You need to make sure you don't add or delete characters from the MAS file as
that info is in the header. You can alter values and it works just fine.
Examples:
mass=(1145.0) changed to mass=(1005.0)
throttle_rpm_ratio=(9622.2) changed to throttle_rpm_ratio=(3621.3)
antipitch_susp=(1500.0) changed to antipitch_susp=(2560.0)
CSINSIDE_ENGINE_REVVED=ENG2IC.WAV
change to CSINSIDE_ENGINE_REVVED=ENG2IQ.WAV
and add a wav file to the both the 22k and 11k sound directories.
