Drakker,
I switched connector to Dean. I had 3 batteries 11.1 1100mah. Worked well at home, but I decided to reduce the FPS to increase the durability of the gun. The MP7 has a quick spring change (Thank God), I cut a linear spring that I machined (no conventional format) for the size of the gearbox. I reinforced the extremes and I now arrive at 336/340 fps. It's perfect, I need nothing more.
