When playing RC climbing cars, especially compact models like the SCX24, the most troublesome problem often lies in the original steering gear. Have you ever encountered a situation where the car seems weak when turning, the return angle is inaccurate, or the steering gear suddenly stops working when climbing on complicated terrain such as rocks? Don't worry, today we will discuss in depth how to use the "key" of reefs 99 microservoto effectively and completely open the performance door of SCX24.
In the process of playing RC climbing cars, especially when faced with such a delicate car as the SCX24, the problems caused by the original steering gear are really troubling. When steering the car, you will obviously feel a lack of power, and it is difficult to accurately control the correct direction. Even when challenging difficult movements such as climbing rocks, the steering gear will stop running. Don’t panic when encountering these situations. Today we will discuss how to use the unique “key” of reefs 99 microservoto comprehensively and deeply open the door to SCX24 performance improvement.
The original servo equipped with the factory has the problems of low power and low accuracy. This is undoubtedly the most critical shortcoming that limits the climbing performance of SCX24. The reason for replacing the steering gear is not because the original steering gear cannot be used normally, but because we hope to make the car more stable and precise during climbing, thus giving the driver more confidence. The reefs 99 steering gear is an upgraded component specially designed for micro climbing vehicles. It has the remarkable characteristics of strong strength and quick response. When it is installed on the car, the car seems to have been replaced with a powerful arm, and the grip and passability can be directly improved to a new level.
Many novice friends will ask, can changing the servo make such a big difference? The answer is yes. The steering gear is the heart of the steering system. Only when the heart is strong can the blood be strong. If you imagine, on a rock wall that requires fine control, the original servo may slip due to insufficient power, but the reefs 99 can firmly fix the wheel at the angle you want. This is the difference.
The benefit is actually very direct, that is, the double improvement of strength and accuracy. The torque of reefs 99 is several times greater than that of the original factory, which means that even with big tires or the car body is very low, it can easily drive the steering. On complex terrain, you will no longer hear the embarrassing sound of the servo buzzing but unable to turn the wheel.
In addition, its accuracy is also critical. Metal gears and better circuit design allow the servo to maintain its neutral position particularly well. When you release the remote control, the wheels will automatically return to the straight line and run in a straight line. This is a must-have configuration for actions such as walking on narrow bridges or crossing one-sided bridges when climbing, which require precise alignment.
When choosing a servo, don’t just look at the brand, the parameters must match. First of all, you need to confirm the size. The space of SCX24 is very small, and a micro servo like reefs 99 can just fit in. Don’t buy one that is too big to fit. Secondly, look at the torque. Generally speaking, more than 5 kilograms is enough. Too much torque may damage the original steering cup.
Another point that is easily overlooked is the plug type of the servo. The original SCX24 is usually a JST 1.5 or similar mini plug. When buying reefs 99, you need to confirm whether it matches or whether an adapter cable is needed. Friends with strong hands-on skills can prepare a soldering iron in advance. Sometimes it is safer to solder by yourself.
Replacing the servo is actually not difficult, but there are a few pitfalls to avoid. The first step must be to disconnect the battery, safety first. When disassembling the original servo, remember to put away the fixing screws. The SCX24 screws are very small and difficult to assemble if lost. When installing the reefs 99, check whether the servo arm is aligned.
The centering step is very critical: first power up the car, let the servo automatically return to the neutral position, and then install the servo arm to ensure that the wheels are completely aligned. If you dress crookedly, you can't even adjust the remote control to fix it. In addition, the cables of Reefs 99 are thicker than those of the original factory. Leave a good space when routing the cables so as not to be pressed by the frame or rubbed by the drive shaft.
After installation, don't rush to the ground. You need to do simple debugging first. Turn on the remote control and the car, and check whether the steering direction is correct. If you push the joystick to the left and it goes to the right, turn on the reverse function of the servo on the remote control. Then check whether the left and right steering angles are consistent. If they are inconsistent, you can correct them through the EPA (End Point Adjustment) function of the remote control.
When testing the car on the ground, find an angled obstacle to test the steering response of low-speed crawling. You will obviously feel that the response of reefs 99 is more responsive, with almost no delay. If you feel that the steering speed is too fast and difficult to control, you can also reduce the servo speed appropriately on the remote control to make the steering action softer and more simulated.
Good things must be cherished. Although Reefs 99 is a metal gear, it is not indestructible. After you come back from playing with the car, use air blower to clean the dust around the servo, especially where the servo arm and the gear engage. Don't let small grains of sand get stuck in and accelerate wear and tear. Try not to steer in place for a long time, otherwise the servo will overheat.
Occasionally check whether the fixing screws are loose. SCX24 vibrates greatly and the screws are easy to loosen. If you feel that the servo becomes louder or makes abnormal noises, you can disassemble the servo arm and apply a little special grease on the gear. Do not use ordinary engine oil. If it is too thin, it will flow everywhere.
