Hi FSDT. So the regional jet im using is the Posky Embraer 145XR. Maybe its too small for the trucks?
Most likely. They have a constraint requiring a wingspan of at least 22 meters. The ERJ 145 is 20, so it won't be used.
You might *try* changing this in the SIM.CFG for the Deicer:
condition = %(wingSpan)f > 22.0 ( change it to 20 or 19 )
then remove this folder before starting the simulator:
C:\ProgramData\Virtuali\Couatl
And see if they can still fit without issues.
