I do not think that the Aircraft Guide has been updated to keep up with the latest version of BAT, but is still a useful resource, I have been thinking about diving into this subject at least for the info page on the game, the new aircraft have virtually no info as to dimensions, engine operating specs, flight ops...ie..Takeoff RPM, Maximum continuous RPM, Cruise RPM, Manifold Pressures for takeoff, climb out, max continuous and cruise. History of the design, the year it was developed, first flight, when it entered service, first combats and subvariants developed during the aircrafts life time in service, boring to some but interesting to others, I am very HAPPY that the new aircraft are added just kind-a wish the info on the aircraft was added as well, so it will fall to others to fill in the missing data, I am lucky that I have a decent library of older manuals and tech data from the 30's-40's on the various engines used to enable some of that to be uploaded, a good source for aircraft data is the reprint of Jane's Aircraft of World War I and World War II, I have these as well as original copies of Aircraft Design and Engineering Technical Books....Have Fun and enjoy the Game for what it offers, Still going Strong Thanks to all those who contribute and those who appreciate their talents...BAT RULES! SAS RULES!....no I am not biased...heh heh heh!
