Pro Co FATRAT

[GGBB]

Does anyone know what Pro Co has done to the RAT to make it a FATRAT? I'm talking actual circuit and/or component changes not sound. If anyone has any gut shots or an actual verified schematic that would be great. I'd like to update my comparative multi RAT schematic (below) to include this new RAT variation so I'm really curious as to what they've done.

Hey!!! Congratulations on your excellent work.
Not sure about a schematic, maybe somebody chimes in, but in any case, keep us updated
