Yes, you can deadstick a bipe, but you have to keep the nose down to maintain airspeed. It might include having to land downwind if you are up-range when the engine goes out. Also, one needs to be very comfortable using the rudder for turns and applying SLIGHT opposite aileron to keep the wings level during deadstick course corrections. This is the biggest mistake I see made with deadstickspeople gettting close to the ground, airspeed is decreasing steadily, and they want to make course corrections with the aileronswrong!!! too much drag and a sure way to stall. These are all things that can be learned with a second airplane like a tiger, four star, or (possibly) cub.
The ultimate series bipes are not very short coupled like cubs, so ground handleing is much better. However, some bipes are short coupled, and ground control can be very difficult.
