Wing attachment on Hippi-äinen !

Wing will be attached by three bolts. To make this secure the wood composite is still being developed ( glues, temperature, pressure ) to make it perfect. Spar and main fuselage formers have a bird wing like main strong points...at the front of the wing foils ( leading edge ) and near spar caps. 51st test was made with the wood composite over the weekend. Slightly denser ( ca 1400 kg/m3 ) than the Pregwood of the thirdies ( 1350 kg/m3 ).
