Top speed 295? Throw in dive speed with great dive brakes I bet this pic can engage at over 400 mph with little problem. I would bet that once its dropped ords and is light with those 20mms I bet this bird will give a better accounting then Cobra in his A-20. I bet it turns better then the Dora at low speeds, maybe even outturns the 51. I think history notes that the Dauntless was effective but pretty risky. This bird far more able to handle itself. By the end of the war the latewar F4U-hogs could carry as much firepower and the jabo came to the Pacific.
In any case, I think at some point this bird is added.
