It thought that as well initially, first post I go into it. Upon further research a surprising number of aircraft stored fuel in the outer (outside the fold) panels. So it WILL reduce it but by how much is yet to be seen. A good example would once more be the F9F-6 and -8. As I have said in other threads the thought of storing a bunch of fuel outside the fold gives me the hives!Looking through the sacs: spotting 80 F-11 on an essex class, vs 81 F-8. The wingfold is very far out; moving inward will reduce the fuel cells. Larger wing will not help there....
We have discussed in the past how the aircraft folds up and its dimensions.. in short in either the version that is my mock up or the Grumman 98-L your wings will be 17 feet or less and the length after the RN nose is applied about 40 feet. So about as long as an A-4 but not as wide.. so the A-4 spot would be closer to accurate.
