First of all, drones will fly until they are blown up, as they don't seem to have to conform to the laws of physics. Have you seen the way they pop up to 150ft at like.. 40mph?
I can also tell you from experience that the Lanc will fly without wings (quite well actually). Yes I'm sure this isn't realistic, and probably is a bug that should be addressed... but it's still fun to land them that way.
