How to modify aircraft steering

Recommended Posts

Guest cfh2k3

Could someone please tell me how & where to modify the steering ability or perhaps it's called turning radius?I downloaded a third party plane that will not properly taxi because of poor turning ability.The BERIEV BE-103 Light amphibious twin.I already replaced the default panel with the King Air default panel.And changed the brake cfg to the King Air brake cfg.But unless the taxi is other than straight-line, ???

You need to look at the aircraft.cfg file under contact points. The steer angle of the nose gear may be set too low. Below is an example of the default B747 and you can see it has a 70 degree steer angle.Hope this helps,Bob[contact_points] //0 Class <0=none,1=wheel, 2=scrape, 3=float> //1 Longitudinal Position (feet) //2 Lateral Position (feet) //3 Vertical Position (feet) //4 Impact Damage Threshold (Feet Per Minute) //5 Brake Map (0=None, 1=Left, 2=Right) //6 Wheel Radius (feet) //7 Steer Angle (degrees) //8 Static Compression (feet) (0 if rigid) //9 Max/Static Compression Ratio //10 Damping Ratio (0=Undamped, 1=Critically Damped) //11 Extension Time (seconds) //12 Retraction Time (seconds) //13 Sound Type //14 Airspeed limit for retraction (KIAS) //15 Airspeed that gear gets damage at (KIAS)point.0 =1,-25.0,0.0,-17.5,1000.0,0,2.0,70.0,0.5,3.5,0.900,9.0,8.0,0,220,250

You are correct. You count over to the eighth value, each one seperated by a comma.If you are still having problems, how are you controlling the steering of the airplane...using a joystick or the numbers on the keypad of your keyboard? The joystick may need to be calibrated if your using that means. If you use the keypad, I believe that each time you hit the key the nosewheel turns 1/16th of the total steering angle (I read this value somewhere else and I believe it is in 16th but I may be wrong.) or about 5 degrees each hit.

I have a MS FFB2, and have no problem with other planes like this.I changed the 82.0 to 90.0 which seemed to help some.Then tried 100.0 at which point when it didn't seem to help I began wondering if I was using the right sequence number (eight value).I've about given up on this plane though. My frame rates really suck with this one.Thanks for the help.
