G&P M249 replacement

[SnowPatrol]

Ok, so I just bought a G&P MKII and my gear just broke, and so I decided to add some more things to my gun too.
My gun is all stock except for the motor which I replaced with a Systema Magnum.

So, I have a couple of questions:
1. Which is stronger, prometheus or systema gears?
2. If I put a 12.8v battery, will it somehow break my gearbox?


Thanks for your answers and for your patience!

EDIT: Removed some questions already answered in the stickies (sry guys for not reading stickies)

Kiddo, did you read the stickies?
if not, please read them first, we are serious when we say read stickies. You're practically asking to get graped in the mouth by a thousand and one angry angry hippos screaming for blood at your noobness.

You'll find out quite a bit of information on AEG barrel length, Gear Type differences, and things like that. I approve of your grammar, but I disapprove of your usage of the "Enter" button, aside from the closing regards. Take a quick second to edit your post and put some paragraph breaks in!

Real quick though: Pinion gear wear sounds like you have the motor adjusted too close to the bevel gear.

Again, make sure you've read the stickies! Other questions will be answered soon.

If you are talking about a 12v NiMH battery, its a bad idea for a support weapon, If you are talking about a 12.8v LiFePo Battery, it is a really bad idea. You will most likely strip the piston instantly (1-2 shots then your piston will turn to liquid plastic) With either of those. THE MOST you should go with a high speed motor is 9.6v. It sounds like all of your Gbox problems come back to your motor spinning too fast.

12.8v battery will likely fire the gearbox faster than the magazine can keep up.

Systema are good gears so are Prometheus. Which gear did you break?

Battery packs are made up of 1.2volt cells, 9 of which make up a 10.8volt battery. Adding a cell to that would give you a 12volt battery. Sorry to nitpick but there are no 12.8volt battery packs.

They have more power delivery than Lipo batteries and are 1.7v more than an 11.1, that means that it will most likely rotate the sector gear faster than the spring slams home, meaning you need to say bye to the teeth on your piston.

Not to mention like Tim said the Box mag is powered by a 3v of AA batteries and will probably not keep up with the load being placed on it

I stand corrected, good show!

G&P recommends a large type 8.4V battery for the stock internals. Mine ran with a decent ROF and stayed up and running for 6 months with an 8.4 3000mah NIMH. I'd try to go for a slower and steady rate of fire with a SAW. You want your gun to stay up for a long time and be able to fire sustained bursts without breaking.

The gears and piston will always be a point of failure. If you get better gears, you'll start stripping pistons.

I used an 11.1v 30c 2800mah lipo with my G&P M249 when I had it. I shoot way too much. That battery fully charged is easily over 12v... And since you're already replacing the gears you should be fine, it's the biggest failure point in G&P guns. I'd recommend Riot SC CNC'd gears and a deepfire piston if budget isn't an option. The box mag I used that kept up great was a MAG nutsack magazine modified to work with the G&P M249. It's not very hard, you just need to cut a hole in the top of it for that brass ring that the bb's go through up into the gun. I'm sure the G&P box mag could keep up as well though, and if not, rewire it to a 9v battery pack. I also used a Systema magnum over the G&P M120 motor. Make sure you insulate the end bell of your magnum motor though. If you want a guide on how to, just ask, or else your motor will probably short out soon.

tl;dr

Prometheus and Likely to OP

I like how this kid has owned every gun ever and has an answer for everything that is better than common sense dictates and his answer for everything is to throw money at it rather than being smart

EDIT: P.S. I like Adam's answer, concise, and to the point

I go through guns pretty damn fast.

[CalvinB]

thats cool, I guess, you should take better care of them then

And if they get destroyed so quick maybe the way you build them up is the reason and people shouldn't do what you say...

Then like Nesta said, your advice is probably moot. Either the fact that you break your guns because you do not know what you are doing, or because your "ideas" haven't been in use long enough for you to know if you are giving good advice or not. Once you have built a gearbox from scratch that works for three years come back and start giving build advice.

OP: I would recommend prometheus gears, and a 12.8 battery is probably going to do some damage in a short amount of time. Like Matt said, a steady, reasonable ROF (not too slow, though) is good for a support weapon.

They don't get destroyed? I trade to use different weapon platforms. I've really only had problems with a few KWA guns and a G&G AK47... The AK47 was my fault though.
