Also, keep in mind that while it IS bigger than the Quadrax/Qx pairing, we're getting the Buchla 281...same sort of idea, but with an additional quadrature function. My applications of the Quadrax/Qx are actually derived from using a 281 YEARS ago, and recognizing that that module was straight-up KILLER. Sure, it takes another 8 hp, but this is one of those times that the extra space is VERY justified.
