The zip file is just both files zipped up and all are provided in case of file corruption of the zip.

While there are minor fluxuations in the RPM of the P51, that's to be expected: Reasoning the engine is producing more power faster than the hydraulic system can adjust for, but it does definitely settle and maintain engine RPM, 2650 I believe: Even down to about 50% power.

On the other hand, the FW setting of 40% pitch (Auto = OFF) is turning about 2600 RPM @ 100% throttle. Reducing throttle in this case reduces engine RPM; @ about 70% throttle ~2300 RPMs. Definitely NOT a Constant Speed Propeller since by definition a CSP maintains a constant engine rpm.

true, there is too much rpm loss while reducing power in the Fw190 on manual mode compared to other CSP planes in game . so we "have" to say the Fw190 in manual mode has a very bad CSP moddeled in game
or however you want call that thing in front of the engine.

anyway, in combat the manual mode is the choice over the auto mode in the BMW driven Fw190s.
