Arcturus High Torque Neodymium Motor w/ MIM Pinion Gear (Model: Short / 19 TPA)

"Long - 21 TPA
Placed into a $150 Specna Arms Core M4.
Significant improvement in trigger response compared to stock motor.

"This motor is great! I have it paired with a CYMA Platinum gearbox, GATE Aster mosfet, w/ 11.1v LiPo battery. My full auto absolutely rips! But most important to me is how fast this motor is to respond. The delay between the trigger press and a BB leaving the barrel is nearly non-existent. No matter how much I spam or how hard I run it, this motor constantly stays cool and quiet. I'll continue to use these motors in my other rifles. 5/5 Stars

"Short type. 19 TPA.

Used this to replace my old Gen2 Platinum E&L AIMS. I don't think E&L makes the old M170 motors, or at least has them for aftermarket sale. (I suspect they're saving it for the new E-Platinum line...)

Slightly better trigger response than the old motor! It does whine a little with an ASG M125 (orange) spring. No fitment issues; keep your motor spring and that little steel shim that sits under the motor. Also the blue looks nice.

"Very strong magnets in this motor, I'm guessing N52 magnet rating. Excellent motor quality with even better price!
