so i just charged my lipo completely, and plugged it in to fire for the first time after taking the hopup apart with van guiding me. I put the hop back together,then plugged in the newly charged battery, which I had not charged prior to taking the hop apart, but used the small amount of charge in it. On semi, it fired full auto, but not consistently, like 2 or 5 rounds then stop, and the bbs dropped fast sooner than usual. I'm using a 1200 mah 15c lipo. It read 12v fresh out of the charger. Thanks

Ok.

Electrical:
- Did you do any work to the gearbox or has anyone else worked on your gearbox?
- Did you ever remove or replace the motor with an after market motor?
- Do you have a fuse installed?
- Make sure to fully charge the battery.
- Try a different battery and see what happens.
- Check the wires as you close the upper receiver to make sure they are not getting pinched somewhere.
- Typically, if it is firing Full-Auto on Semi-Auto setting, you have metal touching metal somewhere
   in  your electrical wiring. This could also be from arching in the Trigger Contacts.
- Make sure your Selector switch is locked into the Semi and Full-Auto positions before pulling the trigger.
- Make sure to fully compress the trigger. No half pulls

Hop-up:
- Make sure that the barrel window is centered with the Hop-up window.
- Make sure the Nub is seated correcrly.
- Test the function of the Hop-up unit by pressing on the Hop-up Arm to raise and lower the Nub.
   Make sure you see the Nub raise and lower the bucking mound as you press and release the
   Hop- up  Arm.
- Make Sure the inner barrel is fully inserted into the Hop-up unit all the way.

on the hop up bucking seems to protrude VERY slightly when turned off completely, and i have a fuse, its a completely stock kwa- deans connectors, which worked prior to taking apart the hop up, and the barrels all the way in, and the hop up works. Some little wire came out of a rubber tube on the black connector on the gun, and i put it back, could that cause a problem?

Then check back.

Ok me and Van ran through the list, other than using a different battery, because so far the lipo's the only one I've switched to dean's. I have a feeling it may be the lipo causing the problem, but does anyone have any other suggestions?

You should pick up one of these parts and a new battery.
Yes is will be a few bucks out of your pocket, but that is just the way it goes sometimes.
This will give you a back-up plan so that your gun always works when you need it and an extra supply wire for future use. The Parts I list will cost you $35.00 plus shipping.
Not bad, if you ask me.

So I know this forum is old, but I'll admit I gave up since the supply wire was out of stock. I decided to plug it in today, a year later, and it works great! My conclusion was that the battery was overcharged. The only question I have is that it will make a lounder noise, then a quieter noise, then a louder noise, and so on. Both shoot the same, has anyone else experienced this with a gen.1 cqb and a 11.1 lipo, or any gun?
