The last CVS Noratlas and PBY6-Catalina are supposed to fly with CVS FG with
the new JSBsim.
However i did not test with the following last update:
Update of /var/cvs/FlightGear-0.9/source/src/FDM/JSBSim/models/propulsion
In directory baron.flightgear.org:/tmp/cvs-serv17217/models/propulsion
Modified Files:
FGPiston.cpp
Log Message:
Sync. with JSBSim CVS
Index: FGPiston.cpp 14 Aug 2008 14:16:50 -0000 1.9
I must look at it. May be the engines will want a new update.
However if you intend to look at the particle effect , only the Catalina has
it , and , only with .osg files.
I have not yet included any <particlesystem> .xml.
