Allready done:
Prop pitch seems to be two stage in the 3D modell. (on 0 pitch input it turns right to a more featherd position, on anything else than 0 it turns left to its takeoff position. You can observe it when the engines are stoped) However, it have a full effect on rpm in different positions (not just two stages) as I measured:
Throttle 75 %
IAS 200-210 mhp
Height 8000ft
Radiator 100%
Carburetor heat 100%
Pitch % / RPM
100 / 2660
75 / 2520
50 / 2320
25 / 2120
0 / 1760
My findings about the carburetor heat
Carburetor heat seems to work inversely. In 100% you'll get less engine temperature then in 0%
Throttle 50 %
Pitch 75%
IAS: 150-160 mph
Height: 8000 ft
Radiator 100 %
Carburetor heat % / Engine temperature °C / RPM
100 / 201 / 2260
75 / 203 / 2290
50 / 208 / 2340
25 / 221 / 2380
0 / 233 / 2480
Also the carburetor heat controll lever labeld as "AIR INTAKE SHUTTER" (Don't really know how it suppose to work on this airplane)
Also mixture doesen't work at all. Just try a mission with mixture at 0%, then refly the same mission with 100% an you won't notice any difference at all, regardless the altitude.
