Snow wolf SW-020C aug carbine, they good?

What you see there is the x304u mosfet, And a deans connector on the south side of the fet to the motor (fully heatshrunk). That deans connector gives me a QC motor system. I solder the wires directly to the motor with a deans on the end, and can then swap motors at will.
Hi, I’ve just stumbled across this while looking for advice. I have just bought one of these as part of a used bundle and want to fit a mosfet to enable me to use a lipo. This looks to be exactly fitting for me! Am I right in thinking this is wired in without opening the gearbox? If so would you be able to give me pointers on how/ where to fit it on the loom? 

Sorry to open this this old thread but this is just what I am looking for.

 Thanks in advance ?

 
It's pretty easy to do the install of the Mosfet if you are decent with a soldering iron.

You will need a soldering iron, solder, heatshrink, and extra wire.

I have an image somewhere that shows where to cut. Unfortunately it's on one of my redundant old hard drives so I may have to make another one.

Just give me a day or two and I'll have the information you need :D

The red X's are where you cut.

It's then soldered in like this for the XET304u

note your just tagging the mosfet trigger wires into the old trigger circuit, and running a direct connection through the fet to the battery.

You are an absolute star! I presumed it would be that simple but I’m still learning. I haven’t had the need to go inside a gearbox yet as nothing has been wrong. I’m ready to have a go at shimming, but don’t want to open up a gun and make it worse when It’s working fine. 
 

Its shooting hot at about 400 FPS so I need to downgrade the spring as well. As you have knowledge in these areas would you say M100 would drop it to about 350? I don’t know what spring is in there now. I’ve had the gearbox out and worked out the quick change system. 
 

Again, thank you so much for the detail. I’m very grateful. ?

 
I'd probably try get an M100 into it. How hard that is will depend on the gearbox variant. If you have the QC spring system then it'll take a few minutes. If you have a regular V3 gearbox then you will have to disassemble it.

AK2M4 should have springs in stock at a decent price.

It’s quick change so won’t be any bother. Thanks again for all the help ?
