About Ramphos

Two models are available, which can both be customized for different use according to your requirements. All our models are DULV / S-LSA certified. They can operate in windy conditions and rougher sea conditions. The frames are constructed of high quality aircraft grade stainless steel. The hulls are made of composite vacuum epoxy resin and are enforced by kevlar and carbon material. Available engines are the Rotax 503, Rotax 582 (two stroke) and Rotax 912 (four stroke).
Other features are: a composite propeller (2, 3 or 5 blades) and a Coach Wing 16.8 (quick foldable) or HZ 15S (foldable).
The models have been flight tested up to 525 kg takeoff weight and static tested +6 / -4 G force.
Water take off run is 7/10 seconds in less then 80 mt., with two persons on board. Landing run is less than 60 mt.
Land take off run is less then 60 mt. with two persons on board. Landing run is less than 90 mt.
