Larry Ernewein has made numerous updates to the Tigre document he and Karl Pfister wrote and kindly shared via this website.
You will find the new document in the Downloads section of this website. Navigate to "Engines" then "The Tigre" or just click here. This is the best way to get a copy that you can print and take to the hangar.
You can also view it in your browser by clicking here. Once again, thank you very, very much Larry and Karl.
