LAK17B FES is latest development from LAK17A. Compared to A version, B has
modified wing geometry and new wing profiles, which allows same
max wing loadings like best sailplanes in 18m class. Fuselage and
tail section is similar as well known A version.
New wings for B versionFrom the start they were optimised for 18m wigspan with possibility of 15m tips. New aerodinamic knowledge lead to new wing airfoils, which are based on higher maximum lift coeficient. This princip proved to be very succesfull on Diana 2 and ASG29. With new airfoil there are better climb performance, with higher wing loading, especially in turbulent thermals. Maximum take off weight with 18m wing span is 600kg, which mean wing loading 58kg/m2!
