Carenado released their Baron B58 for X-Plane 11 yesterday, and the aircraft is a fully native version for X-Plane 11.
SimCoders have today confirmed that their Reality Expansion Pack (REP), which already exists for the older version, will be coming to this aircraft. The current REP does not work on the new version. As such, a new REP for this aircraft will be released at some point, and existing customers will receive a discount.
No release date was provided, but it “should be available rather soon.”
The Reality Expansion Pack currently sits on version 4.0.3. Version 4 brought with it a new economy system – more details of which can be found here.
