Spot on, keeping track of it is key. Things which may help are working
on a white surface or small closed area/space. If a piece springs off
somewhere.. I have found wide paper/masking tape to help find the
little piece, many times then none the tape will pick up any other
piece which may have flown off.. I think it would be tough to build
the fuselage of an F1D without boron.. I mean unless you plan on mass
producing these models, which I doubt, you will learn how to handle
the boron as well as keep track of it all.
