"Trigger response is instant pulling a laylax M120 spring! Paired with the Jefftron Leviathan and SHS 12:1 gears and you’re good to go. The pinion gear on this motor is really well made and meshes perfectly with the SHS gears. Only bad thing is it will generate a lot of heat on semi but that’s normal though.

"Running this Motor in My Krytac MK2 SPR DMR build. It pulls the ASG M135 with ease, and can achieve "Instant" trigger response when paired with SHS 12:1 Gears, a BTC Spectre, and an 11.1 volt battery. (that's with an M135). This is basically a mass produced version of a "FrankenTorque". While its not quite as good as a FrankenTrourque, it is a super easy way to get a super torquey motor that can pull virtually any spring.

"TLDR: if you're looking to extend battery life or pull any spring, this is a GREAT motor. It will require some other upgrades if you want "fast" trigger response. I ran this with a 13:1 gear ratio; I recommend you do the same, unless you're pulling a REALLY stiff spring (_M170 at full stroke). Even there, you *might* be ok.

I got this motor looking for some reliability and trigger response. It's effectively a commercial version of the "frankentorque" motors, except you don't have to roll your own by getting a loose 28-turn armature/rotor assembly and fitting it to a motor can.

Out of the box, this is a REALLY nice unit to hold. Fit and finish is fantastic, and the CNC millwork is top-notch. Even the endbell is CNC'ed.

It's got ball bearings at both ends of the shaft.
The brushes are gigantic, and appear to have a fairly high silver particulate content in them (not just graphite-based).

After putting a few thousand rounds through the rifle with this motor, I'm very happy with it.

On 1000mAh 20C 7.4V LiPo batteries, it's not quick at all, even with the 13:1 gears.
*** If you want trigger response or ROF with this motor, you HAVE to get a battery than can supply a lot of amps.***
The 7.4V above only gives about 40 amps in short bursts, 20A continuous.
I upgraded to an 11.1V, 2200mAh 50C battery (110A continuous, 220A burst), and the difference was staggering.

However, with this motor and good ball bearings, even the wimpy 1000mAh battery lasted me a full day of skirmishing, pulling a brand new Matrix M120 spring.
A faster motor will still draw the spring, but it'll consume a LOT more power doing so. This thing ensures that your ROF and trigger response will be limited by your battery and gear rate, with minimal change across a range of spring rates.
