1. What voltage battery are you using? If you are using an 8.4, try a 9.6. 2. Check and see what type of piston is already in your gun (aluminum or polycarbonate). If you want a long gearbox life, stick with polycarbonate. The only way I'd switch pistons is if the stock one was aluminum. 3. If you were to get new gears and you want a crazy ROF, you'd have to downgrade your spring if you are shooting over 350 fps. High speed gears can't handle a lot of torque from the spring. If it were me, I'd stick with the factory gears. 4. The chosen motor is a good bang for the buck, so i've heard.
Remember, these were just my OPINIONS. No need in upgrading things if they don't need the upgrading. I've made the same mistake over and over and over.... if it aint broke, don't fix it.

Sounds like you're starting to become a gearbox wiz there Dom. We'll have to start paying you to fix stuff instead of sending it south, as long as you don't drop anything.

well i use a 7.4 volt lipo which has more power than a 9.6 volt nicad i just heard that the piston break in my gun and the gears are standard ratio and i am pretty sure i have a m120 spring now so maybe i should just go with the motor.

Lol Matt. The only thing that's a pain in the a** is getting the darn gearbox to close all the way. If it were easy to do that, Vito would have his mp5 up and running already.
Viper: Let me know what gun you have so I can do some research on it and let you know what I would personally upgrade. As for now, the 7.2 Volt LiPo battery may have more power, but with 9.6 Nimh's or NiCads, the rof would still be higher. I will look more in depth on this subject, but the higher the voltage, the higher the rof and trigger response.
If you have an M120 spring, you need to stick with standard ratio gears. The only way you'd want to switch to high speed gears is if you were running an insane cqb setup and don't need any more than 350 fps. You can easily hit 20 rpm without high speed gears.
If you were to get a new piston, get a Prometheus or a Guarder. It's the most compatible and even has more life than the Systemas. There was an extensive review proving this a while back.
No need for a new motor until you try a 9.6 first. If you come out to the S.T.A.T. open play the 26th of this month, we can throw one in your gun and go from there.
Just a note: It's always best to stick with stock setups as much as you can when it comes to cylinders, pistons, piston heads, and cylinder heads. The reason being is that they are all tested together to give you the best compression. Who knows if an aftermarket piston will be a smaller diameter than the stock, dropping your compression, resulting in a major fps drop.
Any way, bring it out to an open play and try out a 9.6 volt Nimh or Nicad and we'll go from there. As of right now, in my opinion, that's the main reason your rof is hurting. I may be wrong, so let me know what gun you have and I'll do some research.

I believe he has a G&G SCAR light.

Just a side note on lithium batteries of any type, be it airsoft, AA's, or a Dewalt 18v battery pack. Lithium does NOT give more power in any way shape or form. It lasts for more cycle times(the number of times you put it on and take it off a charger), and has a slower deterioration, meaning if a nicad deteriorates at 5% per week, lithium deteriorates at 1% per weeks, meaning if you fully charge it, then leave it off the charger for a month on a nicad you loose 20% of the charge from the battery on a lithium you only loose 4%. those are the only 2 differences between nimh or nicad and lithium.

K. Thanks a lot for clearing that up. Makes a lot of sense. I couldn't find anything on rate of fire or anything between them, but with that, the 7.2 lipo is no quicker than a 7.2 nicad or nimh.

i have 2 9.6 volt batteries and they perform worse than the 7.2 volt lipo i heard that the 7.2 volt lipo puts out 32 joules and 9.6 volt puts out 30 so the lipo has more power

Force is measured in joules. I think you mean amps. And a 7.2 Volt lipo should actually give a similar rof of a 9.6 Nimh battery. However, lipo's don't suffer from the dreaded voltage drop that Nimh batteries do. If the Nimh battery is of a large size and Mah (2600 or greater), they don't suffer anywhere near as bad as the smaller Mah Nimh batteries do.
I stand corrected about the rate of fire problem. However, I still don't understand why your rof is suffering. My guess is the motor. If you know how, take the motor out, get a screwdriver (medium size) and attempt to hold it up with the motor's magnet. If the magnet seems pretty strong, it shouldn't be the motor. I'm kind of stumped on this issue.
What's the mah on your lipo? And what is the mah ratings on your 9.6's? Are they mini tamiyas or large type?
And about the 7.4 volt lipo. The output of over 30 amps can occur with both types of batteries, lipo's and Nimh batteries. My 9.6 Volt 4200 mah battery puts out up to a 40 amp discharge rate. The discharge rating on batteries means nothing if you have a weak motor. The motor draws what energy it needs to operate (usually around 20 amps). That's why most guns come with 20-25 amp fuses. Your motor is not even using your 32 amp output from your lipo because it doesn't need it to operate.
What I would do.... Get either a G&P Motor or a Systema Magnum. However, you should expect a lot of wear and tear with the Systema motor.
Sorry that I couldn't help any more. That's all I can think of.

I use a 10.8 in my CA with a magnum motor and only problem I've had is with the wiring. Next time you come out Isaac we can try yours with the 10.8 and see if it helps your ROF.

Is the battery a Ni Cad or a Nimh? I have trouble with Nimhs sometimes, if you don't charge it just right they won't even turn over a stock gun. That's why I need to stock up on Ni cads before they become outlawed...

1. I use Nimh's (Powerizer 4200 mah - 9.6 volt) with a trickle peak charger that stops charging when the battery is full and haven't had a problem. The problem with Nimh's is that you don't get a desirable charge with quick/speed chargers (personal experience/so i've heard).
2. Where did you hear that NiCads were being outlawed?
I now know how to make batteries, so if anyone needs to custom fit a battery into a stock or cramped space, just front me the money for the parts and I'll be happy to do it for free. It's rather fun assembling them.

well i fixed my problem with a G&P M120 Ultra High Speed Motor (Long Type) it works great, doubled my ROF with 7.2 volt lipo still lol
