GIANT FROM ITALY

GIANT OF ITALYRC model airplane, provided in this publication, it is highly unusual for the national school of design. First of all it is established in accordance with more and more of the fashion for Maxi models (it is appropriate to recall that the rules of competitions of the International Federation of air sports is not the first year there is a subclass supermystery models). In addition, its overall design matches popular today modelers orientation on the old стиль1 when models are more like genuine planes 30 years, rather than a pure sports “shells”.

“Eagle” is the name of this radiosure — has a very simple, easily reproducible design. There is no dispute in its power scheme, one will find a number of sites that you can modify according to personal ideas or proven methods of construction. However, the model is good and in the present embodiment.
 
The model is mounted glow motor a working volume of 6.5 cm3 and apparatus radio control with the actuator of the rudder, elevation and regulation of “gas” engine. Despite a pair of solo scheme, the “eagle” with a relatively small load on the supporting surface are well piloted and moderate winds. And the flight of such a device is not an example more advantageous than the traditional aerobatic model. In addition, the form radiosatellite allows you to easily determine its position in the air at a considerable distance from the pilot.
In connection with the problem of transporting such a bulky unit, it is recommended to pay attention to rational decision nodes connecting wing panels and tail Assembly. For transportation is not so difficult to remove the main landing gear, then the whole model easily folds into a small convenient “bundle”.

I — side of the fuel tank (plastic tank volume of approximately 500 cm3), II the location of the receiver, III — the location of the battery, IV — placement of the servos. Bottom right shows the nose of the fuselage. Hatching the designated location, to be pasted on aluminum foil with a thickness of 0.5 mm for protection against damage of paint layers fiberglass engine hood.
 
Steerable tailwheel

 
Steerable tail wheel:
 
1 – wheel Ø30, 2 front (steel wire Ø2: damping and spring element shall have four turns), 3 – the bearing rotation stand (brass pipe, after degreasing gluing in the tail boss of the fuselage), 4 – carrier (steel wire Ø1,5: soldering PA choice seam with a coil of thin copper wire). 5 – the clip of the leash (the bending of duralumin sheet, s0,5), 6 – rudder.
 
The strut of the wing (four pieces)

 
Brace wings (four pieces):
 
1 — termination fuselage (steel wire Ø2), 2 — body brace (pine rack 10×5; profiling to teardrop-shaped cross-section), 3 — termination of the wing (steel wire Ø2; the outside end of the cut thread M2), 4 lock nut M2, 5 — tip steel (finished product to pull the drive wheels).
 
The details of the main landing gear
 
Details main landing gear:
 
1 — support front end-to-end (high-quality steel wire Ø4), 2 — bearing rear (steel wire Ø3), 3 — the clamp on the pillar (steel sheet, s1,5, 4 pieces).
 
 
Wing

 
Wing:
 
1 — ending (balsa veneer, s5), 2 — solitaire (balsa), 3 — the front edge (balsa rail 10x 10), 4 — shelf front edge (balsa rack 10×4), 5 — rib (balsa veneer, s3), 6 — Polonnaruwa (balsa veneer, s3), 7 – a main spar (shelves — pine slats 10×5), 8 — lug mounting brace (beech; on the outside of the frame of the wing by means of a screw to fasten the lug of steel sheet, s1… 1,5), 9 — spar rear (both shelves — pine slats 5×5), 10 — casing of the root partition bilateral (balsa veneer, s2), 11 —trim the root rib (plywood, s1,5), 12 — edge (balsa rail 20×8), 13 — the wall of the end section of the main spar (balsa veneer. s3), 14 — Klondike solitaire spar (balsa), 15 — a wall that is installed to the fixing struts (balsa veneer, s3).
 
Detachable tail

 
Removable tail:
 
1 — keel (balsa veneer, s6), 2 — joints, suspension steering, 3 — fairing reinforcement (balsa rail of triangular cross-section 6×6), 4 — stabilizer trim (plywood, s1), 5 —Central part of the frame (balsa veneer, s6), 6 — edge of the stabilizer (balsa slats 15×6), 7, 8 — the elements of the frame (balsa slats 6×3), 9 — solitaire (balsa), 10 — ending (balsa rail 15×6), 11 — edge of the rudder (balsa slats 15×6), 12 — element root rudder (balsa), 13 — bracket connection of the rudder (steel wire 03). Fastening the tail on the frame of the fuselage by means of four nylon screws M5.

 
The joints of koncowek with the body brace tightly wrap thin nylon thread and impregnate the binding with epoxy. The inner ends of the wire should be bent at a right angle, sharpened and driven into the rail.

In conclusion — interesting information: according to the proposed drawings were collected by reduced modification of the “eagle” under domestic compression motor KMD-2,5. Power circuit of this model is simplified, and the whole structure was reproduced of the available materials — Linden, pine and 3mm plywood with little use of plywood-“graph paper”. Mini”eagle” was also a good flight characteristics, which enabled him faithfully to serve for two years. The wing span was 1600 mm, so the console was made permanent, although the pair of struts are still preserved. In addition, modified the nose of the fuselage, which eliminated the need to manufacture fiberglass hood.
