I've finished practically testing the dedicated racing ships for my atmosphere data project, it seems like some ships such as the M50, P-52, Razor LX, Razor EX etc have rolled back to the state they were in on patch 3.16. The M50 bucks like crazy under speed, the Razor is slow again, the P-52 weighed down by a chaingun is faster than the P-72, a dedicated racing ship. I don't think this is intentional because there was a spectrum apology about the poor state of the M50 and Razors in 3.16 and then the ships were rebalanced to be stable in atmosphere at least until they got more control surface and other work done to them.
