Frequently Asked Questions
- What ARRMA models is this motor plate set compatible with? — The ARRMA Motor Plate Set Z-ARA-2598 is specifically designed for and compatible with all ARRMA 1/16 GORGON GROM 4x4 ready to run brushed monster trucks (Yellow, Bronze and Red variants) and the ARRMA 1/16 QUAKE GROM 4x4 ready to run brushed monster trucks (Purple, Green and Red variants). If you own one of these GROM models, this motor plate set is the correct replacement or upgrade component.
- Why would I need different motor plates with various pinion sizes? — Different pinion sizes allow you to adjust your vehicle's gear ratio, which directly affects acceleration, top speed and overall performance characteristics. A smaller pinion provides faster acceleration but lower top speed, whilst a larger pinion delivers higher top speed but reduced acceleration. By having nine plate options with dual pinion combinations, you can fine-tune your GROM to match your preferred driving style, the terrain you're running on, or specific race requirements.
- What makes composite motor plates better than plastic alternatives? — Composite material offers superior durability and longevity compared to standard plastic components. The material is engineered to maintain dimensional stability through extended use, resist wear from repeated mounting and unmounting, and withstand the physical stresses of RC driving without degradation. This means your investment in this motor plate set will provide reliable performance across many seasons of use.
- Is this suitable for beginners? — Yes, this motor plate set is suitable for beginners who own an ARRMA GROM ready to run RC car. The installation process is straightforward, involving securing the plate to your chassis with the included fasteners. The indexed design ensures correct alignment without requiring specialist tools or technical knowledge. Beginners may start with a standard configuration and explore different gear ratios as they gain experience and understand how changes affect performance.
- What is the indexed design and why does it matter? — The indexed design refers to precisely machined slots or mounting positions on each motor plate that ensure accurate, repeatable motor positioning relative to the chassis. This precision engineering is critical because even small variations in motor position can affect pinion-to-gear mesh, which influences power delivery, efficiency and longevity. The indexed design guarantees consistent performance regardless of how many times you swap between plate configurations.
- Do I need any special tools to install these motor plates? — Installation requires only basic tools such as a screwdriver or hex key suitable for the cap head screws provided. No specialist tools or equipment are necessary, making this an accessible upgrade or replacement option for RC enthusiasts of all experience levels.
