Description

Technical description

The wing is made of glass fabric and rohacell using sandwich technique. The main beam and all reinforcements are made of carbon fibres. The rudder and elevator are made of glass fabric and filled with rohacell core reinforced with carbon tubes. The fuselage / body consists of 2 parts – front nacelle and carbon tube. The front nacelle is made of glass fabric using compressed air which results in lower weight and maximum strength of all components. The wing contains 2 servo shafts for winglet and 2 servo shafts for lift flaps serving for rudder and elevator control.
