TIMER “JUNIOR”

Tail boom wikiepedia of fiberglass epoxy resin. Will need a bar of lime, which grinds the front, Ø 36 mm, and the rear — Ø 10 mm. the surface of the wood is impregnated with epoxy resin and sanded before any work sealed with mastic for flooring. Fiberglass, annealed in a muffle furnace, cut, impregnated with epoxy and circumferential to the mandrel. If you use tissue thickness of 0.12 mm beam should be formed by two layers, with a thickness of 0.1 mm or three. The finished tapered tube is removed from the mandrel, for checking the quality of veclachi and adjust to the front of the fuselage. Gluing the two parts — epoxy resin, the butt surfaces are degreased prior to Assembly with acetone.

 

The tail part of the fuselage:

1 — the elements of border (Linden), 2 — Kiel (foam 5 mm), 3 — pull timer (line Ø 0.4 mm), 4 — “antennae” for clamping the wick (OVS wire Ø 0.4 mm), 5 — rudder (Linden), 6 — rocking of the rudder (celluloid 1 mm), 7 — tail boss (Linden), 8 — bezel (lime), 9 — emphasis of the stabilizer (foam), 10 — hook (OVS wire Ø 0,8 mm), 11 — bracket (celluloid 1 mm), 12 — unit control deflection, 13 — area of stabilizer (plywood 1.5 mm), 14 — tail boom (GRP).

 

SPAW fuel tank of tinned steel (Ø 25 mm, length 30 mm), it is placed in front of the lime tube. Then prepare the front frame of chetyrehkilometrovoy plywood (it must be a tube of the fuselage). Reinforce it by gluing a disc from polutorametrovoy plywood Ø 37 mm, then drilled three holes and mounted with glue screws with washers and nuts for mounting the motor and landing skids. The entire Assembly and the tank stuck on the front end of the fuselage.

The pylon is performed from selected quality plywood with thickness of 3 mm. After you cut it vyskazyvat and drilled two holes for the pins. The latter must be hard, must use wire brand OVS or piano. The installation of the pins is as follows. First, the middle of each is cleaned and degreased, wrapped in one layer of fiberglass, the seat is impregnated with epoxy resin, and the pins are inserted into the holes of the pylon. Immediately put the fuselage ribs and the whole package is clamped to the resin curing in the clamps. It should be noted that the ribs are prepared in advance, collecting each of the lime plates, mm plywood and accurately processed on the contour and the plane of contact with the pylon. After trimming the finished pylon to the fuselage it was glued tightly. The “feet” of the pole must pass through lime tube through.

 

A keel from the plate of foam with a thickness of 5 mm, on the perimeter of a banded fake reek. If you plan to cover the keel macalintal paper on Amalia, after profiling the entire part “varnish” slightly diluted PVA that will protect the foam from dissolving. The finished keel hung rudder and nodes mounted on the tail boom with epoxy resin.

 

Engine mount due to the fixation at three points ensures that unlike other options, a simple adjustment of the position of the axis of the propeller. The detail is milled from aluminum billet to fit the motor. In its rear wall are laid out and drilled three holes Ø 3.2 mm, and the center — Ø 11 mm for the branch pipe of the carburettor.

 

The finished fuselage after careful checking and correction of defects treated with sandpaper, fitted by a long-staple (michaletos) paper on Amalia and re-polished. Finishing — parquet varnish that protects wood from absorbing fuel and the associated increase of mass.

 

The wing consists of two consoles. Before starting preparation, it is necessary to mount the frame of two straight boards and to prepare sheet dural profile templates. Stapel, in addition to the Assembly frame is useful in painting trim and storage planes.

 

Console wing:

1 — power rib (1 mm plywood), 2 — the skin of the forehead (Polovtsian), 3 — rear spar, 4 — front edge pine (3X4 mm), 5 — spouts (Linden 1 mm), 6 — wing (micuenta paper), 7 — rib “eye” (Linden 0.8 mm), 8 — tip “lug” (Linden 0.8 mm), 9 — scarves (Linden 2 mm), 10 — ending (foam PVC), 11 — back edge (pine upon a time 3×13 mm, planing to wedge up to 1 mm) ,12 — mortise connection edges (celluloid 1 mm), 13 — rib (Linden 1 mm), 14 — rear spar.

 

The wing profiles (scale 1:1):

1 scarf (lime 2 mm), 2 — spar wall (plywood 1 mm between the first four ribs, then Whatman), 3 — shelf side member (pine 3X4 mm), 4 — shelf rear spar (white 2,5X2,5 mm), 5 — root rib (lip 3 mm plywood 1 mm), 6 — piping holes for the pins (celluloid 1 mm) 7 — wall (Whatman, between the first four ribs), 8 insert (Linden 2 mm).

 

Frame Assembly features does not, and ends with the installation of the root rib of parklea basswood and plywood. Toe covered with paper or polovitkina “wet” method, and all plane — dyed macalintal paper on Amalia. The paint is applied in three layers. During the drying in the stocks under the edges of the wedge enclose the slats to the desired twist in consoles. And they are: right console +1° left centroplane part -0,5°, the left “ear” of -1°.

 

Stabilizer the same as a wing, is going on the slipway-Board. The Central rib of slightly thicker fake veneer (1 mm) between them are pasted plates of PVC foam. Cording to her forehead — glassine imposed “wet” method. The cording of long-fibre paper varnished with Amalita only twice. Drying and storage are also on the stocks, which guarantee the preservation of a given shape during the period of operation of the model.

 

Stabilizer:

1 skin of the stabilizer (micuenta paper), 2 — the skin of the forehead (parchment), 3 — hook rubber ring (wire Ø 1.2 mm), 4 — skin-strengthening (foam PVC 2 mm), 5 — nozzle (Linden 0.8 mm), 6 — rib (Lipa 0.8 mm), 7 — shelf side member (pine 2X3 mm, without wall), 8 — the front edge (white 2,5X2,5 mm), 9 — ending (foam PVC), 10 — trailing edge (pine 2X8 mm, planing wedge), the 11 “mustache” determinator (OVS wire Ø 0,8 mm), 12 — hour (pine 3X3 mm).
