NON-MOTORIZED ACROBAT

NON-ACROBATThe increase in the number of athletes, creating a model with a remote control, is not to the detriment of the adherents of the cord. The fact that even “radiosporten” make their first steps in aircraft modeling, holding the control stick Assembly. However, before you build a model internal combustion engine, it makes sense to make the apparatus easier — non-motorized. This will enable the beginner to master the piloting skills necessary for the management of more complex kordovye models. Moreover, this no-motorboat can make even the elements of aerobatics like inverted flight and loop.

The offered machine is highly easy to manufacture and does not require scarce materials. Pine slats, plywood, foam, steel wire, that’s all you need for work.
 
The fuselage is carved from pine slats with a thickness of 10 mm and a width of 22 mm. At the front there is installed a spring-loaded landing ski, curved steel wire with a diameter of 2 mm. In the Central part is cut under the wing and is glued end-to-end beech pin diameter 5 mm for wing mounting rubber bands. To model was similar to a real plane in the upper part of the fuselage is attached a lantern carved from a clear plastic bottle, you only need to find a suitable place.
 
The wing is made of pine boards with a thickness of 8 and a width of 170 mm. the Board should be straight grained and not have knots. Wing span is 1000 mm PLANO-convex wing profile is the same across the span, so it is recommended to scan the form using a plywood template.
After processing and finishing the wing cut out in this window of relief, which after painting melmarium filled with packing foam, and then are taping-with duct tape. Although you can do without the foam, obtenus lightweight wing Mylar film.
 
On the left wing fixed the curly brace wire with a diameter of 1 mm for the wiring cord management. On the same console is set rocking, cut out of sheet aluminum with a thickness of 2 mm. Axis of rocking is the screw or M3 screw with nut.
 
Non-training control line model airplane
 
Non-training cord model:
 
1 —load balancing (nail Ø4); 2 — fuselage (pine, rail 22×10); 3 — ski landing (steel wire Ø2); 4 — light (part of the plastic bottle); 5 — ring rubber mounting wing; 6 — wing; 7 — pin (Ø5 beech); 8 — control rod (aluminum needle); 9 -keel (plywood s); 10 — Elevator (pine, plate z); 11 — stabilizer (pine, plate z); 12 — rocking chair of management (duralumin s2); 13 — hog upravlennya Elevator (steel wire 01,5); 14 — the hinge of the Elevator (nylon yarn); 15 —brace notched for the wiring cord; 16 cords management model.
 
Control handle model

 
Control knob model:
 
1 — lead (steel cable Ø2); 2 — housing rockn (funera s 12); 3 — clip (2pcs).

 
The stabilizer and Elevator are cut from pine plates 3 mm thick. Hinge the rudder to the stabilizer — nylon thread. Pre-and rudder, and stabilizer holes are drilled 1 mm.
 
Pylon rudder bends from a steel wire in diameter 1 — 1,5 mm. the Finished item inserted into a pair of holes on the Elevator and tightly crimped with pliers or in a vise, as shown in the figure.
 
The keel is made of plywood with thickness 3 — 4 mm For fastening it to the fuselage in the last propisyvaetsya the groove on the thickness of the keel.
 
The Assembly of the casein, or polyvinyl acetate glue. After Assembly and final surface treatment model is painted with nitrocellulose.
 
In the front part of the fuselage is drilled a longitudinal hole with a diameter of 4 — 5 mm in which is inserted a nail, performing the role of the centering of the load.
It makes sense to start with a long nail and gradually shorten it in accordance with the results of the test flights, achieving optimum stability of the model in flight and its handling.
 
The model is run in two 5 meter cords. The control knob is cut from 12 mm plywood and equipped with a simple device to adjust the “neutral” cable, passed through a maze of four holes. It is easy to be fixed, which allows for horizontal flight models and neutral Elevator to achieve the vertical position of the control knob.
 
To run the model recommended to the assistant. That model did not lose speed, the pilot needs to actively promote its outstretched hand, or, as the athletes, to carry with him. To control the model smoothly, double movements (action — return to neutral). Having mastered the control of the model in horizontal flight, you can go to the elements of aerobatics. For example, the running loop. For a start, the pilot model accelerates to its maximum speed when the neutral position of the Elevator, and then smoothly sends the control knob “on” and at the same time the whole hand “pulls” the model of the trajectory loop.
 
The fit of the model usually doesn’t cause any difficulties. With decreasing speed of the machine is reduced, and only need not to miss the moment and smoothly to get the control knob to “on” at a time when the wing ceases to hold model in the air.
