Overview
The Traxxas Plate, motor (TRX3997X) is a premium blue-anodised aluminium motor plate designed specifically for converting your E-Maxx RC vehicle from a dual motor setup to a single brushless motor installation. If you're looking to upgrade your RC car UK with brushless power, this component makes the transition seamless and straightforward. The E-Maxx was engineered from the ground-up to handle extreme brushless torque and power, and this motor plate is the key to unlocking that potential with your favourite electric power plant.
Traxxas makes it incredibly easy to swap from dual motors to a high-performance single brushless motor setup. Rather than dealing with complex modifications and compromised fit, you simply bolt in this precision-engineered aluminium plate alongside the matching single motor gear cover (#3977R) to achieve a clean, factory-finish installation. Whether you're a weekend basher looking to maximise your ready to run RC experience or an experienced enthusiast seeking to customise your brushless RC setup, this plate delivers professional-grade results without the headache of custom fabrication.
The aluminium construction ensures durability whilst keeping weight to a minimum—critical factors for maintaining the E-Maxx's legendary performance credentials. This is not a compromise component; it's a genuine Traxxas factory solution that gives your brushless installation the structural integrity and aesthetic appeal of a purpose-built system. Perfect for anyone serious about getting the most from their brushless RC car, this motor plate represents the kind of attention to detail that has made Traxxas a trusted name in the RC hobby across the UK and beyond.
Key Features
- Blue-Anodised Aluminium Construction — The plate is manufactured from high-grade aluminium with Traxxas's signature blue anodising, which not only looks fantastic but provides excellent corrosion resistance and durability for long-term use in demanding RC conditions.
- Dual-to-Single Motor Conversion — This plate enables you to convert your E-Maxx from a factory dual motor configuration to a single brushless motor setup, giving you the flexibility to choose your own favourite electric power plant and install it with confidence.
- Factory Fit and Finish — The precision engineering ensures a clean, professional appearance with a true factory fit, meaning your brushless installation looks as if it came straight from Traxxas rather than being a third-party modification or custom fabrication.
- Compatible with Gear Cover #3977R — The motor plate is designed to work seamlessly with the Traxxas single motor gear cover #3977R, and together these components create a complete, integrated single motor installation system that maintains the original E-Maxx aesthetics.
- Engineered for Extreme Power — Since the E-Maxx was designed from the ground-up to handle extreme brushless torque and power, this plate is engineered to support the full performance envelope of modern brushless motors without compromise or flex.
- Easy Bolt-In Installation — Rather than requiring complex fabrication or modification, this plate simply bolts into place using existing E-Maxx mounting points, making the conversion process accessible to RC enthusiasts of varying skill levels.
Technical Performance
The Traxxas TRX3997X motor plate represents a significant engineering achievement in RC car customisation. Manufactured from premium aluminium and finished in Traxxas's distinctive blue anodised coating, the plate combines lightweight construction with exceptional rigidity—essential when handling the extreme torque and power output of modern brushless motors. The E-Maxx platform was specifically engineered to accommodate brushless powertrains with their dramatically higher torque characteristics compared to the original brushed motor systems, and this single motor plate fully leverages that design philosophy. The precision machining ensures perfect alignment of your brushless motor, critical for proper gear mesh, reduced vibration, and reliable long-term operation. Whether you're running a high-KV brushless motor for speed-focused bashing or a lower-KV setup optimised for torque delivery and crawling performance, this plate provides the structural foundation your installation demands. The anodised finish protects against corrosion from moisture and salt (particularly relevant for UK RC enthusiasts using their vehicles near coastal areas or in damp conditions), whilst the blue colour coordinates perfectly with other Traxxas components, maintaining the professional appearance of your E-Maxx platform.

Frequently Asked Questions
- Which E-Maxx models does the TRX3997X motor plate fit? — This motor plate is compatible exclusively with E-Maxx model 3905 and model 3903 only. If you own a different generation or variant of the E-Maxx, please verify your model number before purchasing to ensure compatibility.
- Do I need anything else to complete the single motor installation? — Yes, you'll need the matching Traxxas single motor gear cover #3977R to complete the installation. Together, these two parts create the complete single motor conversion system. You'll also need to source your own brushless motor, brushless ESC, and LiPo battery, allowing you to choose the exact power characteristics that suit your driving style.
- What makes this better than a universal motor plate? — This is a genuine Traxxas factory component engineered specifically for the E-Maxx platform, which means it's designed with exact knowledge of the mounting points, chassis geometry, and stress distribution of your vehicle. This precision fit and engineering eliminates the compromises and fitment issues often associated with universal aftermarket plates, and gives you that authentic factory-quality finish that serious RC enthusiasts demand.
- Can I use any brushless motor with this plate? — The plate itself is a passive mounting component that will accept any standard brushless motor with compatible mounting holes. However, the choice of motor will dramatically affect your vehicle's performance. Consider whether you want high speed (high-KV motor) or high torque (low-KV motor), and ensure your ESC and battery are rated appropriately for the power output of your chosen motor.
- Is this suitable for beginners? — While the plate itself is straightforward to install, converting from dual motors to single motor and selecting compatible brushless components requires some RC knowledge. Beginners are welcome to attempt this upgrade, but we recommend consulting with our experienced team at RC Model Shop who can guide you through choosing the right motor, ESC, and battery combination for your specific needs and driving style.
- What is the difference between the dual motor E-Maxx setup and single motor setup? — The factory dual motor E-Maxx distributes power across two motors for balanced acceleration and handling characteristics. A single brushless motor setup concentrates all power through one larger, high-performance brushless unit, typically delivering superior overall speed and torque. The single setup also reduces electrical complexity, weight, and cost, whilst maintaining full control and reliability—making it an excellent choice for those seeking maximum performance from their E-Maxx platform.
