Adverse yaw is a side effect of aileron use, countered by rudder input. The rotational force thats needed to move an object about an axis is called torque. The simplest formula for torque is: Torque = F x L L is the distance between the object and the axis of rotation, also called the moment arm. What Is an Aileron?

The principle is the same whether the aircraft gets thrust from propellers or jet engines. A propeller forces air backward, while a jet engine ignites a mixture of air and fuel to generate hot gases that eject backward. In jet engines, increasing throttle increases the fuel flow, producing more exhaust gases that can be flung backward.

The Aerostar is the product of famed aircraft designer Ted Smith, whose name is attached to such classics as the A-20 twin-engine bomber and the Twin and Jet Commander lines. But when it all comes together, its an impressively capable go-places machine with a flying experience more like a small jet than a light piston twin.

Another advantage of the counter-rotating props is the elimination of torque roll. This is the tendency to dig in the left tip float during takeoff while countering engine torque. 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).
