How about a combat corsair or mustang?

You do have flying experience, right?

If you can go slightly larger than 46", I've heard the Phoenix Models Sonic is a good aerobat in the .25 size.

EDIT: Also, the DX5e and AR500 are both full range radio and receiver. So you don't need to go larger. This combination will fly 95% of the models available.
