Thanks for the input guys, I'm aware that the Falcon was designed by John D'Ottavio - hence the JD.
Apparently Tom found a number of discrepancies with the MAN plan, and revised it as per John's original wing rib templates and dimensions taken off the the F86 (which is a Falcon in disguise).
I already have the plan for the MAN version, but I really don't see much point in building it if it's "wrong" - or more to the point not representative of JD's original.
