rc rock

i need electric trainer that will be able (with some upgrades to do some simple and intermidiate aerobatics) i was looking at the hobbicco nexstar and the e flight apprenticce 15e.
i will be using lipo packs and the difference in price is not a problem. i'm leaning towards the nexstar cause it's bigger, and is not constructed of foam.
i'm a rc car guy so take it easy on me with the plane terminologgy
