I am looking for some one that can tell me what contact points I need to change, and what the numbers might need to be. To get the Super Mustang P-51 High Octang tail to be on the ground like it should be. The problem is the tail is always in the air. The plane I am talking about is on pg. 121 of the Props area of FS2004. Thank you for any help anybody can give.

Below is a copy of a typical three wheel aircraft.Mind you this is not a tail dragger but that is not that important If you notice you will see 3 number 1 classes these are the landing gear. The parameter you want to change is the third one VERTICAL POSITION you might have to change positions 8;9;& 10 as well each parameter is separated by a comma. You will have to experiment to find out which entry is the tail wheel. And mind you none of this may help if the weight and balance is set wrong that could be the problem. But try the contact points first.
Cool

//0 Class
   //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

Hi Vid.......sorry not to have answered 'fore now but been a bit busy and it was a funny old contact points section ..what with all those zeros and all.........anyway if you are still interested then make a back up copy of your aircraft.cfg and then change the whole [contact points] section to this below. (The whole thing).........copy and paste would be best or you might end up with a load of typos Wink

the pic shows what it did for me..........commoner Wink

You are right about that one Zaphod.

Commoner works his magic and saves another plane from the junk yard.lol Grin

Commoner thank you so much for the work you have done here and for the other problems you have helped me fix.

Also I want to thank garymbuska for his input also, and to all the other simers that have helped me a big thanks goes out to all of you.
