Of all the planes on the list, I would recommend the Tower Hobbies Trainer 40 RTF package for your dad. It's a good flying plane (trust me, I've trained plenty of pilots on it) and for your needs it's a great value. You can get the plane, engine, and radio for $254. You can find it here: [line]http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXCXF4**&P=ML[/link]

P.S. I'm a bit partial to this plane as it's the plane that I learned to fly on. And after 11 years I still have it too. Good flying little trainer.
