Beau was in if from beginning to end. It's history extends further then the 110 and Mossie in terms of where it fought. As for the MA, the Beau would do more jobs then either the 110 or Mossie.
Personally I'd fly it cause it's a low alt bird and I like it on the deck. And I've never wanted to fly the latest and greatest which is why I wander around in a 38G.
Making the Beau work in the MA would be part of the challenge and the fun.
You're preaching to the choir
I honestly don't care about MA effectiveness in the least bit, I don't think that any new aircraft will be immediately popular and even if they were it really wouldn't change anything about MA play. That's why I'd love to see aircraft like the He 111, Do 17, CR42, I153, Gladiator, MS 406 etc etc. For the sake of scenario use.
What I'm asking is, to those that say that the Beaufighter and G.55 would be successful MA aircraft compared to the Ki 43, He 111, etc., and should be added on that merit, why do you think that they would be?
