Twin 4
The Swing development team spent a year fine-tuning and testing a new tandem glider before they were satisfied with the result. All of the standard requirements for a tandem glider have been satisfied. The Twin 4 received LTF/ EN-A classification from the DHV for a weight range of 140kg to 220kg without using the 8cm long trimmers. The Twin 4 is reportedly a pleasure to fly at the upper end of the weight range and also at the lower end because of its (nearly) “solo handling”. It was even flown with a load of only 110kg to make sure that the entire weight range permissible can be used effectively. Only “big ears” with open trimmers received LTF/EN-B classification.


The high arc technology was also used successfully for the Twin 4, making the canopy weight is only 8.6kg. A lightning flash design adorns the top surface of the Twin 4, while the bottom surface has been kept completely white so it can be used for sponsorship. In Germany, Austria and Switzerland, Swing also offer the Twin 4 to commercial tandem operators.

The first feedback:
"Every time we made a test flight, it was a really effortless pleasure to launch on the TWIN 4! Whatever the launch area, whether tight, flat or tricky, we never had any problems! The very clearly arranged line design meant that we didn’t lose any time having to sort out lines. Brilliant design Michael!"
