Not sure if there is a fix for this issue, but here is the model and then the problem.
Handley Page HP 42 (FSX version) (Original file is HP42vX.zip) . This aircraft was originally fitted with 9 cylinder Bristol Jupiter engines with a low compression ratio and a fixed pitch prop.
I have been reworking some aspects to correct some data via the cfg. file. This has caused no issues and actually improved the general handling to more realistic levels.
The major issue I have is this: The Engine RPM on the gauge over reads by 100%, so instead of idle 500RPM, it shows 1500, 1000 RPM the gauge reads 2000 and maximum RPM which should be 2200 RPM is 3200. I have set the correct HP, cyl displacement in the config file but it changes nothing. I have looked at the gauge xml and can see nothing there that would cause this error. I have played with the scalars for piston engine friction (up and down below 1.0) to no avail and no good change.
I am sure this is not a gauge issue because the gauge merely takes its dynamic data from the main data files. That the aircraft, is as far as raw data, is concerned is developing way too much power, the aircraft take off and flight acceleration is excessive and the speed of the aircraft is also way to high, it accelerates though 80 knots like a fighter and quickly is climbing at 2000 fpm at about 130 knots which of course is completely ridiculous for a low powered heavy biplane like the HP42, which lifted off at 60 climbed at about 70 and cruised at about 90 knots max with a max rate of climb about 500-700 fpm. It was as Anthony Fokker originally described it an aircraft with built in headwinds. I have cross checked all the data in the cfg and can see no significant issues and it all tallies with the original aircraft and engine data I have been able to find.
Are these parameters for power etc actually set via the .air file or via the .mdl file? I am a bit stumped at the moment as to how to fix this. It ruins what is otherwise not a bad sim model.
