Arcturus High Torque Neodymium Motor w/ MIM Pinion Gear
(Model: Long / 21 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.
