Accurate location of internal structures is ensured using templates (above left) for the wings, stabs, fuselage, fin, and rudder. Prior to joining mold halves, internal structure components (above center, above right and below left) are added. The thin white “stripe” between the aft wing spars is where the airex
foam has been relieved to allow the surface skin to act as a hinge. The landing gear (below center) is also a composite assembly of carbon fiber cloth with cores of wood in the mounting area and foam in the leg area. Even the carbon fiber wing tube (below right) is molded by RC-Composit.
Control surfaces are molded with the “parent” surface and cut free after the part is removed from the mold (above left and center). A section of the bottom skin of the stab/elevator is removed and then a curved hinge seal is affixed to the elevator leading edge which keeps the hinge gap sealed over the range of deflection. The Europa rudder (above right) is cut from the fuselage and a
leading edge piece of half round fiberglass is added. Hinges are located within the half round fiberglass, creating a “pocket” hinge that maintains clean aerodynamics and appearance. Just prior to being shipped to the US (below left and right), the Europa Pro LT(Yuri) assembled fresh out of the molds. The construction time usually ranges around four to seven weeks.
