C-47's? No, they can't shoot back. There is absolutely NO RISK in attacking a drone, unless can't avoid mother earth. No ACM involved at all.
You want evaluate the ability of the airplane to kill in combat, right? Not just target shoot? (Although I doubt K/D is much of an indicator of anything, given the way the game is played in the MA)
I think you need to run the numbers again, as it makes a real difference, IIRC.
I ran the numbers for Tour 7 in your "least popular plane topic", posted 08-08-2000 09:32 AM, and I quote:
"Well, what happens when we focus on Air-to-Air kills?
Here's a view of the F4U-1C vs the FW190-A5 when you remove ground vehicles and the denfenseless C-47 (simply a big, slow target) from the Tour 7 stats.
F4U-1C
Totals 2316 Kills, 1359 Killed
then subtract ground vehicles and the defenseless flying target...
against M3 36/3
against Panzer 209/123
against M16 226/102
against C47 51/6
Totals 1794 Kills 1125 Killed
k/D is 1.59
Now the FW190-A5
Totals 2093 Kills 1336 Killed
against M3 23/13
against Panzer 13/35
against M16 103/58
against C47 34/2
Totals 1930 Kills 1228 Killed
K/D is 1.57"
So I got F4 1.59 vs FW 1.57, essentially identical K/D.
Leaving the defenseless drone C-47's in, you got F4 1.64 vs FW 1.44.
Take the drones out of all of them and see how it looks.
Anyway, my point is that folks have been crying about the -1C as too "uber", a "dweebmobile", and all that other dross, using the "Sacred K/D Stats" to support their argument. At the same time the -A5 has had essentially the same K/D. THAT'S what I find funny.

Do cannons make a difference? I hope so..they make a difference in every other plane in the planeset. AH clearly rewards cannon armed planes and planes armed with 4 cannons it rewards the most. Is this news?
OK, now you come back with the standard LW reply: "well, in the F4 it's the plane NOT the pilot...in the FW, it's the pilot not the PLANE" chant.
