I've had these rules a while now and rate them highly.
I've always been unsure about a scale to pick, the system uses hexs to play on and I decided fairly quickly to go for a 6'x4' Hotz mat Hotz Mats . In this size, to get the necessary 45 x 30 hexes to play on, you're looking at a hex size of 1.5 inches, which is what the author suggests. The scales open would be 1/300 or 1/600. I tried both but for me the 1/300 aircraft just looked odd at engagement ranges, way too close so I saved a ton of money and ended up buying some of the dinky Tumbling Dice 1/600 Aircraft .
The rule book covers the 4 periods I'm interested in Falklands, Arab Israeli, Vietnam and Angola and with the Tumbling Dice stuff being so cheap I can do the lot!
Hotz Mat wise I already had a Green European one which will be fine for Vietnam and Angola and do the Falklands at a push but I've ordered a Desert one and Sea one to cover all terrains.
The next quandary involved bases and attaching the planes. The system requires you to record speed and altitude, now you can do this on the paper Maneuver Charts that you game with or incorporate it into the stand. So I'm not sure wether to use the classy plain Litko Stands or the Forge World Flying Bases . Magnets were fine for attaching the aircraft.
