Just can't go straight

Recommended Posts

I've searched and realize this has come up several times but is there any setting in a cfg file that will help me taxi straight?With 0 wind and weather and no control input most of my planes want to turn left then I over correct and take a snake-like path down the taxi way. I've tried calibrating the pedals (CH products) and increasing and decreasing the null zone to no avail.

The force of the motor is doing this due to the direction they rotate.

You can also reduce your P-Factor and Torque sliders to zero on the Realism options. This ought to help you keep straight until you can strike a balance between realism and how your game controllers work. Talidraggers are the hardest aircraft to keep moving in a straight line, so you always need to have good rudder control.Jeff ShylukSenior Staff Reviewer, Avsim

Make sure they aren't moving when you set to null zone. I had a terrible problem with mine which were causing the very same problem you describe. Don't speed through the calibration...you have to wait a minute or two to see the sliders start to creep.This is actually not an uncommon issue...while trying to figure out what was going wrong, I searched the CH Forums and found several posts like the one below...http://www.ch-hangar.com/forum/showthread.php?t=4090When I emailed CH Products tech support, after assuring them I've done everything to correctly calibrate, here's the response I got:"That is not caused by Control Manager, that is control manager revealing a problem with the Z axis potentiometer. That is called drift."So, check your calibration sliders, specifically the Z axis slider. If it moves at all after calibration, there's your problem.CH was actually pretty good about replacing them (but they were still under warranty).

Good catch! I'm looking to upgrade my pedals soon, that's something to watch out for!Jeff ShylukSenior Staff Reviewer, Avsim

Here's what cured it for me: Adjust the sensitivity of the pedals (in the Controls settings for FSX) so that they're as insensitive as possible. Then you won't be swerving all over the runway with touchy pedals. NOTE that, contrary to all common sense IMHO, this means moving the sliders to the far RIGHT. Once I realized that the sliders were backwards to what I expected, I had no more problems. I have the CHproducts pedals, too.-theProf

I've found that even a small null zone creates a "pull" to one side. I use CH Pro pedals also. It appears that FS doesn't add the null zone on either side of the centerpoint. It appears to shift the range of the axis from one end. And they are very sensitive as well. The pressure to keep straight on taxi run is very, very slight. That does make it difficult to always stay centered.This is all FS specific. They work very well on other sims.
