The key is to force them to maneuver as you dive out, as the Frank does begin to experience control heaviness as speed piles on (testing offline, she starts to feel heavy around 375-400mph) while the Corsair retains excellent authority well past that. A diving spiral to the right is especially effective, but either direction should do the job. Roll until he's out of phase and you can lose him on the pull-out while he's struggling with his controls.
