Convair Pitch

[jwh]

Is there an adjustment that can be done in the aircraft .cfg file for the nose-up and nose-down trim of the various FS9 Convair 240, 340 and 440 models? I'd like to tweak the trim a little when hand flying the aircraft to make it smoother.

Thanks

Hi,

Sorry, I don't know what controls the trim. As I remember FSAviator set the full range of the trim to handle all known situations, and if you make it "smoother" you have to limit the full range of the trim. This could lead to situations where you run out of trim.

Hi Tom
I probably haven't worded this all that well. What I'm finding is that when hand flying the VSI tends to jump up and down more than I would like and you have to keep adjusting with the yoke. On a number of other aircraft I found the same problem and altered a "pitch" line in the .cfg file which has fixed the problem for me. I remember you pointed me in the right direction the first time a few years ago.

The thing is that I can't find a similar line in the Convair .cfg file. Just wondering if I'm looking in the right place.

Thanks
John

Oh, you want to change the flight dynamics to compensate, got it.

I would first try this one:

[flight_tuning]
pitch_stability = 1.0

I might change it to 1.2 or even 1.5

John,

You might also want to look at the options in a complete [flight tuning] set from one of the default aircraft. Normal setting is 1.0 (100%) for all lines but apart from Tom's suggestion for stability I also reduce the "elevator_trim_effectiveness=" setting because my controller (ancient sidewinder) isn't good for fine adjustments to trim.

Another area that can be different according to your controller is options/controls/sensitivities. For the big props I prefer to use sensitivity 75%-zero null zone for ailerons and elevators, 50% both sensitivity and null zone for rudder. It's a compromise between flight and ground handling. The point is to stop it handling like an Extra300!

Hi Tom
That is exactly what I was looking for. Many thanks.

Hi Tom
Have gone through the .cfg files of each aircraft but cannot locate the line you mention. Is it somewhere else or do I need to enter the line myself?

They are not always present in every cfg file. In that case you need to add them to the existing flight tuning section, or if not present add the heading line as well.

I always get them from the default 737 cfg file, which has a pretty complete set.

Thanks Tom

Understand. Will see how I go. Again thanks to this Forum, I have learned something new.
