> Clements says the rudder pedals are rarely touched during flight, something unheard of for most pilots, especially those who fly small twin engine airplanes.

Is this really that unusual? In the Bulldog (which is very small and single-engined) you can get away with not using the rudder at all during normal flight.

Edit: Asked a friend who knows these things, it's not that unusual for a twin engine to not need a lot of rudder, but also not a rule either.
