Vector not firing and other issues

Greetings to all! Recently my KVV2 stopped firing and I first supposed the mosfet was fried. Ordering another mosfet online, I realised it happened to be the 2 pin, 3 pin , 2 pin , 4 pin version which LG showed in his mosfet change video.

Changing the mosfet, i rewired according to LG’s method, as shown below:


After plugging in the 11.1V however, it still doesnt fire! At this point, i have no idea what is the problem. I tried fiddling with the fire select but there is no difference. Any idea what should i do next?

On another note, I disassembled the gearbox in the KVV2 hoping to change the O ring, cylinder and barrel. While the O ring change is straightforward, however the stock cylinder’s nozzle was attached to the cylinder itself. How can I remove it to change the cylinder? This also happened for the barrel itself, where the T piece is stuck to the barrel. How do I remove it? Do i heat it up?

Appreciate your advice please, thank you!

Update: Ok apparently the cylinder head can be yanked straight out.

i’ll look over this again in the next day or two for you but if you followed LG’s method it would be hard to go wrong
