Lots of good options out there.

My personal first choice is the Evolution .46 or Evolution TPS (it's a .45 with a funky prop. toss the prop, and use a standard 10x7 or 11x5).

Second choice is an OS .46FX. (but not the AX or LA)

Thunder Tiger .46 is my third.

There are lots more that are good too, and I'm sure a lot of people will post their personal favorates.
