TREHREZHIMNY HYDROPLANE

TREHREZHIMNY HYDROPLANEHigh speed RC model with electric drive is very popular with modelers-but-wickow and veteran athletes. This to a large extent contribute concise external form guide-registerof prototype that simplifies the design, allows you to make models from a variety of materials and used in the manufacture of a variety of technological methods — depending on experience, availability of certain materials and finished components (engine, onboard equipment and batteries).

We offer one of the simplest options of the model panel design.
 
The Central building of this model consists of a rigid box with flat panels sidewalls. Each panel is made of plywood with a thickness of 1 mm, contoured pine rails 4×4 mm, and foam fill. Installation of panels is produced on a flat Board (the stocks), gluing with epoxy resin, condition until polymerization of the resin under pressure.
 
After gluing and finish panels are joined with pine slats cross-section of 4×4 mm. In the rear of the case is set to transform the Board from a 5 mm plywood in the front with the pine lug of triangular cross-section.
The housing has a removable cover, consisting of cover (1 mm plywood), longitudinal ribs (3 mm FA.Nera) and transverse walls (3 mm plywood). Fixation of the cover on the case with a simple spring latch.
 
The inside case is divided into four compartments — the motor, battery, control and steering. In the first strengthened bulkhead made of plywood 4 mm thick is attached the engine Speed 600 Graupner company, working together with a two-bladed propeller with a diameter of 35 mm and 47 mm. a step Managing running speed of the motor is carried out using the speed controller of the remote control. In the second compartment is a battery of seven Nickel-cadmium elements with a total capacity of 1.2 A”h voltage of 8.4 V. In the third — receiver, dual channel proportional equipment. Well, in the fourth — steering machine with remote control system.

1 edging side panel (pine rack 4×4); 2,8 — filling (packing melkosortnyj foam); 3,7 — sheathing panels (plywood s1); 4 — bushing (D16T); 5 — deck plating (plywood s1); 6 — cross-member upper (pine rack 4×4); 9 — casing the outer cheekbones (plywood s1); 10 — stringer (pine rack 4×4); 11 — cross-member lower (Sosnovaya 12×4); 12 — hull bottom (plywood s1); 13 — boss bow (white); 14 — Board transom (plywood s4); 15 — tube of water cooling system of the motor.
 
Right float

 
Right float:
 
1 — the axis of the fin (M3 screw with two nuts and washer-Pro-masonry); 2 — fin (D16T, s2); 3 — bracket (D16T, z); 4 — M3 screw; 5 — spring; 6 — a bolt with a nut.
 
Locking the float on the beam bridge
 
Locking the float on the beam bridge:
 
1 — M4 screw 2 — rubber Bush; 3 — beam (pipe Ø8х I); 4 — panel float side; 5 — washer; 6 — bushing (ДІ6Т); 7 — threaded bushing (steel).

 
If necessary, you can do liquid cooling of the motor, which significantly increases output power to them. For this purpose the engine is equipped with a tin shirt with two pipes; one of them is fed a plastic tube connected to the intake on the float and on the other the same discharge pipe the heated water overboard.
 
The floats of a hydroplane is also a panel design. It consists of a pair of side panels, cross members, transom Board and plating of decks, bottoms and cheekbones. Materials — 1-mm and 3-mm plywood and pine slats 4×4 mm melkosortnyj and packing foam. The Assembly epoxy resin.
 
Each panel floats going from 1 mm plywood edging strips of a cross section of 4×4 mm and foam fill. Next, the side panels are connected by cross strips, nasal bosses and transom boards; floats are glued into the mounting sleeve. After curing of the adhesive on the frames secured with plywood sheathing.
 
The finished hull and the floats using epoxy resin pasted a layer of thin fiberglass. Next — Vykurovanie and paint topcoats.
 
Dock floats with the body is carried out using a double beam bridge, consisting of a pair of duralumin tubes with a diameter 8×1 mm. note that the rear beam is bending in the area of the coupling connecting the propeller shaft with the motor shaft. With side panels enclosure rods are connected through a thin-walled dural sleeves glued into the panel. For fixing the beams to the floats they built thin-walled sleeve made of aluminum; the attachment of the floats by means of clamps, each of which consists of a rubber bushing, M4 screw, washers and threaded bushes glued into the beam. When tightening the clamp screw rubber sleeve increases in diameter and firmly jammed the beam relative to the sleeve of the float. This mounting scheme allows to slightly change the distance between the floats for optimum performance of the model.
