Some quick performance test data....
Speed at sea level, clean, no ordnance, 25% fuel: 315 mph WEP
Speed at 7k clean, no ordnance, 25% fuel: 336 mph
Turn radius, clean, no ord, 25% fuel, full flaps: 515 feet (81 mph stall speed)
Corner Speed as configured above: 199 mph
Climb, clean, no ord, 25% fuel, WEP. About 3.1k at SL, 2.9k @ 5k. Didn't test this, just general obervations.
Conclusions: Reasonably fast at low level, with good climb rate below 10k. Good low speed turning ability, clean and with flaps. Slow roll rate. Above 350 mph, controls are extremely sluggish. Watch your speed dive bombing or you'll be making holes in the ground. To maneuver for combat, you have to get it slowed down. It behaves very much like a Boston in that respect. Below 200 mph, maneuvering is great, except for that very slow roll rate. Better outward vision than A-20G, but the A-20 handles better above 200 mph.
