Title: Reviving the RC Car: Repairing and Upgrading for Enhanced Performance
1. Assessing the Damage
Upon evaluating the condition of the RC car, we have identified several parts that require repair or replacement. The chassis is bent, and after acquiring a 70 75 chassis from RC models, we plan on replacing it. Additionally, we aim to enhance the steering with an agf Servo and boost the power with a Taylor 35cc racing engine. However, we are cautious about potential hidden damage that may be uncovered during the process.
2. Dismantling the Car
To facilitate the repair work, we will start by removing the wheels and body of the car. This will provide easier access to the components in need of attention. Although the chassis we have obtained is designed for a version one car while ours is a version two, we hope to make it work with some adjustments. Despite differences in hole positions, we align the front and rear bulkheads, engine mounts, and ensure compatibility with the radio tray.
3. Tackling the Challenges
Unfortunately, we have not come across any version two 70 75 chassis options in the market. Therefore, we must focus on straightening the existing chassis as the temporary solution. While addressing the rear end damage, we encounter broken bulkheads, hinge pins, and sway bars. We carefully replace these components to restore the car’s structural stability.
4. Restoring the Radio Tray
The radio tray presents another area of concern. The latch is broken, affecting the throttle functionality. We will need to address this issue promptly to ensure smooth operation during the car’s performance. By acquiring the necessary replacement parts and meticulously installing them, we aim to bring the radio tray back to its optimal condition.
5. Upgrading for Improved Performance
Aside from repair work, we seize the opportunity to enhance the RC car’s performance. The agf Servo provides superior steering capabilities, ensuring precise control. Additionally, the Taylor 35cc racing engine promises a significant power boost, enabling the car to reach new speeds. These upgrades are poised to elevate the overall performance and thrill of using the RC car.
In , revitalizing an RC car requires careful assessment, strategic repairs, and thoughtful upgrades. Despite encountering challenges with sourcing compatible parts, we remain determined to revive and enhance its performance. Through meticulous repair work and the installation of superior components, we aim to bring this RC car back to its former glory.
Replacing the Dead Servos
Servo failure can be a frustrating issue for RC enthusiasts. In this article, we will discuss the process of replacing dead servos and the challenges that might arise during the replacement.
Choosing the Right Servo
When it comes to selecting a new servo, compatibility is the key. The steering servo and mount need to be replaced with suitable alternatives. In this case, a foreign agf 78-kilo servo is chosen for the steering, while a bang good special race star servo is selected for the throttle.
One of the challenges faced during the replacement process is compatibility. Most normal servos have an M3 screw, allowing for easy use of the existing arm that comes with the servo. However, in certain cases, such as with the agf servo, a M3.5 screw holder is needed. This requires drilling out a three and a half millimeter hole to accommodate the screw.
The Trouble with Odd-Sized Screws
Another frustrating aspect of replacing servos is dealing with odd-sized screws. In this case, a 3.5 millimeter screw is required for the agf servo. Unfortunately, these screws are not readily available and can be difficult to find. Losing such a screw can cause significant inconvenience and may require searching in specialised stores or online.
Dealing with Additional Issues
Apart from servo replacement, other unexpected issues may arise during the process. It is not uncommon to come across broken shock pistons or rims. However, having spare parts or utilizing parts from older models can save the day. This enables swapping of broken components with functional ones, ensuring the smooth operation of the RC vehicle.
Adapting the Taylor RC Race Engine
In addition to servo replacement, fitting a Taylor RC race engine may pose another challenge. The engine might be designed to fit a specific model, like the lossy 5T. Adapting it to fit the current RC vehicle requires careful consideration and possible modifications.
In , dealing with dead servos and replacing them can be a frustrating yet necessary task for RC enthusiasts. Finding compatible alternatives, addressing compatibility issues, and overcoming unexpected problems are all part of this process. With patience and resourcefulness, however, the RC vehicle can be restored to its full functionality.
The Problem with Engine Mounts on the dbxl
When it comes to engine mounts on the dbxl, things are a little different. Unlike the old engine mounts, this model doesn’t use them. Instead, it has a small plastic adapter that bolts onto the side and the engine attaches to it. However, if we switch over to the Taylor engine, we encounter some issues. Let’s take a closer look.
