Key Features
- 2-in-1 ESC and Receiver Integration — By combining the electronic speed controller and receiver into a single unit, this component reduces the overall electronics footprint in your vehicle, simplifies wiring complexity, and eliminates the need to install and secure two separate modules, making installation faster and your vehicle cleaner and more efficient.
- 40A Continuous Current Rating — The 40-amp capacity provides sufficient power delivery for brushed motor systems in ARRMA Mega and other compatible models, ensuring stable throttle response, smooth acceleration, and reliable performance during both casual bashing and more demanding use, whilst remaining well-suited to the electrical requirements of these vehicles.
- Switching BEC with 5V Output — The integrated switching battery eliminator circuit delivers a stable regulated 5-volt output, which is essential for powering your receiver and any servos connected to your vehicle, ensuring consistent signal reception and predictable servo operation across varying battery voltage conditions throughout your driving session.
- IC3 Connector Compatibility — The IC3 connector type ensures direct compatibility with ARRMA vehicles that use this standard connector configuration, allowing straightforward plug-and-play installation without the need for adapter cables or modifications to your existing wiring harness.
- 4mm Bullet Connectors for Motor — The 4mm bullet connectors provide secure, reliable motor connections with low electrical resistance, ensuring efficient power transfer to your brushed motor and allowing for quick disconnect and reconnect when swapping motors or performing maintenance.
- SLT Receiver Protocol — This receiver is specifically designed to work with SLT (Spektrum Long-Range Telemetry) transmitters, guaranteeing compatibility with modern Spektrum control systems and ensuring you have a genuine, matched receiver-transmitter combination for optimal signal reliability and control precision.
- Brushed Motor Compatibility — Engineered specifically to regulate and control brushed motor systems, this ESC is optimised for the electrical characteristics of brushed motors rather than brushless alternatives, providing appropriate power curves and control characteristics for these motor types.
- Replacement Component for Popular ARRMA Models — This unit is engineered as a direct replacement for the Granite Mega, Typhoon Mega, Fury, and Vorteks, so if you own one of these vehicles, you can be confident this component will fit and function exactly as intended without compatibility concerns.
Technical Performance
The SPM 40A Brushed 2-in-1 ESC and SLT Receiver V2 represents a thoughtfully engineered electronics solution that prioritises simplicity, reliability, and purpose-built compatibility for specific ARRMA vehicle platforms. At the heart of this unit is a 40-amp electronic speed controller capable of delivering consistent, stable power to brushed motor systems. The switching BEC (Battery Eliminator Circuit) operates at 5 volts and provides the necessary voltage regulation to keep your receiver and servo systems functioning reliably regardless of your main battery's state of charge during extended driving sessions. The IC3 connector interface used throughout this unit is the standard connection type found on compatible ARRMA vehicles, eliminating any need for adapters or workarounds. Motor power is delivered through industry-standard 4mm bullet connectors, which offer secure, low-resistance connections that maintain signal integrity and minimise voltage drop during operation. The integration of receiver and ESC functions into a single compact module is particularly valuable in vehicles with limited internal space, and the SLT receiver protocol ensures you're using genuine Spektrum technology with all the reliability and features that entails. Built to withstand the demands of RC vehicle operation, whether you're enjoying casual backyard bashing or taking your ARRMA vehicle to more challenging terrain, this 2-in-1 solution delivers the straightforward, dependable performance that RC enthusiasts across the UK have come to trust from Spektrum-engineered components.
