Not so much an organized report, rather a random sampling of small adventures.
Been trying out Ferram Aerospace provides much more realistic aerodynamics than stock, including stall mechanics and supersonic aerodynamics. I’m still undecided about it though. Makes fairings exciting in rocket design.
I originally uninstalled KW Rocketry due to the unmanageable number of the part set, but lately I’ve reinstalled just the 3m parts. It’s worthwhile for the larger payloads though a bit numerically unstable.
The other mods I’m enjoying in moderation: Kerbal Parts Exchange, Kerbal attachment system, and Kerbal Engineer Redux (though I’m considering going to slide-rule to replace the last one).
