I've been flying a F-100D by Kazunori Ito but it has a problem that it busts mach 1 at a low speed.
For example, at 25000 feet, it thinks mach is about 375 knots. It should be around 693 knots. It does scale the mach speed down as you increase altitude but it is very far off - almost by a factor of 2.
I've been through the air file (air edit), the configs and such but cannot find where I need to make the correction. I even looked into the guages and effects.
If someone can give me a clue what the variable may be named or where else to look, I'd appreciate it.
