my thoughts on propeller pitch

[louisv]

Watch this video and download the Spit book, also at A2A. In the book you will find the pitch (expressed in RPM...) for each phase of the flight and a lot of other things. Its the Spitfire owner's manual !!! So RTFM and fly away...(I'm sure there is a 109 book too, just not at A2A. Google is your friend).

In the video, there is the constant speed propeller, think of it as an automatic variable propeller as compared to the 109's manual variable. With a CSP (like the Rotol on the Hurricane), the RPM is maintained whatever the throttle setting. Not with a manual variable, like the one on the 109. But the principle of the variable whether it is the DH 2 speed (also on the video) or the Rotol CSP, or simply variable, the principle remains the same.
