As with any AH bird, there are those that drive the 51 and those that can really fly that thing.
You'll know when you run up against a great 51 flyer because he can fly it slow, knows how to use the flaps and can do things with it, the usual go 500 MPH, straight, hose everything and run, 51 driver can't.
Same with the Jug pilot, or any other AH bird.
It's those players who don't know how to fly the 51 or any of the high kill birds that give it the bad name because it's a forgiving bird and lets face it, when you come in at light speed into a pile of red, point, shoot and run, you are bound to hit something.
That applies to the guys who do that with LA7s, Spit 16s and N1Ks as well.
Don't blame the plane, blame the folks that give it the bad name.
personally I kinda like getting low and slow in a B Pony from time to time. Makes for a fun challenge.
