PARE: Power idle, Ailerons neutral, Rudder opposite, Elevator forward. An aft center of gravity increases flat spin risk. A flat spin happens when the center of gravity shifts too far aft (toward the tail), and the aircraft’s rotation becomes more horizontal. Rudder: Full opposite input to the spin direction.

Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. Doing so provides more lateral stability since the aircraft’s Center of Gravity (CG) lies below the wings. Most commercial and general aviation aircraft are designed to be dynamically stable.

Adverse yaw is a side effect of aileron use, countered by rudder input. In recent times, composite materials have been introduced for flight controls even in small general aviation aircraft. Fly-by-wire is expensive, so you wont find it on most small general aviation aircraft. This is where the rudder comes in.

An elegantly simple rope system inside the fuselage raises and lowers the Gweduck’s water rudder mounted inside the base of the main rudder (right). The only unconventional thing I noticed (as did the folks in back) was the rudder has a dead spot mid-travel. I think I’d have figured out the trick in another couple hours.
