I've always been fascinated by the late WWII - very early Post WWII Attack a/c prototypes. While most seem to have fairly good info about, the Convair XA-41 being somewhat elusive, I can't find much of anything in print or online about the XBTC-2 (not the XBT2C, sort of a Helldiver II). Heck even a Google on the XBTC-2 comes up empty! Does anyone have any info, other than the very basics, of the XBTC-2? Especially I'd like to find at least a 3 view drawing. I'd also like to know what the XBTC-1 was even! Thanks.
