Igor the GB is for Vietnam aircraft so I don't know to what you are referring as 1/700. The ship model you are doing would not fit the GB.
I've got some Skyraiders, phantoms etc. in 1/700 and some other Vietnam era aircraft, just have to sort through the pile, thought they'd make an interesting dio. My initial idea was a crashed skyraider while another one circles overhead, although the 1/700 aircraft don't have many seems the ones they do have are a nightmare to fill in at that scale. If thats ok i'll make a thread with your permision
