Required tools and materials
For assembly and preparation Goldfish to 162 You need a set of tools to run the first time, and you don't have to rely on a random set of screwdrivers, because you need to be careful with miniature electronics and precision mechanics. A quality tool It is an investment in the longevity of your model.
First of all, you'll need soldering gear, and the brazing of the wires to the connectors and motors should be perfectly designed to prevent contact oxidation in humid conditions. lead-tank with roniflus or modern lead-free analogues with flux.
⚠️ Attention: When working with a soldering iron near the plastic elements of the case, be careful. Molten plastic can irrevocably damage the parts, and flux vapors should not get inside the sealed compartment until final assembly.
And you also need measuring instruments, you need a multimeter to check the integrity of the circuits and the voltage on the batteries, and you need a mechanical part to have a superfill, sandpaper of different grains, and maybe a nap to fit the seats.
- 🔌 A soldering iron: 25-40 W with a thin sting.
- 🔋 Multimeter: for the diagnosis of electrical circuits.
- 🔧 Screwdriver kit.: including cross and schlitz in different sizes.
- 🧪 Chemistry: degreaser, silicone lubricant, thread fixer.
☑️ Preparation for assembly
Step-by-step assembly instructions
Assembly process Goldfish 162 starts with the preparation of a sealed compartment, which is the most important step, because it depends on the survival of electronics, carefully clean the inner surface of chips and dust, install bulkheads, making sure that the seals are tightly attached.
Then there's the mounting of the engines and the shaft. The shaft should rotate freely, without beating. slip-bearing Or rolling in a lower unit will reduce friction significantly and increase engine efficiency.
Moving sequence:Installation of bulkheads into the GO pipe.
Installation of the engine and engine.
3. Folding the pipe.
Installation of servo drives on brackets.
5. Electronics switching.
Installing electronics requires care. Place the receiver and the regulator so that they do not heat each other. It is advisable to bring the receiver's Anna out through a special port or place in the upper part of the housing, not shielded with metal. Cable management inside the compartment will help to avoid confusion and damage to the wires.
The sealability of the hatch is a critical success factor, and before each launch, check the condition of the sealing ring and the absence of foreign objects on the landing plane.
Radio equipment setting and balancing
After the physical assembly, the adjustment stage begins. Goldfish 162 standard requires at least three channels: gas (screw), depth (horizontal steering wheels) and course (vertical steering wheel).
Pay special attention to the alignment of the model. The submarine should have a slight positive buoyancy in a neutral position. To check, immerse the model in a bath or a container of water. If it sinks immediately, add foam cargo to the nose or stern. If it pops up too quickly, increase the weight of the ballast.
Setting up horizontal rudders They need to be finely adjusted, they have to be able to go smoothly as the stick deflects down and to come up when it deflects up, and overreacts can lead to a peel and the model goes to a depth where it can't come up.
⚠️ Attention: Never turn on electronics outside the water unless the motor is rigidly attached or connected to a loaded shaft. Rotating the screw in the air can cause the motor to become unbalanced and the regulator to overheat.
Operational rules and maintenance
Operation of the model Goldfish to 162 You need to follow a number of safety rules: run the model only in clean water, free of debris and algae that can wind on the screw. After each run, be sure to remove the battery and wash the body with fresh water, especially if the launch was in a salt water body.
Regular maintenance will prolong the life of your submarine, and once a season it is recommended to dismantle the seal compartment, lubricate the moving parts and check the condition of the wires. Galvanic corrosion It can imperceptibly destroy contacts, so visual inspection is mandatory.
Store the model in disassembled form or with open hatches so that the inside does not accumulate moisture, batteries are better stored charged 50-60% in a cool place. submarine serve you for many years.
- 🧼 Washing: mandatory after each release to salt water.
- 🔋 Batteries.Keep it separate from the model in a fire safety bag.
- 👀 Visual controlCheck the screw and steering wheels for damage.
What to do if water gets into the airbag?
Remove the batteries immediately! rinse the electronics with distilled water (if it was in salt water) or alcohol to displace moisture. Dry the dryer thoroughly at low temperature for 24-48 hours before re-energizing.
Frequently Asked Questions (FAQ)
What is the maximum dive depth for a goldfish to 162?
The design of the model allows you to safely dive to a depth of 1.5 meters. Further immersion is possible only with additional sealing and strengthening the body, but this is not normally provided.
