IF you really want one, design it yourself.
I was looking for the same thing last year and didn't find anything either, so, i built one myself. The result was a Edge 300 as I call it, Or, " little sum b&%ch" as a good friend calls it. The equipment I used was a GWS power pack, 10amp speed control, extra servo and $22 GWS motor/drive. The forth plane weighed in at 9.25oz and including everything less Tx. My original goal was to make it inexpensive and I think I accomplished that. At $200 for everything in the plane.
If you are interested in seeing it fly, check out minnesotarc.com, under the movies section.
The little plane is capable of doing Knife edge, flat spins, climbing flats, hovering, torque rolls, and many others. I am trying to have something ready for Toledo this year, kits maybe, or at least the very least, completed plans.
