I have a Great Planes Ultimate Bipe. It is one of the best planes I have ever owned.
I actually still own it and bought a second one when my receiver antenna failed and I crashed. It is a very gentle, easy to fly plane and does not tip stall easily. There is a massive thread on it under the 3D forum. Yes it slows down when you take power off but it is not abrupt and makes landing very easy. I find it way easier to land than planes that hold on to their energy. It can do 3D, I find it struggles fighting a torque roll in a hover. The ailerons in a Bipe are not aligned with the thrust of the prop. If you look around you can find them used for great prices.
