30 ounces is appr 900 gram...? AUW?

For good acro a brushless at 200 Watt (at least) will make it fly. 250 Watt and you are sure to have joy!

AXI is a safe choise, not the very best but good quality for most pilots. Your plane is a typical 2808-size I think, and I like low kV-motors since they swing bigger props at lower amp-draw (my personal taste). Which means a 2808/24 is my advice. APC E 10x5 prop would keep your amperes below max (appr 22 amp at 3S LiPo), if your battery keep up with the load! Will give you verticals, but not enough for hoovering. A slim prop like Graupner CAM 10x6 is propably the perfect match for max effect, still below 25 amp. And as mentioned before: the battery have to be able to deliver the juice!
Of course there are other motors, it is a lot about what you are used to. I have no idea about E-flite, not a known brand to me (although I have one...) If you like xtreme quality take a look at Plettenberg, Actro and Kontronic.
