I agree with Messiah. I think the biggest issue with .50s is the damage model. Damage in AH is cumulative you have to hit one spot hard and long to do damage with .50s vs cannon. Cannon have splash damage so you don't nessecarily need to hit any particular area to break something off. A perfect example is deacking with a spit vs a jug. All the spit has to do is get close to the pit with a 20mm whereas a jug has to hit the actual gun to do any damage. The damage model, I think, puts too much emphasis on convergence for .50 armed aircraft. A standard .50 cal round will penitrate 1/4" steel at almost a mile. A Jug throws about 100 of these rounds in a second. If you get caught at convergence for a 1/4 second snap shot, that will put around 20 rounds in the same area and break stuff off. Far too often, aircraft in game fly away unscathed after turning white white hit sprites from tip to tail because of the dispersment of the ammo and the lack of cumlitive damage to any single piece. Our aircraft don't have nearly the ammount of moving parts the real counterparts did. If they did, even long range shots would wreak havoc With the aircraft. Knocking out electrical systems, punching holes in coolant lines (not just radiators), breaking control cables and pullies, breaking gauges, perforating superchargers and impellers, breaking hydraulic lines, making holes in props and breaking hinges. All these things wouldn't nessarily bring an aircraft down but would seriously degrade its ability to fight. None of this is accounted for when that aircraft flies through a waterfall of .50 cal bullets. I've fired the browning several times before. I know what that weapon is capable of and AH is not quite up to its legendary standards in my opinion.
I've said it many times on range...
I want three shots at Dale's car with a .50. It might start afterwards but if it drives more than a half mile after taking those three shots, I'll replace the car and apologize for questioning the lethality of the browning armed aircraft in game.
