I'm trying for weeks to add a quadrotor model in flightgear without success. I tried your tutorial : http://wiki.paparazziuav.org/wiki/AR_Drone_2/Flightgear , I made the ac files and tried to make the XML files but unfortunatly it just didn't work. (I'm not an expert in flightgear :( )
I would very much appreciate if you would share the sources with me. Do you think it's possible ?
