"I ordered 3 of them and installed them in combat machine bodies. All chronod 350ish. Only issue was the positive motor wire was short. 99% of the time both wires are supposed to come up the backside of the grip for proper motor alignment. So with the wire being short, the only way we to run the positive up the front side of the grip but then the motor wouldn't fit because of the wire. Once I extended it 1.5 inches everything was good.

So far so good. No issues.

"So I ordered this gearbox to replace the gearbox is on my JG M4 s system. When I got it instead of having flat connectors it had banana connectors which was a total pain, because I can't find the flat connectors to replace them anywhere. Note the picture has flat connectors. So I had to cut off the banana connectors ( which means now I won't be able to return it ) and replace them with flat connectors. Once I got the gearbox put in the gun and everything connected. I started to test fire it, only to find out the cylinder head was too small for the cylinder and got sucked back with the spring and jam the spring back. Bottom line is I got a faulty gearbox and since it didn't come with the right connectors I got stuck with it. I ended up taking apart my old gearbox and replacing the cylinder head with one of my old ones and it fit perfectly go figure. I'm not having any luck with JG products and will not be buying them anymore. It seems their specs don't match their products and it's hard to find replacement parts that work.
