Planes the won't move

[JWLeightman]

Hi, Mention has been made that some planes will load and make engine sound, but will not move, and that this may be caused by trying to use that plane designed for one FMS version with a different FMS program. That has happened to me, but I have a different, related question: I have a few planes that, after changing power and control surface throws in the PAR file, the plane will no longer move. Any solutions? Thanks. Jim

There are some changes to the .par file that will cause the model to crash immediately after it's initialized. I've also had one where a change got it stuck below ground.

Make sure the wheels and collision points do not go below zero and that the height above ground is equal to or above the wheel height.

Always make a backup of a .par file before editing or download the original model again to get the original .par file.
