The Secret Traxxas VXL Brushless Truth That Will Change RC Forever!
Have you ever stared at your Traxxas Slash, feeling it’s almost perfect, but that nagging thought remains: “What secret are the top racers hiding?” The whispers are true. There’s a transformative upgrade, a piece of “secret sauce” so potent it doesn’t just improve your RC—it redefines what you thought was possible on the track or in the dirt. We’re talking about the Traxxas VXL Brushless system, and the truth about its integration is the game-changer every enthusiast needs to understand.
This isn't just about swapping a motor. It's a complete philosophy shift in how you approach power, gearing, and thermal management. The journey from a stock setup to a VXL-powered beast is paved with insights that many spend years discovering. Let’s pull back the curtain, using a series of revelations—some from the track, some metaphorical—to build the ultimate guide to this transformation.
The "Secret Sauce" Analogy: Why the VXL System is the Game-Changer
“I wonder if Grubb is the secret sauce that made DeBoer.”
This quote, likely from a sports forum, perfectly captures a universal truth in competitive fields: one pivotal, high-quality element can elevate an entire system. Think of Coach DeBoer’s success. Now, translate that to your RC. Your Slash is the team. Your electronics are the coaching staff. And the Traxxas VXL Brushless motor and ESC combo? That’s your “Grubb”—your irreplaceable secret sauce.
A stock brushed motor is like a competent, reliable assistant coach. It gets the job done. But the VXL system is the visionary head coach who changes the entire playbook. It delivers not just more power, but smarter, more efficient, and more controllable power. The “secret” isn’t just the hardware; it’s the synergy it creates with every other component, especially your gearing.
Understanding the Landscape: The "Portal" of RC Upgrading
“10,965 NCAA football players entered the portal.”
This staggering number represents a mass migration toward better opportunities. In the RC world, we have our own “portal”—the constant stream of hobbyists moving from stock brushed systems to brushless, and specifically to the VXL platform. The reason? Performance ceilings. Stock systems hit a wall. Heat, inefficiency, and limited torque cap your fun.
The VXL system is the scholarship offer to a top-tier program. It’s an invitation to a higher level. But simply “entering the portal” (buying the parts) isn’t enough. You must understand the new playbook (gearing, battery, cooling) to succeed. This article is your recruiting guide, your playbook, and your insider’s look at what works.
The Insider’s List: Seniors with Significant Playing Time (The Proven VXL Setups)
“Herzog | secrant.com not that this is secret, but here is the list of seniors with significant playing time.”
In any community, the “seniors” are the veterans with thousands of laps logged. They’ve tried the failures and found the winners. While there’s no single “list,” the consensus among these veterans for a Traxxas Slash with a VXL system is clear and forms the backbone of our recommendations.
The Proven Baseline for a Traxxas Slash 2WD VXL Conversion:
- Motor: Traxxas Velineon VXL-3s Brushless Motor (3500kV or 4000kV depending on desired top speed vs. torque).
- ESC: Traxxas VXL-3s Electronic Speed Control (often purchased as a combo).
- Battery: 2S or 3S LiPo (e.g., Traxxas Power Cell 5000mAh 2S or 3S). Start with 2S for manageability.
- Gearing: This is the critical variable. Stock gearing (e.g., 16/90) is a starting point, but not the finish line.
“So long to them & good luck.”
This is the veteran’s farewell to their old, overheated brushed motors and inefficient setups. You’ll be saying this too, once you feel the VXL difference.
Decoding the Gearing Trinity: The Heart of the Secret
This is where the magic—and the science—happens. The VXL motor’s potential is locked behind a gear ratio. Unlock it correctly, and you have a weapon. Get it wrong, and you have a very expensive paperweight that smells like burnt plastic.
“How gearing works the best place to start is always the manufacturer's stock, or default, gearing set up.”
Absolutely correct. For the Traxxas Slash, stock gearing is typically a pinion gear around 16T and a spur gear around 90T (16/90). This is your baseline. It’s designed for the stock brushed motor’s power band and thermal limits.
“I have the traxxas slash 2wd with 16/90 gearing with ‘optional gearing 23/86’ which i tried and motor ran hot so i upgraded to the vxl brushless motor and put the 16.”
This is the critical learning moment. The user tried a taller gear ratio (23/86 gives a higher top speed) on a stock motor and cooked it. The VXL motor, with its vastly superior efficiency and torque handling, can actually use that taller gearing without overheating—in fact, it thrives on it.
The Gearing Secret Formula:
- Pinion Gear (Small): The driver. More teeth = more speed, less torque/acceleration, more motor heat.
- Spur Gear (Large): The driven. Fewer teeth = more speed, less torque/acceleration, more motor heat.
- Final Ratio = (Spur Gear Teeth / Pinion Gear Teeth) * Transmission Ratio.
