Technical Performance

The ARRMA Metal Slipper Power Module BOOST Box represents a significant engineering step forward in drivetrain capability for 1/10 scale RC bashers. The assembled brushless power module has been engineered from the ground up to handle the substantially higher torque and sustained power delivery that brushless motor systems provide, compared to the standard brushed motors these vehicles ship with. The inclusion of a metal slipper clutch is particularly important for brushless upgrades, as the dramatically increased acceleration and motor responsiveness of brushless systems can create drivetrain shock loads that destroy transmission components within seconds if inadequate protection is in place. The slipper clutch uses a friction-based slip mechanism that allows controlled wheel spin during hard launches and impacts, protecting the gears, bearings and shafts from catastrophic failure. The three included pinion gears (15T, 18T, and 20T) allow you to fine-tune your final drive ratio based on your specific vehicle model and driving environment. Smaller pinion teeth (15T) deliver higher top speeds but require more motor torque, making them suitable for low-grip surfaces and high-powered setups, whilst larger pinions (20T) provide better acceleration and lower top speeds, ideal for tight courses and less powerful motor configurations. The power module itself is constructed from premium materials designed to withstand the sustained performance demands of brushless RC driving, with precision-engineered gear meshes and robust bearing support systems. The modular design allows you to seamlessly integrate your choice of 1/10 scale brushless motor and ESC without compatibility issues, provided the components match standard 1/10 scale pinion sizing and mounting conventions. ARRMA's engineering team has validated this setup across the entire BOOST vehicle range, ensuring the power module's design is optimised for the weight distribution, chassis geometry and suspension characteristics of these specific models. The brushless upgrade typically delivers 2-3 times the power output of the standard brushed motor setup, translating to dramatically faster acceleration and sustained high-speed performance, though actual top speed will depend on your specific motor KV rating, battery voltage and ESC programming.

Frequently Asked Questions

• Which ARRMA vehicles are compatible with the Metal Slipper Power Module BOOST Box? — This upgrade kit is designed for ARRMA 4X2 BOOST vehicles, specifically the GRANITE BOOST, SENTON BOOST and VORTEKS BOOST models in both battery and non-battery variants. The kit is also compatible with selected ARRMA 4X4 MEGA vehicles. Check the full compatibility chart included in the product manual to confirm your specific model is supported before purchasing.
• Do I need any special tools or technical knowledge to install this upgrade? — While basic RC car maintenance knowledge is helpful, ARRMA has made installation accessible by providing a step-by-step online video guide accessible via QR code. Following this video tutorial carefully will guide you through each installation step, though you will need standard RC hobby tools like hex keys, screwdrivers and possibly a gear mesh tool. If you're completely new to RC car maintenance, we recommend having an experienced hobbyist assist with your first installation or visiting an RC hobby shop for professional installation services.
• What brushless motor and ESC should I choose to go with this upgrade kit? — This is entirely up to your preferences and driving style. For general high-speed bashing, popular choices include brushless motors in the 3660 to 4074 size range with KV ratings between 2000-4000 depending on your battery voltage and desired top speed. Match your ESC to your motor's power rating; a 120A ESC is typical for entry-level brushless setups, whilst 150A+ units suit more powerful configurations. Consult with your local RC hobby retailer to find the right motor and ESC combination for your vehicle and budget.
• Will this upgrade significantly improve the speed of my ARRMA BOOST vehicle? — Yes, brushless upgrades typically deliver 2-3 times the power output compared to standard brushed motors, resulting in much faster acceleration and higher sustained speeds. Your exact top speed will depend on your specific motor KV rating, battery voltage, chosen pinion gear and ESC programming, but most users report their BOOST vehicles reaching 40+ mph after a brushless upgrade, compared to the 30+ mph capability of the standard brushed setup.
• Can I use my existing ARRMA battery and charger with this brushless upgrade? — This depends on your battery type and the ESC you select for your brushless setup. If you have a Spektrum Smart Battery, it may be compatible, but you must verify voltage compatibility with your chosen brushless motor and ESC. We recommend consulting with an experienced RC enthusiast or your local hobby shop to confirm battery compatibility before purchasing your motor and speed controller, as incorrect battery voltage can damage components or create safety hazards.
• Is the Metal Slipper Power Module BOOST Box suitable for a beginner to RC cars? — This upgrade kit is best suited to intermediate RC hobbyists who already have experience maintaining and modifying RC vehicles and understand brushless motor and ESC concepts. Complete beginners are better served by purchasing a ready-to-run RTR vehicle first and developing foundational RC skills before tackling brushless upgrades. However, if you're comfortable following detailed instructions and have access to online tutorials and local hobby support, this kit can work for determined learners willing to take their time during installation.
• Why does this kit include three different pinion gears? — Different ARRMA BOOST models (GRANITE, SENTON and VORTEKS) have different tyre diameters, which affects how many wheel rotations occur per motor rotation. The three pinion options (15T, 18T, 20T) allow you to select the correct gear ratio for your specific vehicle to ensure optimal performance, proper gear meshing with the spur gear, and to match your desired top speed and acceleration characteristics. Using the wrong pinion can result in poor performance or excessive wear.
• What is a metal slipper clutch and why is it important for brushless upgrades? — The slipper clutch is a friction-based component that allows the motor to continue spinning even when the wheels have reached maximum grip or hit an obstacle, slipping to prevent damage to the drivetrain. This is particularly important with brushless motors because they deliver much higher torque very suddenly, which can break transmission components instantly without the protection a slipper clutch provides. The metal construction of this slipper clutch offers excellent durability and consistent slip characteristics under the extreme demands of brushless power.
