I've just released a new aircraft. It is the Panthera from Pipistrel. You can download it from github: https://github.com/urbu/fg-aircraft-panthera/archive/master.zip
It is very basic most of the instruments aren't working yet but it is flyable.
The only issue is the fdm model. The plane can fly but it doesn't reach the desired speed I think that the drag is to big. I created the fdm model using aeromatic: http://jsbsim.sourceforge.net/aeromatic2.html If someone has any idea how to solve the fdm problem please write a reply.
This is the link to the home website of the real aircraft: http://www.panthera-aircraft.com/
I will try to get out a new version with a lot more sistems working in a few months depending on how much time I will have.
