RE: Bipe suggestion.
The Goldberg Ultimate ARF.
It flys very well, mild or wild. Lands relatively slow. It's easy to field assemble. It permits the widest range of flying styles of all the planes mentioned so far. The Saito 91 is more than enough engine for the plane.
By the way, I fly bipes more than any other type of plane, and the Ultimate by any of the manufacturers is a good flying aircraft.
