The reason for such concern Owen is that you came to this thread asking about build types, so clearly you don’t know about how to do that, you demonstrated that you didn’t know about ohms law, battery safety, you found wire in your mod (damn!), you thought an autofire was due to a low build, and you called it a mech when it wasn’t. To top it off, when you were given advice to read up on a few bits earlier in the thread you then said that you knew what you were doing. And, in addition to all this, once you identified it to have a mosphet, you continued to try to use it despite it clearly having a lot of safety issues.
Please don’t get a true mech just yet and get that mod checked out properly before any more use.
