MEUS RACING Servo Mount Only – Aluminum, CNC, for AR44/AR45/Capra Axles (SOA/BTA)

This aluminum servo mount from MEUS RACING is designed for 1/10 scale nylon straight axles with 194mm or 224mm wheel distance, including AR44, AR45, and Capra Isokinetic axles. It supports both Servo On Axle (SOA) and Behind The Axle (BTA) mounting and lets you switch between them without drilling or modifying the axle.

How Does an Aluminum Servo Mount Improve Steering?

Stock plastic servo mounts can flex under load, which reduces the accuracy of steering inputs. This mount is CNC machined from aluminum, giving it much higher stiffness. The precise machining ensures that the servo sits flat and the mounting holes line up exactly, reducing slop and binding in the steering linkage. Many users notice a more consistent and crisp steering response, especially on technical rock sections where every degree of steering matters.

SOA vs BTA: Which Mounting Option Fits Your Setup?

With SOA (Servo On Axle), the servo sits directly above the axle centerline, keeping weight low and centered. BTA (Behind The Axle) moves the servo behind the axle, which can alter the steering arc and reduce bump steer. The mount is designed so you can switch between the two without any permanent changes to the axle – just reposition the servo and screws. This flexibility is helpful if you experiment with different chassis roll centers or suspension geometry.

Installation and Compatibility Details

This mount is a direct replacement for the factory plastic servo mount on compatible MEUS axles. It comes as a single machined piece – you reuse your existing servo screws and axle hardware. No drilling, tapping, or permanent changes to the axle are required. The mount itself weighs under an ounce, so it adds minimal unsprung weight. Note: This is the mount only, no servo included.

Frequently Asked Questions

Does this mount fit other axle brands?

The manufacturer specifies compatibility only with MEUS 194mm/224mm wheel distance AR44, AR45, and Capra Isokinetic nylon straight axles. It may not fit other brands or different wheel distances without modification.

Is the servo included?

No, this is the mount only. You will need a standard size servo (not included) to complete the installation.

Can I use this on a Capra axle?

Yes, the Capra Isokinetic axle is listed as compatible. Ensure your wheel distance is either 194mm or 224mm to match the mount’s design.

What tools are needed for installation?

Basic hex drivers to remove the existing mount screws and attach the servo. No special tools required.
