9-th January Jiří Vychopeř â?? technician of LAA assisted by SHARK's first wing prototype assembly, together with member of LAA technical commision Marian Mečiar and Shark's stressmen Ludva Bedřich . 2,6 kg of first flap does not look bad.


First â??dryâ?? assembly of fuselage shell and interior-shape parts â?? to adjust and confirm its position and connection areas before gluing


Check of wing beam glued in bottom wing part. Areas prepared for glue application are limited by self-glue strips


Then side areas are protected opposite to â??cryingâ?? epoxy, and all glued areas are â??revivedâ?? by light layer of Epoxy glue


â?Śthen there are applied thick layer of toughened Epoxy in all connection areas â?Ś


Looking like from bakery â?? when bakers decorate Christmas sweetmeats â?Ś Very important is visible white line, prepared for red-plastic savers removing after wings are glued together â?? to remove overflowing Epoxy after wing mold closing.


Last application in opposite mold of top wing mold â?? gluing of aileron root-rib


Both parts of wing â?? still in negative molds â?? are closed and pushed together by screws around wing â?? jigs.

Next day left wing was removed from negative molds and first time connected with flaps : Hinges of flaps are creating not-divided aerodynamic profile after flap is retracted

Actually COMP-LET weighing of assembled wing takes very nice 16,65kg. Of course it is without final control system installation, electricity, flap laterals and finalization of fuel tank ...
