How many examples can you think of?

avbug -- I'm not sure where you are coming from with the two half-engines. The O-2 (Cessna Skymaster) has a difficult time flying on one engine, but the OV-10 is significantly more powerful. The wingspan is 40 ft. Your stamp box must be pretty large. The OV-10 is great at low levels because of its visibility and maneuverability. I'm not sure where you are coming from here. How much time do you have in the OV and why do you dislike it? I flew it and, like most people I know, enjoyed it a lot for what it was--a high performance twin turboprop, but not an F-15 or F-16!

Skaz -- There is a very active OV-10 pilots group--guys who really enjoyed flying the OV-10. Try http://www.ov-10bronco.net/ for more info on the OV-10. They would probably have the best leads for trying to buy a civilian version. Good luck.
