I think it may be due to the wind. With all the aircraft I did, which all used the YASim FDM, I noticed that while sitting on the runway, and if left alone for long enough, the aircraft would slowly weathervane in to the wind (I was normally using fixed i.e. non-METAR weather scenarios for FDM tuning, which only had a windspeed of 3 kts at ground level, and as I used this for all aircraft it became noticeable that the weathervaning was always at the same low rate and in the same direction). The aircraft wouldn't move up or down the runway, at least with the brakes on. This suggested to me that the slippage problem only related to sideways movement of the wheels. Have the people having bad problems with this tried increasing the values for the <sfric> & <dfric> gear sub-elements?
