Make sure that in the aircraft.cfg file you have a section
[GeneralEngineData]
and under that the line
min_throttle_limit=-0.250000 //Minimum percent throttle. Generally negative for turbine reverser
and in the
[TurbineEngineData]
section there is a line
reverser_available = 1 //Thrust reverser available?
with 1=YES and 0=NO
I am presuming the aircraft in question IS a jet, not a turboprop, yes? If it IS a turboprop, there are a few other settings to look at in the [propeller] section.
Feel free to ask any questions you may have. I bet you get more info than you can use all at once

Have fun, fly high, far, and free!
