I would usually agree with you on this, if I hadn't recently discovered something about the La7, that likely prevents it from being a perk plane. It seems to have a rather hard ceiling, where it first loses all gains from wep, and then steadily loses engine performance. They only really like playing near the ground.
So, dont like lala's? Drag 'em up into the ether, and tear 'em to pieces. Works for me:D
