From all accounts I've found, SHS makes some of the most powerful motors available. There is just no comparison to stock ceramic magnet motors. I feel that motors are one of the most important upgrades to make toward improving the performance of an airsoft gun, and because of this and the much higher cost of a motor compared to other upgrades parts I'm going add a writeup about using and modding motors soon.
- Rare earth neodymium magnets
- Ball bearing motor bearings
- No load RPM at 8.4v: 39011.7
- No load RPM at 11.1v: 51282.1
- Long version
Notes on RPMs: These speeds were tested by me so are only as exact as my rather primitive equipment. The 8.4 was taken with a stock Echo 1 gun and battery and the 11.1 was taken with a 1500 mah 20C lipo with a mosfet, super heavy gauge wire and low resistance connections. As with all DC brushed motors, peak power output is at 50% of the above values, this means that if you use the gear ratio (18:1 is what most stock guns are) you can find at what ROF these motors will be pumping out maximum power. For a 8.4 nimh this is not too bad as the current will be quite reasonable due to the lower voltage and higher internal resistance of NIMH. With a 11.1 lipo running at these peak power outputs means you will be drawing maybe something like 40+ amps and would have a serious FPS ROF combo, I do not recommend doing this unless you know what your doing and have the batteries to back it up. Use these values for reference when deciding for high torque vs high speed.
(Max RPM/2)/(gear ratio)/60 = the peak output ROF in RPS
