I last year made a fuselage 120 cm for the wing Horue xlw and I flew in winds of 8 knots. The fuselage is made of aluminum profile 20 to 40 mm and a wall thickness of 3 mm. This year I bought a wing Horue XXLW. Horue XXLW wing is very powerful and at the first gurney fuselage bent. And I made a drawing and gave it to the master CNC milling machine. My fuselage consists of two parts and you can make a fuselage of any length. We have tried to ride on the fuselage with a length of 1400 mm. Haven't tried as I will try to tell you.
