I think I have made some good progress. First I tested the B5N2 on the Burma map. With the following entries in the classes file I was able to use the plane as a bomber:
B5N2 Burma Base
B5N2 GROUND
Then I used the B5N2 as a land based torpedo bomber on the Palau map and it worked.
When I tried to use the plane in the Coral Sea subcampaign as a carrier based torpedo bomber it didn't worked, but when I tried the same in the Midway, Marianas and Santa Cruz subcampaigns I was able to fly the B5N2 as a carrier bomber. I had the following entries in the classes file:
B5N2 CoralSea CARRIER
B5N2 SantaCruz CARRIER
B5N2 Midway CARRIER
B5N2 Marianas1 CARRIER
B5N2 GROUND
I don't understand why I can't use the B5N2 in the Coral Sea subcampaign. As far as I know, it uses the same map as the Santa Cruz subcampaign. I had the same issue when I tested the TBF1. It worked on the Midway, Marianas and Santa Cruz maps, but not on the Coral Sea map.
what to make by TBF1,TBF1C,TBM3 and TBM1?to explain me?
