DS2:Scratchbuilding a dropship

Has anyone attempted scratch building a dropship (a la the big GZG one)?
 I
can't afford the commercial thing and was wondering how one would do it
-
balsa, stockcard, foamboard??

I tried making a card template over the w'end and it was a big flop.  I
could cut it accurately enough using thick card and then had to fill in
the
gaps using artistic medium.  In the end it looked like a really bad 1st
year
fine arts student attempt at sculting.	very dissappointing.  Any ideas
appreciated.

cheers
