Tokyo Marui EG-MAX HYPER 1000 High Torque Long Type Motor For Airsoft AEG Rifles

"If you've bought a Tokyo Marui, there is a decent chance it came with this motor. It is a standard ferrite motor, but is on the speedy side. Believe I got ~20rps on standard gears, tamiya connectors, and a linear m120 spring on 7.4Li. The pinion on this motor is the weakest you'll find on a motor these days since it was designed with soft TM gears in mind. It will pull an m120, but you'll probably need to replace the pinion after a few thousand rounds. If you don't want that hassle, best to keep this at an m110 or lower.
The greatest thing about this motor is that it is really quiet compared to most; with a good shim job, it'll have your replica sounding like a well oiled sewing machine. It isn't going to give you awesome neo motor performance, but it will give you good performance, and let you be a bit snooty about having some legit TM faerie dust parts.
