Flaming Aces WWII Aircraft Rules

Flaming Aces is a set of free wargames rules for air combat 1939 – 1945. The author writes:

‘Flaming Aces’ is a fast paced and easy to learn tabletop war game that is designed to ‘simulate’ World War 2 air combat with 1/200 scale aircraft (although any size can be used with slight adjustments to the movement and shooting ranges). I say ‘simulate’ because the game’s number one priority is to remain fun, it will roughly replicate the fighting style and tactics of the time but when realism and fun clash, fun will always prevail.
