I used the LA-7 when the vTards where around. Not because of their skills or numbers, but because it was quick enough to chase down vDallas who would run a the first sign of a co-alt fighter in his P-51/Dora. A few months later I found him sitting high over his meat shield in a LA-7, so I picked up a Tempest.
Ah, the days of chasing him 3 sectors to shoot him down, then have him rant on Vox/PM about your poor skills and how he will hunt you down.
Now days I fly the LA-7 out when I want to get to a fight/base defense quickly.
Oh and I will accept the LA-7 needs a perk when the Pony Bomb-trucks get an equal one. Yes the LA is a good fighter, but its short legs, 3 cannons and 2 small bombs are not enough to worry an airfield. 5 ponys can shut down a small AF, 5 LAs would have to put everything in just to kill the VH.
