Any 2 stick/4 ch surface-freq radio could be drafted into controlling 2 props. You can also spend big bucks on a Robbe Marine with nice twin sticks, or an old Ace Commander.
IMHO, its not worth it on a destroyer, the long hull makes twin prop steering less effective. I find mine to be very maneuverable without it, when using the kit's twin rudders (which aren't correct for the vast majority of Fletchers).
