OOOH 18 50 cal's and after she is light it will turn inside a 109! 
Would make a great light perk bomber.
If you read the below section, it's taken from the A-26 flight manual. As you can see, it will not out turn a Bf 109.
The following maneuvers are restricted:
A) All aerobatics
Looping, spins, rolls and violent stalls are prohibited. The airplane has a wingloading of 60 lbs. per square foot normally loaded with flaps up. It was not designed for air circus maneuvers or student aerobatic training.
B) Vertical banks
Remember the A-26 has a high wingloading, and your stalling speed increases with your rate of bank. For example, at 32,000 lbs. gross in a 60 degree bank with the airplane clean and power off, your airplane stalls at 192 mph (42% higher in a 60 degree bank than in level flight).
All these maneuvers are prohibited chiefly because of the high wingloading of the airplane. Take the airplane's designers and your instructors word for it. Don't experiment.
If you have evidence that can confirm without a doubt that an A-26 can out turn a Bf 109, please post it.
The workings are there somewhere. Was my favorite ride in AW.
People that fondly remember the Invader from AW I think will be in for a rather big surprise if the Invader is ever added to the plane set. What made the Invader so good in AW was not the plane itself but the rather grossly inaccurate AW flight model that allowed the plane to perform far better than it was able to in real life.
ack-ack
