Regarding the Spit 14, that plane was last tested years ago. It's possible that with flight model changes it would be different now. However it's hardly ever flown so i probably won't go back and retest it myself. As I recall the massive engine is a bear to hold in a smooth sustained turn for testing.
However, I will be happy to incorporate anyone's data that is better than my tests in the list and clearly note it was from you!
The only requirements are:
A) You do the calculations to be sure it really is a better number than mine. Badboy's bootstrap calculator is hosted under the same folder as the list.
B) You send me a film of the test so I can verify the speed/time you recorded.
If you need help using Badboy's BootStrap calculator there are threads in here by Badboy himself explaining the whole process.
Since 2006 no one has ever sent me a film. You'd think that folks who are experten in a particular aircraft who feel their favorite plane is being slighted would have sent me a film by now. Or maybe they like being further down the list for sandbagging purposes!
