G&G CM16 Raider motor generating a magnetic field?!

Ok, so after attempting to game this gun with an upgraded madbull ultimate hop-up unit, i found out quickly that it wasn't firing. The bbs were unable to load correctly into the barrel sleeve, so i sanded it a little bit to the point where it would drop into the barrel and sit a bit behind the hop up nub. Still wouldn't fire. checked the nozzle, and it seemed like it wasn't cycling back all the way to allow the next shot to load. Took the whole thing apart. Did what I could, realigned the gears, greased the gearbox, etc. Now, the nozzle operates but locks back, which seems ok... but now the motor that sits in the pistol grip is generating a magnetic field. I have no clue what I did to cause this, but I'm pretty sure it wasn't like that before. I don't usually have problems teching my own guns either so i have no clue what the hell i did now.

Anyone have any ideas?

Not sure what you mean?

Magnets are what make motors work.....

That strong? Ive got an allen key 3/4 inch away and i can feel the pull. So it's supposed to be doing this? I guess since it's the first time i've dealt with an AEG motor i didn't know. I didn't think it was magnetic before, i never noticed anything.

There are magnets inside the motor.

It's likely you just didn't notice before that stuff made of metal would stick to the grip.

Unless of course we're talking about pulling the trigger and you get some sort of effect like this, Compressed Hare - Road Runner & Wile E. Coyote - YouTube

Nothing THAT bad lol. No, just the motor is inside the grip and the allen keys are sticking to the plastic. trigger pull or gearbox operation has no effect (that i see). i hope its alright then. thanks.

alright and the nozzle staying back is ok? doesn't that put pressure on the spring?

I can pick up multiple full size screwdrivers or vice grips with some of the motors I have.

I lol'd
k so first, there's no such thing as gear alignment, everything is "timed" off of one gear, so it doesn't matter what rotation the other two are at.
Second, the air nozzle moves back and forth during normal operation. Sometimes it will stay in the back position because that's where the sector gear stopped.
However, if the nozzle is in the FORWARD position, and it requires quite a bit of force to move it back with your finger, and it doesn't snap back to the forward position freely, then you have a problem. Most likely the sector gear was shimmed too close to it, and it's being pinched between that gear and the mechbox shell.

Don't worry about springs, they only wear when they are in use. You can leave them compressed or stretched for 7 months and they won't lose more than 3% of their strength

I'd say more like 3.27% but that's close enough TC.

Maybe you didn't replug the nozzle with the tappet plate correctly, and it doesn't move as it should too. Nozzle should travel back and forth while operating.

4 fps from 412 after 7 months of it being fully compressed

... I'm used to paintball markers which are a lot more simplistic. This is the second gearbox I've opened. I don't know that much about airsoft guns yet, that's why I asked.

Before I opened the gearbox, I think the nozzle was able to be pushed in before springing out. If being retracted is fine, then I won't be screwing around with it anymore.

Yeah but you guys forgot to factor in coil pitch and number of turns... *facepalm*

That would equate to the 3.27% (a well known constant of course) times coil number divides by the square root of coil number over pitch

Damn these guys that call themselves gundocs! Can't believe this!
