Hello all,

I 'm new to FSX and this site has benn helping much.

After too weeks of tweaking and changing .cfg files, I finally been able to run FSX with beautiful graphics in a decent frame rate, without making the computer runs too hot while doing so.

 

I'm flying around and doing Rob Machado's lessons, but there seems to be this annoying problem with the Cessna 172, that it always banks left, in a fairy high rate (something like 10 degrees of bank in less than 10 seconds).

From what I could gather from other posts, there's the problems of gyro effect, p-factor, wind and payload configuration. But with everything set, the problem still occurs.

And I don't have the same problem flying the Piper Cub, for instance.

So, I would like to know if there's some tweaks in the flight model file one can do to solve this problem, or if the solution is to leave the realism bar to the left.

There is also the issue of calibrating the controls, as well as fuel imbalance...

 

If it works fine with the realism bar on the left, I'd suggest you use that, or correct

with the flight controls to keep the plane level.

 

The FSX C172 flies OK, so it is not a flight model issue..

I had the same problem. For me the fix was reducing the realism settings a bit. I usually don't do this, but inthis case I had, because in my opinion the plane is unflyable if I can't take my hands form the joystick a single second wiithout having to fear that the plane will crash into a mountain.

Bert,

Thanks for the help. It sure helped a lot. I increased the null zone on my rudder pedals and it became a lot more stable.

 

OE-LAT,

As said above, change yor controller settings. It helps. I also disabled the mouse yoke axis. I believe it was interfering somehow.

Also, I changed two parameters on the Cessna 172 aircraft.cfg file:

 

[flight_tuning]

 

roll_stability = 2.0 //added new stability parameter to try to stop the left bank tendency on Cessna 172

yaw_stability = 2.0

 

This, coupled with the settings made, really helped. I still get some drift to the left, but not as same as before. It is much more stable. Since most single propeller aircraft will have a tendency to drift with time, I believe now it is in an acceptable level. It compares with the behavior of the Piper Cub, regading banking and heading keeping.

Moving all sliders to the right doesn't always make the aircraft behave more realistic in FSX. It is all relative to the aircraft you are flying and how that aircraft interacts with the FSX flight model. RealAir for instance advises you to reduce some of the realism settings to make their aircraft behave more realistic.

Thanks Simmerhead. I've read in a book that the best setting for Flight Simulator is the Medium setting.
