The CPS-1 is fully compatible with Futaba Ni-Cd and Ni-MH battery packs equivalent to 4–5 cells, making it versatile across a wide range of ready-to-run RC cars, trucks, and specialist vehicles available throughout the UK RC hobby market.

Key Features

• Ultra-compact design — At just 16 x 22 x 7.6 millimetres, the CPS-1 is small enough to fit into the tightest receiver bays and control enclosures, allowing you to optimise your RC vehicle's layout without sacrificing functionality or clean wiring.
• Lightweight construction — Weighing only 5.9 grams, this power switch adds virtually no weight penalty to your RC setup, making it ideal for applications where every gram counts, from scale crawlers to high-speed bashers.
• Reliable power management — The CPS-1 delivers consistent channel power control with a maximum output current of 200 milliamps or less, providing safe, regulated power distribution across your RC receiver's auxiliary channels without thermal stress.
• Low current drain — Drawing just 10 milliamps at 6.0 volts, the CPS-1 operates with exceptional efficiency, minimising battery drain and extending your RC vehicle's runtime on a single charge.
• Futaba battery compatibility — Designed exclusively for Futaba Ni-Cd and Ni-MH battery packs equivalent to 4–5 cells, ensuring perfect integration with Futaba receiver systems and eliminating compatibility guesswork.
• Voltage-flexible output — The output voltage automatically matches your receiver's power supply voltage, meaning the CPS-1 adapts seamlessly to your existing Futaba battery and receiver configuration without modification.
• Wide operating temperature range — Functioning reliably between ?10 and 45 degrees Celsius, the CPS-1 performs consistently whether you're running your RC vehicle in winter conditions or summer heat, making it suitable for year-round use.
• Professional-grade Futaba engineering — Built to the exacting standards that have made Futaba the trusted choice for professional RC pilots, competition modellers, and serious hobbyists across the UK and internationally.

Technical Performance

The Futaba CPS-1 Channel Power Switch is engineered with the precision and reliability that defines Futaba's reputation in the RC hobby. This compact module delivers clean, regulated power distribution with a maximum output current rating of 200 milliamps or less, making it suitable for controlling servos, receiver modules, and auxiliary electronics in custom RC setups. The switch draws a minimal 10 milliamps at 6.0 volts during operation, ensuring that your main battery capacity is used efficiently for driving your RC vehicle rather than powering the switching circuitry itself. Built specifically for integration with Futaba's receiver ecosystem, the CPS-1 accepts Ni-Cd or Ni-MH battery packs equivalent to 4–5 cells—a standard power configuration found across entry-level, intermediate, and professional RC vehicles throughout the UK and Europe. The output voltage dynamically matches your receiver's power supply, eliminating voltage regulation concerns and simplifying installation. Operating across a temperature range of ?10 to 45 degrees Celsius, the CPS-1 maintains consistent performance whether you're running your RC car on a cold winter's morning or during a hot summer session at your local RC track. The module's construction reflects decades of Futaba engineering excellence, with robust circuitry designed to withstand the demands of competitive driving, weekend bashing, and custom vehicle builds. The 16 x 22 x 7.6 millimetre footprint demonstrates Futaba's mastery of compact electronics design, allowing the CPS-1 to integrate seamlessly into space-constrained installations without compromising electrical performance or safety.

Frequently Asked Questions

• What is a channel power switch and why would I need one in my RC setup? — A channel power switch allows you to control the distribution of power to specific channels or auxiliary systems in your RC receiver. This is essential if you're running additional servos, lights, winches, or other electronics that require independent power management. The CPS-1 gives you precise control over when these systems receive power, improving reliability and extending battery life.
• Is the Futaba CPS-1 compatible with my Futaba receiver? — Yes, the CPS-1 is designed specifically for use with Futaba receivers and Futaba Ni-Cd or Ni-MH battery packs equivalent to 4–5 cells. If you're running a standard Futaba receiver system powered by a 4–5 cell Futaba battery pack, the CPS-1 will integrate seamlessly without modification.
• What battery does the CPS-1 need? — The Futaba CPS-1 requires a Futaba Ni-Cd or Ni-MH battery pack equivalent to 4–5 cells for power. These are the standard receiver batteries used in most Futaba RC systems. The switch will automatically output voltage matching your battery pack's supply voltage, so it works with any 4–5 cell Futaba battery without additional voltage regulation.
• How much current can the CPS-1 handle? — The CPS-1 is rated for a maximum output current of 200 milliamps or less, making it suitable for controlling servo channels, receiver modules, and light-duty auxiliary electronics. If you're planning to power high-current devices like winches or powerful motors, you'll need a dedicated ESC or power controller rated for higher current.
• What's the current drain when the CPS-1 is operating? — The CPS-1 draws only 10 milliamps at 6.0 volts during operation, which is minimal compared to typical receiver battery capacities. This low current draw means the switch itself has virtually no impact on your RC vehicle's runtime.
• Will the CPS-1 work in cold or hot weather? — Yes, the CPS-1 is rated to operate reliably across a temperature range of ?10 to 45 degrees Celsius. This makes it suitable for year-round use, whether you're running your RC vehicle during winter drives or summer competition sessions.
• Is this suitable for beginners? — The CPS-1 is an intermediate to advanced component recommended for modellers who are comfortable with receiver wiring and custom RC builds. Beginners running ready-to-run RC vehicles typically won't need a channel power switch unless they're expanding their receiver's capabilities with additional servos or electronics.
• How compact is the CPS-1? — The CPS-1 measures just 16 x 22 x 7.6 millimetres (excluding any protruding connectors) and weighs only 5.9 grams, making it one of Futaba's most space-efficient power control solutions. This compact design allows it to fit into tight receiver compartments and modular installations where space is critical.
