I've always admired both the XP-75 & the P-75A, maybe because it's a combo of airplanes & my favorite movie monster being Frankenstein. I had read that the original outer wings were from a P-51 but later changed to the P-40 wing. It used an F4U main gear, which would work well with the P-40 wing. However, if or when the P-51 wing was used or intended, does anyone know if it would have used a standard P-51 main gear or would the wing have been modifed to use the F4U/P-40 gear. I guess too, if they wanted a heavier gear, maybe used a P-47 gear or maybe modified the F4U gear to fold inward without rotating. If they stayed with the inward retracting P-51 gear, the SBD/A-24 wing center section would have had to be modded then. I just got Valom's kits of these a/c & was thinking of getting another & put P-51 wings on it.
