I'd have to go check exact property names, but you can set the lon/lat/elev of the tower view to anything you like, then placing the tower vantage point anywhere you want. A 3d modeller could create a little flat rendition of their R/C model field as a single object (or collection of objects)

Hi, Curtis has already hinted as to how the following may be done with his remote FDM. To my mind flightgear can be broken down into distinct plugin modules. There is the FDM, the external world visualisation,the cockpit input and output (ie joystick,pedals,switches and displays) and possibly

Hi, I'm about to commit an F-18 newly created by Fabrice Kauffmann. I haven't had a chance to setup a PLIB branch here and only have the OSG head. If I commit this to the OSG branch, would someone out there be willing to do the honors of committing it to the plib branch? Thanks, Curt. --
