I don't think the switch from the 51-B and 51-D will be an issue. I flew Pony-D's, 47's, A-8's, and all kinds of other guns-a-go-go birds, never hitting a damn thing.
But when I up a G6 or an FM2,
somebody's gonna go down. And it ain't me.
(BTW, I love when spit dweebs try to out turn an FM2. Their rear stabs fall off so nice.
