Not much, they are usually short coupled so ground handling isn't as good but a few flights will get you used to that. Some will stall very fast when flying too slow in a bank. A lot depends on the plane itself. You would have to name the Bipe you are thinking of flying to get more then a general answer. I find them easier to land because they slow down faster and have a lot more lift. The easiest one I have ever flown is the Tiger Moth, the best stunt plane was the Ultimate. Most of the ones I have built were of the WWI vintage and they were very easy to fly other then the ground handling and that depended on the coupling of the plane. Setting up the incidence is the hardest part of the build but a good incidence meter takes care of that.
