Question about motor.
« on: September 04, 2012, 06:19:20 PM »
I have a G&G combat machine, and once in a while the motor does that screeching sound (obviously its not good.) But i take out the motor and the gear looks fine, i put it back in and it takes a bunch of turns to get it to shoot properly. Some of my air soft buddies said it should not be in that far, So do i have the wrong length motor, maybe i need to get a long type? Please help.

P.S. i have been having a problem with my hop up, I recently got a new barrel, and when i installed it, it seemed fine, but when i shot it.... its range was about 30 feet, the hop up thing you turn to adjust it, doesnt work, i put it all the way up and it still shoots like crap. Some people are saying maybe im missing a nub, but i got that, im pretty sure im not missing any pieces.

Thanks in advance

There actually is a really small piece that is in there that is really easy to lose, and happens usually when you're replacing a barrel. It happens more often when you don't turn your hop up all the way off.

for the barrel, remove it from the gun (with the hopup unit still attatched, making sure that you have the hop turned all the way off.) and look down the inside of the barrel from the front.  next, rotate your hopup knob to give it more hop. as you do this gradually, still looking down the barrel, you should see a little nub start to progressively protrude from where the bucking is. that little nub (when your hopup is turned up) of what puts the spin on your bb, making it fly straighter when fired from your gun.
if you look into this, idk maybe you could better help diagnose whats wrong with your gun.
Also, make sure the bucking isn't all bunched up. remove the barrel from the hopup unit and maybe lube it up with some silicon oil, and reinstall. shud go into your hopup unit smoother.

As for the motor, ALL M4's use a LONG-type motor.
I realize that while most people suck, there are still some genuine characters that exist out here. I'll show my appreciation by being genuine in return.
Love the sport.

could the pinion gear be lose? as in not griping the motor shaft 100% some pinons are press fit and others have a grub screw to secure it to the motor shaft i think

How long have you had the gun? One of my M4's had a loose adjustment screw so when I fire for long periods I time or am out in the field for a while it loosens from the vibration and gives me that grinding noise you are hearing.
