Some airplanes jump around and crash when loaded

[patfrank58]

When I load certain airplanes, only airplanes, not helicopters, they pop onto the screen hopping all over the runway and crash in a few seconds. I have tried to reinstall the airplanes and FMS but nothing works. The flying sub and the Pitts 14 are two of the problem planes. can anyone help? Thanks, Pat

Edit the .par files of the models you are having problems with. The WHEEL section needs to be changed. Usually increasing the breaking load will solve the problem. However, bouncing around usually requires changes in the other 2 parameters. Just change them, save the .par file, Reload the model, until its working for you.

1000 //spring constant [N/m]
10 //Viscosity [N*s/m]
100 //breaking load [N]

Thanks for the reply, what do I need to edit a .par file. I am unable to open it. Thanks, Pat

Mr. Masuoka has what I think is the best .par editor but you can use Windows NotePad or a text editor to edit the .par file too.
