I have an old Global kit "Cutlass 45 flying wing fighter" that i plan to start building. Its difficult to find much info on this obsolete kit on the web. Is there anyone out there who has build and flown this model? Any information is of interest.

Check with some of the model magazines for the people who supply scale documentation. They usually have more information than you can use. As far as the kit goes you will have to make do with what you have but the scale three views may give you an idea or two about where to go.
