The performance of the nacelle does not require special explanation, in design they are similar to the fuselage.
The control system includes a rocking chair made of insulating plastic rod, made from the stem of chiy, and the simplest actuator of the elevators of the usual type.
Landing gear carved bamboo, paper helped accurately reproduce all the thickening on the uprights and their braces. Thin celluloid went to the imitation shutters hatches chassis. Wheel of finely porous rubber is sandwiched between the halves of the hub (MA-1T).
Completely finished, assembled and finished copy is checked for the correct position of center of gravity set such small details as the instrument air intakes, antennas, flaps rudders, and simulate navigation lights and machine gun. In most cases, the best material for them is solid bamboo, its use will insure the finest elements from damage when the model runs.

It remains to make a control knob with a variable resistance to adjust the “gas” and Konami in assembling the power supply. The model flies well on two strands of wire marks PEL Ø 0.25 mm with a length of 4-5 m. as the current source used ten Nickel-cadmium batteries the SAG is 1.5. giving average PA handle about 12 V.
I want to mention another variant of the model, Il-4, also developed in our group, copies of the dugout with a boxy fuselage and a full simulation of the hard skin of the aircraft. This Model melkosortnogo cut from the packing foam. Surround the nose and nacelles extruded from thin sheet celluloid, the chassis has a valid depreciation stands, repeating the design of the prototype, and wheel-quilted welded from raw rubber. This model looks just like the real Il-4, but a few flies worse than the first. May be affected by the shortcomings of used engine brought heavy and thin (he is one, by two screw rotation is transmitted by belt from the drive counter of the tape recorder “Comet” so that the motor shaft is unloaded from the influence of the radial force), heavy and finish — it is made with white glue, followed by color. Take-off weight of 200 g. copy
And we talked about this model why. As it turned out, to the “trains” should be taken quite seriously. I hope that they will eventually get in line with the sports models. But the new vehicles for missions in the premises requires a new approach to the design of any element. And we are sure that in the end, using another, it may be a classic, twin-engine scheme of the plant and different methods of exterior foam, you will be able to “teach” a copy of Il-4, very close to reproducing the prototype to fly as well polyopia. And our experience will be useful for adherents of electrosetstroy.
