High-Torque Emax Servos: The Ultimate Upgrade for SCX24 & Micro Flyers
Whether you are trying to fix the vague steering on your Axial SCX24 or looking for a reliable emax 9g servo for a lightweight park flyer, Emax delivers the best torque-to-weight ratio in the industry. From the legendary emax es08ma ii 12g mini metal gear analog servo to the ultra-precise emax digital servo range, these units provide the centering accuracy and durability that stock plastic servos simply can’t match.

Step-by-Step: Installing an Emax Servo in an Axial SCX24
Upgrading to an axial scx24 emax servo is the single most popular mod for crawlers. Follow these steps to ensure you don’t fry your electronics:
Mounting: Most emax es08ma ii servo units require a specific mounting tray. Do not force it into the stock plastic mount.
Linkages: Use high-quality steering links and brass knuckles to handle the increased torque of the emax 12g servo.
Centering: Power on your ESC and set your transmitter trims to zero before attaching the servo horn.
Tools: Ensure you have precision hex drivers from our Drone Tools collection to avoid stripping the small internal screws.
Common Issues & Pro-Tips (From the Community)
Based on veteran feedback from Reddit and FPV forums, here is what you need to watch out for:
The “Burning Smell” Warning: If you plug in your emax es08a micro servo and the ESC gets hot or smells like burning, check your wiring immediately. Some older ESCs struggle with the current draw of metal gear servos, which can lead to motor inactivity or a fried BEC.
Stripped Horns: A common mistake is trying to force a metal horn onto an emax 9 gram servo without checking the spline count. If it doesn’t slide on smoothly, don’t force it, or you’ll strip the internal gears.
Voltage Sag: While many emax digital servo models are high-voltage compatible, running them at the limit on a long wheelbase chassis can cause brownouts if your battery C-rating is too low.
Frequently Asked Questions
What is the maximum voltage for Emax servo?
Most modern Emax servos are High Voltage (HV) compatible, able to run on voltages from 5V to 8.4V (2s LiPo). This provides significantly more torque and faster response times across the board.
What is the difference between a 180 and 270 servo?
The main difference is the range of motion. An emax 3352 servo or similar 180-degree model rotates half a circle, while a 270-degree servo is typically used for specialized robotics or pan-and-tilt camera mounts requiring a wider sweep.
Is EMAX a Chinese company?
Yes, EMAX is a leading high-tech enterprise based in China, focusing on the design and manufacturing of FPV racing components, including motors, ESCs, and their world-renowned emax 9g metal gear servo line.
Why is my Emax servo twitching?
Twitching is usually caused by signal interference or insufficient power. Ensure your emax es08ma ii analog servo is not sharing a power rail with a high-draw VTX, and check that your ground wires are securely soldered.
