The Sturmovik Commander website now has a revised force list for the British Royal Air Force for use with their free WWII air combat rules.
From their announcement:
After a long and hard work we have re-done the Royal Air Force for Sturmovik Commander.
This is the hugest and most complicated squadron list update we has done since the release the SturmComm. In fact it is rather completely re-done document. It introduces the Commands system (announced in RNFAA list), which gives the player countless possibilities of composing squadrons. Also it nearly doubles the types of the plane available and allows usage RAF in Pacific/Far East teatre of war.
As always you may get it completly for free from www.sturmovik-commander.com.
