Check the Spitfire Mk IX again as well.
I can never remember which is the better turn direction for each aircraft, but there are a few that turn better the other way. La-5FN, Spitfire Mk XIV and Yak-9s as I recall.
Good Spot on the Spit 9, it was not right. Corrected in Rev 2. I also checked the 5, 8, and 16, they all had minor changes but were very close to the old data, probably within experimental error. They are also changed in Rev2.
As far as Left vs Right turns, there's no way I'm going to test all the planes in both directions! I did some testing in 2006 on a couple of planes that folks said turned better one way but I could never get them to have a significant difference. They may be easier to turn Left vs Right because of Torque control issues, but that doesn't mean that actually turn faster, just easier to hold at the stall limit in one direction.
I may be wrong, and I invite anyone to film tests of planes that you think turn better, send me the film, and I will be glad to change the data and note what direction it was turning. And you'll get credit for doing the tests in the notes section.
