As a good rule of thumb, it is recommended that a gear box be properly reshimmed, and the aoe be corrected previous to running an 11.1v LiPO. That being said, I've thrown caution to the wind and haven't performed either of these (ducking from the rath of Ike), and have been successfully running 11.1v for the last 2 years on my KWA.

No problem. Looking at the link you posted it says the MOSFET is protected from voltage spikes, not the gun.

First thing I want to say is I am really liking this Forum allot!!! You guys have been so cool taking the time to talk to me and help me fill in the blanks as I come across questions as I am learning!!! Yeah that's what I was saying is I didn't really go over the info very good. To me it looked like the MOSFET was something to control the voltage to the motor. That's what makes this Learning and not knowing...I have nothing else to say tank I don't know if I want to push the Lipo's just yet on my guns. I think I am going to do some more research on that first. Plus I am going to try out one of my voltage regulators for my RC Cars and see how that goes. Heck maybe I might be able to share some new info to you guys soon. Thanks again for all your Help. I appreciate it. P.S. You guys were killing me on all these abbreviations but luckily I found a helpful tool...I have nothing else to say forum.filforce.org/default.aspx?g=posts&t=1254But what does "AOE" mean? Only thing I found was Area Of Engagement. And i don't think that is what Tank ment. |

That's correct. Specifically he's referring to shimming. When shimming the goal is to have the gears mesh with as much surface area as possible to reduce wear.

In Rc's we pretty much do the same thing. The gear on the motors we have to take a piece of paper and stick it between the motor gear and drive gear and that basically give us the tighest application without putting too much strain on the gears.
I think I have to tear my sons G36 apart. We hooked a battery up last nite and it seems like the gears are locked up. I can hear the motor want to Cycle but it dosn't go anywhere. No BB's are jammed up so I am thinking it's internal. Any advice before I tear into it? Thanks!!!

Discharge and recharge the battery, I'm assuming you have a smart charger since you were into RC. Make sure you are able to put a decent amount of energy into the battery. Second thing to check is the motor height adjustment. If it's a new gun this is unlikely to be the problem, but there should be a small allen or flat head adjustment screw on the bottom of the pistol grip. Slowly unscrew this while occasionally pulling the trigger. If it gets to a point that you can tell the motor is spinning and the gearbox is not, then yes there is likely something binding up the gearbox. At which point in time try to screw it back into the original position. This will require some tinkering later to get it into the perfect position, but basically what you will have to do is get it to a position that results in the least amount of noise. That's generally a good sign that you have it in the right spot.

I'd double check the battery is still strong first, the box will lock up with a dead battery once it doesn't have enough power to cycle the spring. This will seem like the box is locked up or somethings wrong internally because you can still hear the motor trying to turn, which would mean "okay i've got juice" but it might just be the battery has enough power to engage the motor (you hear that) but not enough to cycle the spring. It also could be the motor itself is out of alignment far enough that it isn't turning the gearbox over. This is adjustable Double check it with a full battery just to make sure before you break it down. It's been yearrrs since I've opened up a gearbox but they aren't bad. just watch the spring tension when opening it, you should see how everything goes together, they're relatively simple but someone who tears into mechboxes daily or weekly can give you better insight to specifics on that I bet. EDIT: ^^^ Like I said someone else will get back to you with specifics. Damnit X!  |

No this gun isn't new. I bought it off a friend of ours and I am sure it has been used pretty good. I have had problems with this gun since we got it. Before it just wire issues with the wires pulled out from connectors. I will try discharging and recharging the battery now. It's a brand new battery but that don't mean anything. So I will start out simple and go from there. This will work out good for me, if I have to open it up because And I mess this up I won't be out any major money...I have nothing else to say I will keep you guys updated!!!
Should I put this on a different Thread or is it ok to just keep all this going on the same Thread?

The easiest reference for mosfet explanation is imagine a relay setup for car's headlight. The electrical signal from the switch stalk on the steering column(or dashboard area) send the signal to the relay and the relay pull the main power load from the battery to light up the headlight bulb instead the headlight bulb direct connection that run thru the switch stalk. the relay(mosfet setup in airsoft gun) will redirect the amperage load from battery thru relay instead of the heavy amperage flow thru the tiny contact from the switch stalk.
