onto the motor, the actual can of the motor is aluminum as well, making it light and not magnetic. The pinion is very nice.

I really was hesitant to spend the money at first but once I used the motor I see why its over 40 bucks. It will outlive 3 shs motors before it wears out.
