Peter, David, Just to avoid misunderstanding, by mentioning other "normal" model in the group build, I mean just those are made starting from a kit, whit or without all the usual range of aftermarket, I find ver appropriate for such kind of group build, to create a full scene of the movie, and not to be limited at an aircraft, ship or tank.
Unfortunately I' m the first not to follow my statement, since I will partecipate to the GB, with a kit: the Savoia S.21 "Porco Rosso" (which means "Red Pig"for those do not speak Italian.)
