How to repair a toy 4x4 will become faster and more powerful, and, fine 50

In addition to increasing power, it is important to improve lubrication, lubricity is improved, natural resistance is small, and the speed is fast. Professional fully synthetic lubricating grease should be used, both Hotolube and Kruber's can be. Colorless and transparent, no odor, safe for the body, with food-grade certification.

You can check out the leopard leopard, which has a 130-gram tube package, which is very suitable for toy 4x4s.

Special attention should be paid to the lubrication of toys to the safety of the body, and it is not advisable to use engine oil or ordinary grease, which will emit harmful odors. Please ask for a food grade certificate at the time of purchase.

The speed of the four-wheel drive car mainly depends on the power system is how the motor is used No. 7 enameled wire winding motor is fast and power-saving Coarse power consumption Endurance is not enough Thin is slow motor magnet selection of strong magnets to achieve greater torque output All shafts are replaced with bearings The place where the axle and guide wheel reduce friction and enhance stability.

Motors, bearings and strong magnets are basically good to have.

What's a 4WD? Game?? Or is it realistic? Toys for motors, bearings, batteries.

What is a fine film? I didn't understand what you said, I didn't have that when I played before.

1. Motor, motor is the core of the car, just like the heart, is the most direct factor of speed, there is a good motor, in order to make the car "soar". Most of the motors sold on the market are machine-wound, and the saturation of the enameled wire and the shaft is very poor, so it consumes power and does not run very fast, but now some of them are manual motors, such as atomic fission (two-wire single-winding), V1, V2. Although these motors are wound by hand, the speed is not very ideal because of the single winding method.

Speaking of which, it is better to learn to wind the motor by yourself is the king, and you can choose different winding methods according to your interests to obtain higher speed or torque.

2. Battery. The battery is the source of motor power, and the Auldey double diamond 1800 mAh nickel-metal hydride rechargeable battery sold on the market is the first choice, with very little internal resistance and amazing explosive power.

3. Gears. The gear determines the running performance of the car, the large gear has a greater torque than the car, and is good at curve climbing, and the small gear has a higher speed ratio. The selection of gear ratio should be determined according to the motor torque, and the motor torque with magnets is larger, so a smaller gear ratio (3:) should be selected

1:1), of course, depending on the winding of the rotor. For motors with low torque, large gear ratios should be selected to obtain higher torque.

4. Miscellaneous. Other factors include the weight of the body, which is kept as low as possible. For wheels, it is recommended to choose narrower wheels, which are more labor-saving and have good acceleration performance.

Tire friction, rubber tires have less friction and are not suitable for high-speed driving, because the high-speed rotating wheels are easy to slip when equipped with tires with low friction, resulting in a waste of energy. It is recommended to use sea tires, but sponge tires have too much resistance, a soft feeling, a large motor burden, more energy-consuming, and are not suitable for long-term driving. Guide wheel, the thinner the guide wheel, the faster the speed.

There are also subtle factors such as aerodynamics, lubrication, conductive sheets, etc., not much to say, I wish you a great time!

1: Change to a high-power motor.

2: The chassis should not be too light, and the adhesion is too poor if it is too light.

3: Check the wear parts, fill with lubricating oil, and minimize friction.

4: Increase the transmission ratio on the original basis, only in this way can you run faster!

Pick the most expensive motor, battery, tire to buy.

Don't get too heavy. Gears with 3 to 1.

The balance is done. Don't fly out quickly.

Changing to a more powerful motor is the most straightforward, and nothing else is useful.

1.Learn to wind the motor, 12 turns in a single line, make up for the weaknesses of the high-speed motor, use strong magnets, use high-speed gears, (the longer the runway, the more effective).

2.Narrow the wheels to reduce the burden on the motor (because the friction is independent of the Kar contact area between the objects)3Use a strong explosive Karma battery (War Dragon 2000mAh) 4I can use a bearing as much as possible in the place where I can use a bearing.

5.In order to achieve the best effect, the upper layer uses a Ka plastic guide wheel with less friction (Audi), and the lower layer uses a Ka metal guide wheel with greater friction (Audi).

The above is suitable for use on relatively large runways (it is not effective to use on relatively short Kar runways).

First of all, the basis is that the friction of the axle is minimized, the friction of the gear is minimized, and the car body should not be too heavy.

Then the four-wheel drive vehicle is the fastest, that is, when the battery output power is the highest. By the formula of physics... When the average resistance of the motor is closer to the internal resistance of the battery, the easier it is to exert the power of the battery, so it is important to match the battery and the motor well.

Due to the problem of facilities, you can only try them one by one and find the answer yourself.

Times are changing, and the gameplay of 4WD 20 years ago is basically the same as it is now, and there are too many fun alternatives now, such as mobile phones. Four-wheel drive vehicles were eliminated.

First of all, four-wheel drive cars have not yet declined, there have always been competitions in Japan, and good cars are sold very expensive.

In fact, the most important thing in China's popularity is the popularity of cartoons, and now there are no new cartoons, and children's entertainment methods are more technological and diversified, so you can't see playing four-wheel drives.

You can take a look at Yu-Gi-Oh cards, although there are big competitions every year, and anime has been coming out, but because this way of playing can't keep up with today's fast and convenient online casual games, there are fewer people playing them.

If the rotor remains the same, and the stator with a stronger magnetism, such as a rare earth strong magnet, the stronger the torque of the motor, the slower the speed (but not too much), and vice versa, the weaker the torque.

This needs to be carefully adjusted with the winding method of the rotor, and it is easy to have the opposite effect if it is not done well. For example, some players are too eager for high torque and replace magnets with particularly large magnets, which will lead to an increase in motor heat, resulting in a decrease in motor performance or even burning.

First of all, the speed of the four-wheel drive vehicle is calculated according to the knots, for example, 30 knots per second, so it is close to 15 meters per second, so the speed can reach 50 km per hour, and from the fighting, modification, installation and other four-wheel drive vehicles can be armed to the teeth My car will reach about 40 knots per second.

I have a good motor, do you want to wind the copper wire inside by hand, and the speed is fast.

Toy 4WD? If you want to go brushless, the speed can break 100 per hour, toy airplanes are generally not fast, *** generally do not fly at speed, model airplanes have pulse machines, that fast (the power used by flying missiles).

The speed of the 4WD is calculated by knots, it seems to be 1 second 56 knots!

1. Leopard 62000 rpm, computer design high wear-resistant alloy commutator, suitable for straight line sprint.

2. Jaguar 55000rad min shell has good heat dissipation performance, and the front and rear covers are made of oil-impregnated shaft sleeves, and the speed is very good.

Jaguar 55000rad min high wear-resistant alloy commutator, high speed suitable for all kinds of tracks, good comprehensive performance.

The Gold Speedmaster 32000rad min has a strong torque at medium and high speeds, and consumes moderate power to work continuously and durably.

Silver Speedmaster 28000rad min low speed, strong magnetic field, high torque, power saving, suitable for multi-curve driving.

Jinba 25000 rpm, air-cooled motor, alloy magnetic block brush, high speed but the motor is not easy to heat, can work continuously for a long time, suitable for endurance rally.

The rest don't know that the world speed of the four-wheel drive car was created by Chinese athletes
