ROCKET FROM THE SPORTING PAST

MISSILE WITH a SPORTS PASTa Spectacular high-speed radio-controlled model-polyopia missile boats based on the hull of the sports racing model, has been one of the trends of creation of ships with dynamic principles of maintenance, the moving in partial planing. For such ships ostroslovy distinctive lines and a constant deadrise of the aft part of the hull.

 

Although the RC version of this model more attractive, but young athletes may be able on the basis of high-speed “train” to make the unmanaged model — you need only equip it with a pair of power units with propellers and install additional keel plate, which will increase the accuracy of retention rate.
 
Body of this model is classic — with a set of plywood frames, the joint strips-stringers. The frame is assembled on a powder-coated epoxy adhesive. Recruitment needs to be extremely lightweight because lightweight model allows you to equip it with batteries larger mass and hence significant energy consumption.
If you have the opportunity to get the balsa, then this material would be perfect for the frame. However, it is quite fit and a foam type of PVC, laminated with two sides of glass fiber epoxy binder.

layout in the case of input equipment for remote control:
 
1 — motor; 2 — the block of four batteries with a capacity of 1.2 A-h; 3 — receiver; 4 — channel servo control rate; 5 — channel servo control frequency of rotation of the electric motor; 6 — two-step controller the motor speed

 
Prior to Assembly in the frames 4,5 and 6 are laid out rectangular cutouts for the power system, servos, speed controller, receiver and batteries, and then using a jigsaw on the markup cuts are made, allowing further easy to remove (just, break) notched the inner part. Prepared in this way frames are placed on a smooth rod Assembly cross section of 6×6 mm. Then using a soft copper or safety wire are fixed in their places the rail-stringers. After checking the assembled frame to the symmetry, the parallel arrangement of frames and their Assembly indicate instead rod in each junction is introduced svezhenakleennyh epoxy adhesive.
After polymerization of the adhesive and removal of the wire is glued in the front part of the keel. The nasal boss is cut from dense balsa or, at least, of lime. The zygomatic part of the bottom vyklevyvajutsja balsa or lime plates, which after curing of the binder processed in accordance with the theoretical drawing of the hull.
 
The bottom portion of the skin cut from 1 mm plywood. The pattern makes sense for them to make a dense drawing paper by the method of successive approximations gradually cutting the outline of the paper blanks and attaching it to the frame with pins.
 
Radio controlled model-polyopia missile boats
RC model-polyopia missile boats:
 
1 — the flagpole; 2 — rail; 3 — cleats; 4 — tilting plate; 5 anchor capstan; 6,20 — bow and stern artillery systems; 7,17 — whip antenna; 8 — side a distinctive fire; 9 — signal floodlight; 10 — brackets-ladder; 11,18 — radar antennas; 12 — white masthead light; 13 — mast 14 — a box for signal flags; 15—gyrocompass repeater; 16 — cateway fire; 19 — white hamborsky fire; 21 — rudder; 22 — rowing WINNT; 23 — stern tube; 24 — farm of a missile container; 25 — missile container; 26 — the Foundation of the electric motor; 27 — poluchaut; 28 — screw; 29 — motor; 30 — anchor; 31 — anchor stopper; 32 — deck hatch; 33 — ventilation fungus; 34 — combat tower

1 — the shell (plywood or thick cardboard); 2 — brackets-ladder (d2 wire)
 
Pins and clamps-clothespins are attached first to the frame and the plywood workpiece. This temporary attachment allows you to precisely adjust the workpiece as the frame, and to each other. Similar fit to the frame and the plywood workpiece of a covering of boards. The covering to the frame is glued with “epoxy”. In conclusion, on the bottom are fixed in the longitudinal planing steps from birch or beech slats of triangular cross-section, and the inner surface of body is covered with two-component (e.g. parquet) varnish.
 
It is time to extract from the frames of the hull cut off the inner part, freeing up space under the platform on which are fixed the power plant and remote control equipment.
 
Further, the case drilled with maximum precision fit holes in the deadwood and rudder stock tube. Set the Foundation for the motor, cut from the fake block. The motor is attached with aluminum clamp, fixed on the Foundation with the four screws. Installing in place of the power unit, check the ease of rotation of the shaft and stern tube, if everything is in order, deadwood glued into the case.
The basis of the power plant model boats is the electric motor power of about 60 watts running on the propeller with a diameter of 30 mm, In principle, can be mounted on the boat propulsion installation of the two less powerful engines — spark boat helps to better stay on course.
 
A current source are the four “AA” battery with a capacity of 1.2 A-h that allows the model to move at full speed for 12 minutes. The engine speed is regulated by a discrete two-stage switch in which the switching 10 W resistors 4.7 Ohm. However, if possible it is better to equip a power unit with electronic speed controller — these are quite often used by modelers.

After mounting the power unit in the housing is glued in plywood bottom of the Central compartment in which are mounted a rechargeable battery,
the lift and speed control of the motor, and a vertical plywood walls — foundations servos.
 
The deck is sheathed with balsa veneer with a thickness of 2 mm. While it remains a hole, repeating the form of the “combat logging”. The resulting contour of the opening is enclosed inside rails cross section 5×2 mm.
 
“Combat cockpit” is going on epoxy glue from the 1-mm of plywood or cardboard. Missile containers can be glued of thick drawing paper or, better yet, match them to suitable plastic tubes. Farm-base containers are collected on the glue from polystyrene rods-blanks. The mast is wooden, sensible things — polystyrene or plexiglass.
 
All add-ons are colored in gray (ball) color. The same color is painted and the upper part of the side, to the waterline. Below the waterline the hull has a red or green color. The bollards, capstan, chain stopper, and anchor — black .
