The Traxxas TRX4M is a popular and capable scale crawler, but its stock servo placement can sometimes be a limiting factor. Upgrading to a lay down servo mount offers significant advantages, improving performance and aesthetics. This guide will explore the benefits, installation process, and considerations for choosing the right lay down servo mount for your TRX4M.
Why Choose a Lay Down Servo Mount?
A lay down servo mount repositions your servo from its vertical orientation to a horizontal position, laying it down alongside the chassis. This seemingly small change offers several key benefits:
-
Improved Clearance: The primary advantage is increased ground clearance. The stock servo placement can sometimes hinder articulation, especially when tackling challenging obstacles. By moving the servo lower and out of the way, you significantly reduce the chance of it getting snagged or damaged.
-
Better Weight Distribution: Lowering the center of gravity (CG) by relocating the servo improves the TRX4M's stability and handling. This translates to smoother crawling and better control, especially on uneven terrain.
-
Increased Steering Responsiveness: With the servo closer to the steering linkages, you can achieve quicker and more precise steering responses. This enhancement is particularly noticeable at slower speeds, aiding in precise maneuvering.
-
Aesthetic Enhancement: Let's be honest, a lay down servo mount often improves the overall look of the TRX4M. It creates a cleaner, more streamlined appearance, enhancing the scale realism.
Choosing the Right Lay Down Servo Mount
The market offers various lay down servo mounts for the TRX4M, each with its own features and design. Consider these factors when making your selection:
-
Material: Aluminum is a popular choice for its strength and durability, while plastic options provide a lighter alternative. Aluminum mounts generally offer better rigidity.
-
Servo Compatibility: Ensure the mount is compatible with the size and dimensions of your servo. Measure your servo carefully before purchasing to avoid compatibility issues.
-
Mounting Points: Some mounts utilize the stock servo mounting locations, while others may require drilling additional holes. Check the product description for detailed information regarding installation requirements.
-
Additional Features: Some advanced mounts offer features like built-in linkage adjusters or provisions for mounting other accessories.
Installing Your Lay Down Servo Mount
The installation process can vary slightly depending on the specific mount you choose. However, general steps typically include:
-
Remove the Stock Servo: Carefully remove the stock servo from the TRX4M. Take note of the wiring connections for reassembly.
-
Prepare the Mount: Depending on the design, you may need to adjust or prepare the mount. This might involve attaching linkages or pre-drilling holes.
-
Mount the Servo: Securely attach the servo to the new lay down mount.
-
Attach the Mount to the Chassis: Install the mount to the TRX4M chassis, following the manufacturer's instructions carefully. Ensure the mount is securely fastened.
-
Reconnect the Wiring: Reattach the servo's wiring, making sure it's properly connected and routed to avoid interference.
-
Test and Adjust: After installation, test the steering and make any necessary adjustments to the linkages for optimal performance.
Conclusion
Upgrading to a lay down servo mount is a worthwhile modification for any TRX4M owner seeking improved performance and a cleaner aesthetic. By carefully selecting a compatible mount and following the installation instructions, you can significantly enhance your crawling experience. Remember to always prioritize safety and ensure all components are securely fastened. Happy crawling!
