so a few weeks ago, I tried drilling out the holes in my 1.8 ohm i06..wanted to loosen the draw a bit. I used a manual drill like model builders use. Well, the holes got a little bigger and the draw loosened nicely, but now I have a 4.1 ohm i06 running at 6V and working just great...what did I do? I'm guessing I went a little too far with the drill, although I tried to be careful, and messed with the guts somehow...
