Default Plane for my K&B 7.5

Anybody got a suggestion for my ducted fan K&B 7.5 engine? It's basically a souped up .45 with a rear exhaust and a tuned pipe about a foot long. I think I'd need a delta shaped airframe with a dual rudder to clear the pipe. Guess I'd want it big enough to see, but still be small enough reach a high airspeed. Of course guideance concerning the right size prop might help too. Any suggestions?

Regards,
Jon
