Thanks Maciek, greatly appreciated; this is the info I needed. Talking to Hawke he said similar things and recommended just getting the MOSFET and just gaming the gun with that until something breaks in the gear box that way I can see what was weak and what needs improving. I know that WE takes pride in the fact they shim their gear boxes very well before sending this guns out, and after putting probably about 10,000 rounds through it with 9.6V it's still shooting wonderfully. Appreciate the detail you laid out though.
As far as the motor goes it's definitely a ferrite motor. I am always getting alan kets and other bits stuck to the pistol grips on my CYMA AK and my G&G SCAR, but I don't have the same problem with my WE M4 (just double checked). Any brands/models you would recommend? Just took a look and saw this decently priced Lonex motor:
