g&p m4 question

Postby Toonvater » Mon Feb 28, 2011 7:12 pm

so i just got a new g&p sopmod m4 that shoots like a dream. when i got it it had a tag that said 7.2 v only. the only batteries i got with deans are 11.1
would i be putting my gun at risk by shooting with the 11.1
i know i should know the answer to this question but every time i shoot it on full auto the motor gets hot and the bat. gets hot.

Well I can't say for sure what gauge wiring the G&P has but that could be a factor. As for your motor heating up that could be due to misalignment. As for your battery getting hot, a LiPo can safely get as hot as 140 degrees (F) to my understanding and research, but if it exceeds that then you might want to have someone more knowledgeable give input who could help you troubleshoot :)

Anyways, a 7.4 lipo in the deans format from AONW fits and works great with mine. Also, if they are out of the deans format, then you can always convert them or maybe even have the guys there convert them for you.

If you can't get a battery with deans you can change it really easily. I had very little soldering skills and I was able to convert my two batteries and gun to deans and they work perfectly. I would suggest getting a pen soldering iron and I would also suggest putting the solder on the wires then attach them to the deans connector, it makes things a lot easier.

A G&P will be fine with an 11.1v lipo, it'll just have a buku ROF since G&P have stock high speed gears ;)

You will break the piston, and possibly the bearings, if you run an 11.1v in a stock G&P. If you adjust the AOE on the piston, you'll be fine there, but the bearings aren't as strong as some other companies.

I'd run it till it busts, replace the bearings, and call it golden.

i really dont want it to fail on me in a game. so should i take it to aonw to upgrade the piston and bussings before i break it?

No. The size of the battery has nothing to do with forces and stress on the gearbox. It just speeds up the amount of rounds you fire before it breaks. For example if the guns were to break in 50,000 rounds, shooting it at 28rps would get you there twice as fast if you shot it at 14rps. Just run the damn thing till it breaks then fix it. As long as you keep the stock spring in there it should be fine.

Nope, I ran a CA spur gear with a G&P bevel and sector gear a while back. It's the motor that's high speed.

i thought that the lipo could break the gun like if you stick a lipo on a crappy walmart gun. i'm aware about how you have a certain limit before it will break i though he meant it'll break something immediately like after a thousand or two.

FWIW, I have a G&P Sentry that shoots a two shot burst on semi when using an 11.1 lipo. It works normally with a 7.4.

My G&P MK18, SR16, and XM110 have never done that, I guess it's yours in particular.

You'd be surprised at how hard those Walmart guns are to break, actually. ;) See below.
