this is one from mamo models. I flew one that sean plummer had at the RCX show last may, and I think it was this model, although it seems it was a touch larger. It was 10 oz flying weight with hacker B20 26S and a TWO cell TP lipo pack. TREMENDOUS performance. hover/torque rolls at about 1/3 throttle, knife edge at about 1/4 rudder input, could rotate from knife to hover very easily, almost no coupling. really a great little plane.
