Matrix Performance Airsoft AEG Motor (Type: Magnum - High Torque / Medium)

"Slapped one of these high torques in a m4 lmg and it rips. With standard 18:1 gears I got 28rps with a 11.1v 5200mah LiPo. Trigger response is terrific especially when paired with a micro switch trigger. Latter placed it in a featherweight m249 and does about the same. Runs cool all day. Pinion gear has zero wear after thousands upon thousands of rounds with it. I believe they fixed the pinion heat treating issue after many people had problems with it in the past.

I plan to buy more. Overall 10/10.

"So this is a review that I think a lot of people could use as guide, but it's up to you. As a person who works on guns and builds every last part to specs that I want, these Matrix motors are awesome for changing performance to your liking. I recently bought two of the Turbo 3000 medium motors on sale to turn into 28 TPA and 32 TPA frankentorque motors. Even at $40-45 dollars, they're worth the money. I've used them many times before and they are reliable motors. This applies to the Matrix 5000 motors as well. I don't know the exact OEM, but I'd wager AIMTop on that. There's a lot to like about these if you want to build your own motor.

*Pros:

- Ridiculously strong neodymium magnets. There aren't a lot of brands that have as strong of magnets as 'Matrix.'
- The endbell and can use a lock ring, making disassembly and swapping armatures a breeze.
- I think the pinions changed a bit over time, but they seem to be a bit harder. It is a D-type.
- Magnets are well shimmed to the *stock* armature. They fit Chaoli armatures well though.
- If you want to use the motor as is, the armature is well shimmed to the can and endbell.
- Brushes are fine. They are horizontal, but they're bigger than others and they don't spew carbon everywhere.

*Cons:

- Sometimes the pinion gears are really stuck on the shaft of the armature. Swapping it can be tough at times.
- I wish the armatures were balanced via drilled pits as opposed to epoxy.

In conclusion, Matrix motors are an awesome buy at a reasonable price point. From a tech's point-of-view, there's a lot to like with these out of the box. Aside from swapping armatures to change performances, everything on them is nice and it comes with a great neodymium can. With a 32 TPA armature, your AEG will be slow but will be able to pull anything, never get hot, have excellent battery efficiency, and yield nearly instant trigger response.

"Purchased the short type turbo 3000. Wow, with a 9.6 it spits bbs out very very fast. On an 11.1 its insane. Very strong magnets. I had to add a mosfet with active braking because I was getting overspin on a 9.6 sometimes with an m110 spring. Definitely recommend!
