"For anyone considering this motor as a less expensive AEG upgrade, you will not be disappointed. I use it in conjunction with my G&G V2 gearbox and M120 spring. The bearings are very good. The magnets are exquisite, and the pinion gear is solid. In my four and a half years of playing airsoft, I must say, it has well exceeded my expectations. To my surprise, it has even out lasted my ICS Turbo 3000 motor. It also has a very good balance between torque-which is used to pull tighter springs, and speed-used to spin your gears faster. On a good 9.6v, I can get about
16-20 rps @ 380-400 fps. On my 8.4v, I get round 12-15 rps. If you do consider this motor, a good 9.6v battery will be your best option, for it will not die as fast as an 8.4v."
