The Akagi from Hasegawa is atleast 15 years old ( its in all my old catalogues dating back to 1990 ) I haven't build it so I can't tell you if its good or bad but I have never had trouble with Hasegawa. Just because there is room for batteries and motor doesn't mean its a bad kit many of the old kits from Tamiya had the same features, the Centurion tank had it but its still a great kit. Just go ahead and build it, maybe someone in the ship forum can help you.
