The PAR File - What am I looking at?

[Dale Evans]

I have Eric Scholten's translation of the PAR File which tells me what each line controls but I do not have the slightest idea of what the values mean.
When I open the Par File in Wordpad I see two columns of numbers.

0 <0>
5 <6>
1.5 <0.6>

Can anyone tell me what each column does and how the numbers control the aircraft.

If I want to decrease Rudder movement how do change the numbers? Do I have to change both numbers?

Thanks,

Version 2.7 .par or version 2.8? They are extremely different.

I am using 2.7

Only the first number is used. All other information is treated as comments.

1, The first line must be zero or one.
2, Thrust, newtons, increase = faster, decrease = slower
3,4,5, Increasing angles in radians increases control throws. Zero means no control.

Others are either obvious or shouldn't be touched unless you know what you're doing.

20,21,22 Inertia moments control how well your model tracks or whether it is hard to keep flying straight, lower numbers are more stable like lighter airplanes, higher numbers keep on moving like heavier plans.

Hope that helps!
