Veron Verosonic. High performance sailplane. Building instructions.
First, study the plan and identify all the parts on the printed sheets of balsa. Familiarise yourself with these and all other instructions. This design, if carefully built, is quite capable of consistent contest durations of three to four minutes in still air from a standard FAI line length of 328 feet.
The only tools needed are small pliers, a few pinns, either steel backed razor blade or balsa knife, and fine sandpaper. The fuslage sides, wing and stabilizer panels and the fin are all built directly over the plan.
Wings: Lay the plan on the building board and cover with waxed tissue or greaseproof paper to protect from the cement. Select two even grade lengths of 3/8 x 1/8 for spars. Lay over plan and mark in pencil the positions of all ribs. Taper spans on top edge to 1/4 x 1/8 at R11.
