If you want a
really good motor the Actro 60-140 would have been my choice, no doubt:
http://www.actro.de/de/inhalt/actro-60.htm The best ESC for this is propably Jeti adv 90.
The Actro motors are in the upper class, runs cool and you should be able to swing a 28-30" propeller with ease.
Battery: 2x FP EVO25 5S5000 in serie.
As tigerdude say: expensive. But nice gadgets.
Soon 50 myself, but have never thought of not being a kid

Flown for 31 years, and it still is a good hobby.
