A single propellor aircraft exibits a left torque on takeoff and climb due to P-factor. I was wondering if in FS9 they use a yaw trim input to simulate P-factor. The model I'm using correctly simulates the p-factor up until aprox. 80 knots. Then when above 80 knots the aircraft actually tries to roll right as if the p-factor was applied to the air file in reverse to the higher speed table used. Which tables are responsible for this?Also in aircraft like the Yak 52 with "backwards" turning engines, we would have to simulate right torque p-factor on takeoff and climb.Thank you for any assistance

You could do this in FS2002 by adding a line in the aircraft.cfg {Propeller} section:{Propeller}Rotation=-1I've not tested this in FS2004 but I guess it still works.boneshttp://fsaviation.nethttp://www.precisionmanuals.com/images/forum/ng_driver.jpg
