Design and piloting of the model fully understood from the drawings and therefore requires no further explanation. The only thing I would like to highlight the need for a preliminary calculation of loads on the cords.
The fact that the developed rudders and flaps at the maximum deflection angles can give such hinge moments of control efforts will be missed. Then the only solution would be to increase the “scope” of the swing and the distance between the points of suspension cord on the handle. The method of calculating the moments repeatedly cited in our magazine.
R and S. 1. Basic geometric data cord aerobatic models under the engine working volume of 2.5 cm3.
R and S. 2. Fuselage:
1 — uneven bars engine mounts (beech), 2 — front area, sheathed plywood with a thickness of 1.5 mm on the left side of the fuselage, 3 — boss (Linden), 4 — back boss (Linden), 5 — filler (foam), 6 — slats kit of the fuselage (Linden slats section 1,5×20 mm) 7 — trim (Linden, thickness 1 mm).
R and S. 3. Removable console wing:
1 flange (glued on a mandrel of four pine slats with a cross-section of 1×3 mm), 2 — Polonnaruwa (Linden, thickness 1 mm), 3 — rib (lime, 1.5 mm thick), 4 — shelf side member (pine, cross-section of 4×10 mm on a cone to the end of the console to the cross section 4×3 mm), 5 — root rib (ply, thickness 1.5 mm), 6 — root sheathing (Linden, thickness 1 mm), 7 — pin xation of the bracket on the fuselage, 8, the root rib of the flap (build from Linden slats), 9 — thread suspension components guards, 10 — front edge of the flap (pine, cross section of 3×5 mm), 11 — the rear edge of the console (pine, cross 5×12 mm), 12 — contour cropped, right-wing, 13 — different insights of cables, eliminating the hook carabiners cord when flying.
