The S12 comes in 3 models: The S12-SW Sky Cruiser short wing version at 21.7 m span for when space is at a premium. The S12 Twin Voyager 25 m span high-performance glider and sport plane in one package. The S12-G Grand Tourer the ultimate high- performance long-distance version with an all glass panel with twin Garmin G3X and Auto Pilot. Two instrumentation packages are available oriented to either soaring or power flying.
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.
The mid mounted Rotax turbo charged 914 F engine delivers power through a unique carbon fibre drive shaft to the Stemme-Retrac foldable and variable pitch propeller. The turbo enhances high density altitude operations.
Southern Energy Sailplanes has partnered with Bert Flood Imports, Australian Rotax distributors for over 30 years to provide quality service and reliable spare parts availability.
