Well we can start off the cooling from the nightshade is a botched version of the cooling off of the Fi Q. The designs are mostly all old RE designs that Scott Atwell (Fi/AA/Etc) designed when he was still with RE. David previously from RE but now of PSI then sold the designs to Rusty Of DC and that's where they come from. Since the patent laws in china are loose and our laws don't hold any value anyone with a CNC machine and a probe can copy anything without even knowing how it works or why it works.
