As the saying goes, you ought to learn to crawl before you learn to walk. In this case, going from a foam lightweight to a 37% large scale is a tad bit much. And, as already said, I don't know if anyone would buddy box with something that is that expensive.

Move up slowly. Get a good low wing, glow powered, performance trainer and fly that for a while to get the sense of the larger than foamie electric models, then once comnfortable, perhaps a good 120 size glow or gas, then once competent with that, perhaps move up to something large.
