It looked a bit excessive to me however, we don't have any idea what kind of stick he has or what the curves (or lack of) he had set up. I doubt very seriously that the A-4 was that "twitchy". I also don't know anything about what type of control system the Scooter had. Was it mechanical, hydro-mechanical or fully hydraulic? I do know that the Scooter had a reputation for a very high roll rate.
