I don't like the small landing gear on this plane, since I have a couple of small vertical stabilizers on the bottom, if the clearance is too short they break off on takeoff (and it would just look silly to put the landing gear right on the tail).
It does get pretty slow, but it's also supermaneuverable. I find that slow turning speed doesn't really affect affect the plane, it only makes you vulnerable to missiles, and countermeasures seem to be the defining factor there, not how fast you are going. Also, the more you crank up steer factor it just causes the plane to go crazy, I played with a bunch of the other setting as well but the changes were either undesirable or negligible (though one of my other designs benefitted from having steer factor up to 18 with steer damping up to 6). Extra guns don't really help much either, which is why I ended up removing the second one (and freed up some extra points to use in the process), wing surfaces explode from one 20mm shot, and it's usually fatal if it's one of the main wings that gets hit. Also there's a benefit to having one gun far below the cockpit like on my plane: As the plane rolls, it makes it's own large cone of fire with only one gun, and it ends up spraying in wider area than it would normally.