The Taylor Engine and Compatibility Issues
Unfortunately, the Taylor engine doesn’t fit onto the dbxl using the same method. Even if you try to turn it around, the spacing is all wrong. But don’t worry, there might be a solution. I happen to have some spare 70 75 aluminum that I’ve taken from an m2c chassis. Perhaps if I bolt that onto the engine with some drilled holes, we might find a solution. Let’s give it a try.
Fitting the Clutch and Testing the Results
Before we proceed any further, let’s make sure we fit the clutch onto the new engine. Once that’s done, we can proceed to bolt it onto the chassis and see how it all lines up. Ready to put it to the test?
The Disappointing Outcome
Unfortunately, it seems that our efforts might not pay off. The bracket we put on is only halfway on the hole, making it impossible to screw in. The option of drilling through the chassis to line up with the original mounts is not a viable one either. It’s clear that the alignment will never be perfect. However, I have another idea.
One Big Hole Solution
Considering the original engine mount was made of plastic anyway, let’s try a different approach. I suggest drilling one big hole in the middle, tapping it, and securing it with a single screw. While it may not be ideal, it could be our best option at this point. Let’s give it a shot.
After implementing the one screw solution, we can only hope that it will be enough to hold the engine in place. While the original engine mount was plastic, it’s important to manage our expectations. Sometimes, modifications require thinking outside the box and finding creative solutions. Let’s see if our efforts have paid off.
Increasing Airflow with a New Air Filter
Now we’ve got a metal one. I don’t know I guess later on, we’re gonna find out next up, we’ve got to put the air filter back on. However, this one here is so restrictive. Look at that! I’m not going to be getting much airflow going through that, so I’m gonna see if I can fit a lossy 5t1. Only trouble is, the body might not fit over it. It’s already catching on the exhaust, so we might have to cut a hole into the body this side and if that’s on there, I don’t know, we’ll see in a minute.
Trimming Plastic for a Better Fit
Exhaust on the inside, it’s kind of wedging over, though. We have to cut a bit of this plastic out here, also on that side. Oh man, we’re still rubbing. Let’s take a look. Hm, looks pretty good. I think we just need to trim a little piece out of here and boom, there we go, ready to whip.
Installing a Ziptail
Look to me, it looks like Zip tail fits really good on there. No, you’ve done that before, yeah? This was that exact one. The exact car, yeah, it’s gonna be built. It’s looking too good. Is that the standard tank? It’s pouring out, I was actually pouring out. I’m not leaking again from the same place as it all right. Turn it down. Applause! That’s got some power. Man, that is lively.
Stock Gearing and Performance
So the stock gearing for this engine really is a little bit on the low side.
A Disappointing Performance
When it comes to engine performance, there is always room for improvement. In the case of this particular engine, it seems that a little tweaking is necessary to unleash its full potential. While it may have an impressive amount of torque, its top-end speed leaves much to be desired. However, there is hope for the future as a possible solution to this problem is explored.
The Need for Better Gearing
One way to address the lackluster top-end performance is by adjusting the gearing. By finding a taller gear ratio, power can be better utilized to maximize speed. Although this may not significantly improve overall performance, it may make a noticeable difference in the engine’s top speed. Perhaps in a future video, this option will be explored further.
A Challenge to Overcome
In the meantime, a new challenge awaits. The task at hand is to navigate a field at full throttle, overcome a rugged mountain terrain, and make it through a narrow gap. The anticipation builds as the engine revs up, ready to tackle this daring feat.
A Sudden Setback
Unfortunately, things take an unexpected turn. Midway through the challenge, a mishap occurs. As the engine powers through the course, a critical component snaps, putting a halt to the excitement. The disappointment is evident as the blame game begins.
Rebuilding and Reflecting
Now faced with the daunting task of rebuilding the engine, frustrations run high. What was initially intended as a temporary modification turns into a full-blown restoration. It’s clear that more attention and care should have been given to ensure the engine’s longevity. Lessons are learned, and plans are made to prevent such mishaps in the future.
A Final Note
As the night falls and the engines are put away, it’s a moment to reflect on the ups and downs of the day’s adventure. Despite the setbacks, passion for engine performance remains unwavering. With a renewed determination, the engine enthusiasts set their sights on the next challenge, ready to conquer it with upgraded power and precision.
