Bf109E-3

[Crumpp]

You can not get maximum speed with 100%.

A CSP equipped propeller aircraft will achieve Vmax in level flight ONLY at the highest allowable manifold pressure and maximum propeller rpm.

That is how it works. You can fly with me anytime and I will demonstrate or you can look at your own M20J POH.

Don't confuse a variable pitch propeller operation with a CSP.

Kurfurst would know better but I do not think the variable pitch propellers were very common in the Bf-109E's. IIRC, they were used for a very short time period and were replaced by VDM hydraulic/electric designs.

Most of the propellers VDM produced were hydraulic/electric propellers. In normal operations they were hydraulic CSP's and as a backup for emergency purposes had an electric pitch variance control.
