Here are a bunch of pics
Here is how my first attempt at the Chimera trigger board install went....

I knew I was going to want a switch in line between the battery and the mosfet so that I wouldn't have to disassemble the stock to take the battery off (since its an computer mosfet, it will slowly drain the battery as long as its plugged in). This is how the switch looks in location, with some random wires soldered on for testing. This is in the neck of the sock btw.

The next 3 are a few shots of how the battery lives in the stock. Its only a 7.4, but thanks to the pre-cocking option of the Chimera, the trigger response is instant.

^Its pretty easy to reach under the cheek rest to get to the balance wire of the battery, so I can charge it without taking apart the stock.


Unfortunately, it would not be very easy to shorten the data wires that connect the Chimera trigger board and brick assembly. Luckily, there is a lot of space here behind the GB in the lower receiver for me to coil them up.

Here is more of that neck of the stock, with the battery coming in from the right, and the switch mounted underneath. ... As well as the brick of the Chimera. I'm very glad I added the switch, because otherwise I'd have to get back in here to disconnect the battery every time.


Here is that section all closed up. This switch on the externals of the gun is AWESOME, makes programming and adjusting super easy.... Clearly, I will be hitting those screws that mount the stock to the body with some black paint.

A few full shots, before the switch was installed.
