It really depends on the bipe. In general though, they aren't best for anyone close to being a beginner. I used to have a .40 sized Ultimate Biplane long before I was ready for it. I was fine with it in the air but landing was always scary. Something about keeping power on when bringing it down to the ground just seemed unnatural for me at the time. I could handle it now as long as I reminded myself to keep the airspeed up on landing. Also, when it stalled, it didn't just drop the nose gently and fly out of it like a lot of sport planes. It would stop flying and immediately fall like a brick.
