If I can turn fite a fiter in my b26
Any fighter should win this fight. The fights you win doing it are not testimony to your skill, they are testimony to the lack of skill on the part of your opponent.
While wing loading isn't everything, it is a crude measure and the A-26's wing loading is very high.
Didn't the engine nacelles give it poor visibility? Iirc wasnt it a pig to fly?
I don't know about it being a pig to fly, but yes, the engine nacelles to block the visibility to the sides. That is, if I understand correctly, the reason it was rejected for service in the Pacific Theater in favor of keeping the A-20s in service.
