In the beginning there was a dream, to make a new glider which would capture passion for termic flying. After two year long hard development, it's honest for us to present you an Asperatus F5J.

It's the glider intended for the best experiences in air. We achieved that by using the best avaible technologies and highest grade materials. The construction is all hollow multilayer composite vacuumed in forms in combination of glass and carbon fibre composite according to version. Stiffness of the wing is very good thanks to linear carbon fibre reinforcements and balsa wood struts. Fuselage is full carbon fibre, from combination of 45° fabric and linear fibers in the whole lenght giving it an extreme anti twist stiffness. It can be painted or with raw carbon fibre look. Airfoil is very slim and changing in whole lenght of the wing, which allows plane to reach various amount of speeds. Winglets at the ends of wing help to lower drag, better stability and lower radius of rotation. Standard equipment supplied with plane is set of 5° carbon fiber wing connectors and installed cables, servos mounting points and covers and engine counter. On request plane can be equiped with Balast set, wich include changeable 133, 212, 262 and 338 g weights mounted in fuselage in three possible possition for center of gravity changes or with 7° wing connectors. 

There are three avaible versions of Asperatus, Relax, Competizione and Competizione Ultraleggera.

Relax version is intended for recreation flying, it can handle wind up to 6 m/s. Material of wing, horizontal and vertical stabilizers is double glass fibre composite.

Competizione is uncompromised racing machine. Higher weight of this version predetermines it for flying in stronger wind. Wings, rudder and elevator are made of glass composite but on request we can make them from biaxial carbon fiber.

Competizione Ultraleggera is almost same as Competizione but weight has been reduced with standard use of biaxial fibers on all parts. All surfaces are not painted except ornaments.
