241:: the blades fold forward like spears to minimize drag when the engine is off. This is in contrast to other motorgliders which mostly either store the propeller inside the fuselage, or merely feather the propeller blades. The Carat's propeller is opened by the centrifugal force on the turning blades, working against a folding force provided by a gas damping spring mechanism. This folding mechanism has the advantage of simplicity, but it means that the engine can not be windmill-started if the battery is flat. Because of the forward pointing blades when the engine is off, the Carat cannot be towed aloft like traditional sailplanes.
