RCEXL Twin Cylinder Ignition – 120° CM-6 / 10mm Spark Plug Cap (14mm Hex)
Take control of your twin-cylinder RC engine’s performance with the RCEXL 120° Twin Cylinder Ignition System, built for engines using CM-6 / 10mm spark plugs with 9/16" (14mm hex) caps. The 120-degree angled spark plug caps provide flexible installation options, making it ideal for tight engine bays or custom setups.

This high-performance CDI unit is designed for twin-cylinder engines and supports a wide voltage range from 6V to 14.4V. It includes Futaba female connectors for both battery and tachometer integration, and features a smart ignition curve that enhances startup, throttle response, and top-end power.

With automatic timing retard for smoother starts and dual-spark firing at low RPM, this unit ensures consistent ignition and improved engine reliability.

Specifications:

  • Engine Compatibility: Twin-cylinder RC gas engines

  • Spark Plug Compatibility: CM-6 / 10mm (14mm Hex)

  • Plug Cap Angle: 120 degrees

  • CDI Unit Weight: 178g

  • Operating Voltage: 6V – 14.4V

  • Connectors: Futaba Female (Battery & Tachometer)

  • Recommended Timing: 30° BTDC

  • Startup Timing: Automatically retards to 20° BTDC (100–2000 RPM)

  • Timing Curve: Dynamic until 4000 RPM, then fixed at 30° BTDC

  • Start Assist: Fires spark plug twice per cycle for easier ignition

Note:
BTDC stands for Before Top Dead Centre—critical for accurate ignition timing.

Perfect for model aircraft builders who require advanced ignition control, cleaner starts, and smooth power delivery in twin-cylinder configurations.
