I only have 2 flights on mine because of the weather but it harrier'd and elevator'd very easily only stuck the nose up for a bit due to a brand new engine but torque rolls seemed very stable. Should be a ton o' fun once I get used to it.
I oversnapped it the first few times, you have to get off the elevator pretty quick, Knife edge is very good, only a slight amount of pull. I noticed no roll coupling
