For instance, I cannot steer with my rudder pedals, it just goes where ever it wants. Applying power to take off, sometimes works, sometimes it does nothing. When it does work and I lift off, the yoke is very erratic. There is no control, most of the time if I even try to make a slight turn it completely does an aileron roll. Cool, but not when your trying to train. Horizontal control usually means a extreme pitch up and a stall.
