The Stemme-Retrac foldable and variable pitch propeller is installed in the Stemme Twin Voyager S12 and disappears completely into the propeller dome. To start the propeller, the dome slides out and the propeller blades unfold. It takes just 5 seconds to convert from glide mode to engine mode.
A separate baggage compartment is inte­grated into the fuselage. By providing space for hand luggage, the compartment significantly expands your touring options.
An autopilot is part of the richly equipped cockpit. In disconnected mode it provides an extremely direct steering feeling, unbeatably immediate and sensitive. With its innovative electrical trim equipment, the Stemme Twin Voyager S12 puts the perfect tool for super­lative performance into its pilot’s hands.
The solid and safe one-piece canopy offers great panoramic views. The side-by-side alignment is ideal for sharing workloads, using the same avionics or simply for pure recreation—just as in conventional planes. The center-tunnel-fairing provides additional storage space for your smartphone, notebook and other onboard companions.
