Performance slot for a pure Air-To-Ground Scythe?

[LectraWyraph]

Basically: I want the best performance frame for attacking ground targets, then simply fleeing away when another aircraft comes after me. I want the best performance slot for flying away from enemy aircraft so I don't have to fight them at a severe disadvantage.

Does the racer airframe go faster than the hover stability airframe? Will it help me escape enemy aircraft easier? I've read repeatedly that the hover stability airframe gives additional speed, so I'm unsure which performance slot to choose.