- For Slash 2WD, Transmission Ratio ≈ 2.17.
- Example: Stock 16/90: (90/16) * 2.17 = ~12.2 Final Ratio.
- "Optional" 23/86: (86/23) * 2.17 = ~8.1 Final Ratio. This is a much taller (faster) ratio.
The VXL Truth: Your VXL motor can handle a taller gear ratio than your old brushed motor. Start with your stock 16/90 on the VXL. It will feel dramatically faster and cooler. Then, experiment by increasing the pinion size (17T, 18T, 19T) or decreasing the spur size (87T, 86T) in small increments. Listen to the motor temperature and feel the acceleration. Your goal is the highest gear ratio (tallest gears) your motor can handle without getting excessively hot (touch-test: warm, not painful) after a 5-minute run.
Practical Speed Secrets for Your Traxxas Slash VXL
“In this episode we go over a couple speed secrets for the traxxas slash to help get more speed out of your dirt oval traxxas and buggy cars. I say buggy cars as well because the speed secret #1.”
The principles apply to any 1/10th scale Traxxas vehicle with a VXL system. Here are the actionable secrets:
1. The Thermal Management Imperative: The VXL system is efficient, but pushing it hard in a heavy Slash on a dirt oval generates heat. Secret: Ensure your motor has maximum airflow. Remove any unnecessary body clips or braces that block the motor’s cooling fins. Consider a small, 30mm fan mounted to blow directly on the motor after a run (not during, to avoid debris).
2. The Battery Connection: A weak or old LiPo battery sags under the VXL’s demand, making the motor work harder and generate more heat. Secret: Use a high-C rating (50C or higher), well-maintained LiPo. A fresh, powerful battery delivers consistent voltage, allowing the ESC to operate efficiently and the motor to run cooler.
3. Mechanical Efficiency: Bearings, drivetrain drag, and tire choice matter. Secret:Upgrade to all bearings (especially in the transmission). Lubricate gear sets with a light, non-corrosive RC gear lube. For oval racing, use slick, low-traction tires to reduce drag. For buggies, choose the right compound for the surface.
4. The “Secret” Tuning: Throttle & Brake Profiles: Your Traxxas VXL-3s ESC is programmable via the Traxxas Link app. Secret: Don’t use the default “Race” profile for bashing. Create a custom profile with:
* Lower Brake Force: Reduces drivetrain shock.
* Adjusted Drag Brake: A small amount (5-10%) can help cornering on dirt.
* Throttle Curve: A slightly progressive curve can help manage wheelspin off the line.
Addressing the "Site Won’t Allow Us" & Other Mysteries
“We would like to show you a description here but the site won’t allow us.”
This internet relic reminds us that valuable information can be hidden behind technical walls. In the RC world, the real “secret” knowledge isn’t always on the main product pages. It’s in forum threads, YouTube comments from seasoned racers, and local track gossip. Seek out the communities (like the official Traxxas forums, RC Groups, or specific Slash Facebook groups). The “site” of true knowledge is the collective experience of the community.
“Where is the irons puppet super secret list of auburn head coach candidates”
This bizarre sports reference highlights the human hunger for insider, “secret” lists. In RC, the “super secret list” is the real-world, tested gearing combinations for specific tracks and conditions. There is no master list because every track, every battery, every temperature is different. You must build your own list through systematic testing. Start with the veteran recommendations (e.g., 17/86 for a good balance on a medium-bite dirt track) and log your results.

While this seems unrelated, it speaks to the global passion for automotive engineering and modification. The spirit of tuning a Japanese supercar is the same as tuning a Traxxas Slash: extracting every ounce of potential through understanding and modification. The VXL system is your entry into that world of high-performance engineering, scaled down.
Actionable Implementation: Your 5-Step VXL Transformation Plan
- Acquire the Core: Purchase the Traxxas Velineon VXL-3s Combo. Ensure it’s compatible with your Slash model.
- Install & Initial Test: Install it with your stock 16/90 gearing. Use a 2S LiPo. Run the truck. Note the incredible difference in power and the lack of the old motor’s heat smell.
- The First Gear Leap: Change your pinion to a 17-tooth (keep the 90-tooth spur). Run again. Feel the increased top speed. Check motor temperature after a run. If it’s only warm, you’re on the right track.
- Systematic Tuning: Change one variable at a time. Next, try an 18T pinion. Then, try a 17T pinion with an 87T spur (same ratio as 18/90, but different tooth engagement). Keep a logbook: Date, Track Conditions, Gearing, Motor Temp (hand-touch scale: Cool/Warm/Hot), Battery Used, Performance Notes.
- Optimize the Ecosystem: Once you find your ideal gearing, address the other “secrets”: fresh bearings, proper lubrication, a high-C battery, and a custom ESC throttle/brake profile.
