A good first bipe is the Sig Hog Bipe, but it's a kit not an ARF. That was my first bipe and I still have it. It can do stunts(knife edge,snap rolls & more) and can still be a relatively gentle plane and it floats real well. I have a O.S. 91FS in mine with a 14x6 prop. The plane has a long moment so it's not a hand full on the ground as opposed to a plane like the Pitts Special(short moment). There's a couple of Tiger Moth ARFs out there that I'm sure are gentle fliiers. There's also the Ultimate Bipes that I think you should'nt go to from trainers, they're very responsive and stall a little easier but once you're good with bipes they're a blast. Well that's just one man's opinion. Good Luck.
