Hard to beat a Tiger Moth for a beginner level bipe.
The questions I must ask before suggesting a specific one:
Do you want kit, ARF or RTF?
How big is your flying site?
Will transport of a 50 inch model that is a bit difficult to assemble and disassemble be an issue? (A good one is going to require a small station wagon or hatchback car for transport... Definitely won't go in a SmartCar )
