I found a plane that will flat spin in G2!
 

Here is a recording of an Extra doing an upright and inverted flat spin on Real Flight G2. Flat Spin recording You can find this plane on the Real Flight swap page. It's the Extra 330L 33% Competition.

Yeah, the 330s does flat spin fairly well. It actually feels like it is flying in a tight circular arch. The AT6 Texan will spin in a stalled condition inverted as well as the plain old Extra 300s done up in IMAC style (don't know who did that one).

The new Edge 540T also does as well as the 330s.
