Just realized that I forgot to post the link to the forum's beta testing thread - you may find it at Memes.no
While the beta is indeed a beta, I'd highly recommend playing whatever's listed there over previous versions of Flak. Betas are also updated almost daily, so if you find a bug or have a suggestion please post it in that topic! This way, it can be seen and worked into the next beta.
As of now the beta is at RC42, or Release Canidate 42. I know, that seems oddly high, however it is in fact the 42nd beta deemed ready for release on Lancers Reactor. Betas will not be posted in the downloads page for Flak's ModDB profile due to how often they are updated.
So long and until next time.
