I changed some things on my settings and I don't know how to fix this. George Clark

Contact Points, George! Basically, for each contact point there are 16 parameters which describe the behavior of each point. The following numbers are from my MD-80 aircraft.cfg file: yours should be the similar, so you might try playing with number 3 you will find the right number.I've identified the nosewheel in bold, for you. // Gear-------0-------1--------2----------3----------4---------5-------6--------7--------8-------9-------10-------11-----12-------13-------14-------15nosewheel:-point.0 = 1.000, 65.978, 0.000, -7.502, 3500.000, 0.000, 1.080, 70.000, 0.800, 1.563, 0.500, 7.000, 6.500, 0.000, 300.000, 300.000 Left(?) wheel:-point.1 = 1.000, -5.971, -8.448, -8.910, 3500.000, 1.000, 1.750, 0.000, 1.000, 1.500, 0.500, 8.000, 7.500, 2.000, 300.000, 300.000 Right(?) wheel:-point.2 = 1.000, -5.971, 8.448, -8.910, 3500.000, 2.000, 1.750, 0.000, 1.000, 1.500, 0.500, 8.500, 7.000, 3.000, 300.000, 300.000 [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 Ratio10 Damping Ratio (0=Undamped, 1=Critically Damped)11 Extension Time (seconds)12 Retraction Time (seconds)13 Sound Type14 Airspeed limit for retraction (KIAS)15 Airspeed that gear gets damage at (KIAS) You've altered the nosewheel contact point. Now you know how to reset it.

Here is the section copied from my aircraft cfg for the 172 (SP2). I think it is default as i don't rememeber ever changing them: [contact_points]point.0 = 1, 0.90, 0.00, -4.09, 1500, 0, 0.5, 22.0, 0.25,2.5, 0.7, 0.0, 0.0, 0point.1 = 1, -4.70, -4.50, -4.01, 3500, 1, 0.5, 0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 2point.2 = 1, -4.70, 4.50, -4.01, 3500, 2, 0.5, 0.0, 0.3, 2.5, 0.7, 0.0, 0.0, 3point.3 = 2, -3.90, -18.0, 3.00, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 5point.4 = 2, -3.90 18.0, 3.00, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 6point.5= 2,-20.23, 0.0, 0.30, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 9point.6= 2, 1.48, 0.0, -2.17, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 4point.7= 2,-22.80, 0.0, 5.83, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 7point.8= 2, -4.90, 0.0, -2.00, 1800, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 8max_number_of_points = 21 Hope this helps, IAN

This is a well known fault in the original DVD. It has to be rectified everytime you reinstal FSX. Under [contact_points] in the C172 aircraft.cfg file alter the 3rd number from the left as follows: point.0= change -4.09 to -4.20point.1= change -4.01 to -4.02point.3= change -4.01 to -4.02
