Corsair with Variable Pitch Prop, some refinements ...
Whomever submitted the original, did a great job ... love the features and look. Great model to modify.

Variable pitch prop will keep prop speed somewhat constant with airspeed. Some variation allowed so that the engine sound seems more natural with throttle settings.

What you may notice:
* Good pulling power - loops and vertical
* Higher engine speed on landing due to lower pitch of prop with low power settings.
* seems to have better speed control during landing, but requires a higher throttle.

Refinements:

What you may notice:
* Cowl Flaps change positions with engine RPM. Even at same throttle setting, the flaps change position.
* cowl flaps will close with engine shutdown.
* Some smoke adjustments.
* Simulated "Corsair Whistle" sound with airspeed.
* Flaps automatically retract when wings are folded ... return to selected position when lowered.
* Knob for flaps only requires ~ 1/4 turn for full down.
* prop doesn't look correct because variable pitch props are limited to what I have found on these swap pages.

Flip the switches and turn the knob ... see if you like this variant.
