I'll second Radyar on the Sig LT40. I use an OS46AX with a 12/4 or 12/6 prop and it still needs a little nose weight so a .60 should be fine. Sigs kits are top notch and every Kadet I ever saw flew like a dream. Our club uses them exclusively for trainers. After a couple years wringing out my own LT40 I wanted more so I set it up with 3" by full width ailerons programed as flaperons with up to 30 degree flaps. The guys are always impressed when I do a slow fly-by at walking speed and fly it backwards or land it vertcally in the wind. An Lt40 will provide a great learning experience and years of fun. With full flaps I like to show off by taking off from one of our 7' carpet covered setup tables at the field. It doesn't even need the whole table. Program the rates higher and it even becomes a mild aerobat!
