Longest Life - Tokyo Marui
Most Power - SystemA Magnum
Fastest ROF - SystemA Turbo
Best Value for your Money (in my opinion) - G&P (they make high speed and high torque versions)

Thanks for the reply guys. The reason I need a new motor is because after 2 hours of trying to get it out i decided to hammer the grip...I quickly realized that the grip's plastic is alot tougher than the motor :/

Most likely not the best solution, but I reached my limit with it lol. I read up on the G&P m120 and it seems like a safe bet. The only thing that worries me is getting the shimmings right.

You don't shim a motor; only the gears inside the mechbox.

The motor is height adjusted through the screw on the bottom of the grip. The most common method is to screw the motor height as far up as it will go then back it out 1/2 turn. Keep backing it out by 1/4 turns pulling the trigger in between with the gun on auto and you will notice the rate of fire increases. This is because when too high the motor binds and wont spin as fast. Once the rate of fire stops increasing (remains constant) as you back it out you need to find the point where it makes the least noise. If you back it out too far the gears wont line up properly and can either slap each other instead of meshing properly or grind and strip. The point where you have maximum rate of fire and least motor/gear noise is the proper motor height.

Oh that explains alot lol, thank you! I guess I'll have to wait until I get the new motor to try things out. Thanks alot for the replies, really appreciated and helped a bunch

edit: I've read somewhere that you need to adjust the gear height to match the height of the motor, is this true?

The gears can't be adjusted for height. They can be shimmed side to side to keep them from moving and to keep them with the most tooth engagement without binding against each other. There may be some weird mechbox design that allows for adjustable gear positions but normal mechboxes don't.

Do note that some grips place the motor at different heights. The Magpul MIAD and MOE grips are bad for placing the motor really low so you need to max the height adjustment to get proper engagement. Sometimes even at max adjustment its not high enough and you get grinding. Also since they use brass for the screw and opposite threaded insert its self lubricating to a degree so is also known to wind itself out after a while (a few thousand rounds normally.) You don't know its happened until in the middle of a firefight your gun stops firing and just makes a grinding sound. It can be fixed with some blue loctite (red is permanent, blue is not) but since most grip screws don't need it many people don't put it on and have the motor drop during games.

Hmm sounds like some grips I'd want to stay away from haha. Thanks for the heads up. The shimming cleared a lot up as well. Thought shimming was height adjustment :/ Apparently the G&P m120 is mass produced due to the fact that they are stock motors for G&P guns, I guess that would mean that they are bad quality? Also what does the "eg" stand for in the tokyo marui motors? In ever other motor it has "m" followed by a number which I assume describes the power of the spring.

g&p motors are mass produced, but they are of a great quality. out of about 15 i have bought none have arived DOA. (ive only bought 15 becasue i kept stripping pinion gears.)

i run M140 short types in my M249 and G36, M120 in my AK47. amazing rate of fire, especially when paired with a highspeed gear set.

EG10000, EG1000 and EG700, they are TM stock motors. I cant tell you what it means, it may be the cyclic rate. just that the 10,000, is a highspeed motor, the 1000 is slightly less fast, and the 700 is a torque motor. the QC on them is amazing, and they last forever, i have a 10,000 in my M16, and a 1000 in my 416, and had a 700 untill it stripped its pinion, due to aforementioned magpul grip.

The EG simply stands for Electric Gun. Tokyo Marui actually started as a hobby model company, specifically with electric trains, and started using the EG designation for their airsoft motors. It has no specific meaning past that.

15?! haha wow. Hmm so I guess it won't really matter whether I pick TM or G&P since they're both good companies. Worst comes to worst I can just order an extra pinion gear ( http://www.airsoftparts.ca/store2/index....cts_id=673 ) in case the one on the motor strips. Also does QC stand for quality control? That's the assumption I always make when I've been seeing it lol.

Hmm I expected "eg" to hold more significance then just that. Thanks for clearing that up. I guess when it comes to TM, the higher the number the better? Except for the 700 since it's a torque.

They're just model numbers, not in terms of "better". Is an F-150 better than a Mustang? Depends entirely on what you're trying to accomplish.

As are all airsoft motors.

SystemA claims "hand made" but all they really mean is a person wound the wire in the coil but it was still an electric motor driving the winding process instead of an automatic spooling machine. Most airsoft parts are actually too low of a production number to qualify as truly automated and all airsoft components are "hand made" to an extent. I can almost guarantee you that all airsoft motors are hand assembled from the finished components since even in Canada things like that are done by hand. All finished airsoft guns would also be hand assembled and even mechboxes would have to be put together by hand (automated screw drivers and the like but parts still placed by hand.)

I guess what I meant by mass produced was that they have less quality due to the fact that they are used as stock. Upgraded motors would have more "specialty" than the stock motors. I read that the quality of pinion gears are also not that good on these stock motors, which would make sense. In the long run I would assume getting G&P m140 would be better than the m120.

All motors are mass produced one way or another. They all fail in their own way and no one motor is 100% the best. They all work as intended and fail when they feel like it.

In my experience TM have the most durable pinion gears and G&P are pretty damn good too. The problem with the SystemA motors is they used a metal so hard for the pinion gears its brittle so it can crack and the pinion gear can split and fall off the motor.

So the most expensive motors have the worst pinion gears

I like the ICS Turbo 3000 motors. They run damn well and have been really reliable. But my opinion on TM is the same as lutnit.
