RE: BEGINNER'S BUILD - Tower Trainer .40
Photo 1) Built fin and rudder last night. The frame of the fin and dorsal fin built with 1/4”x1/2”x36” balsa stick. The inner framework built with 1/4”x1/4”x36” balsa stick. Gusset in top corner from 1/4”x1/2” balsa. The left-over 1/4”x1 3/8”x30” balsa from the elevator makes up the rudder, which I have here roughly shaped and the top corner rounded. It is important not to glue the dorsal fin to the fin until AFTER the fin is glued to the fuselage
Photo 2) Tail-feathers taped and sanded smooth, edges rounded to shape
Photos 3, 4 & 5) L.E and top of fin, top and T.E of rudder, and top of dorsal fin all rounded to shape. The front and bottom of the fin are not rounded, leave them square for gluing to fuselage later. The bottom and back of dorsal fin are also left square
Photos 6, 7 & 8) L.E and sides of stabilizer, T.E and sides of elevator all rounded to shape. T.E of stabilizer is left square
L.E of elevator, as is the L.E of rudder are left square FOR NOW until hinges are installed, after which you want to bevel those edges to the V-shape
