The RCEXL LV Inline Twin Cylinder Ignition CDI is a high-performance solution for petrol-powered RC engines, engineered to deliver precise ignition timing and dependable performance in demanding conditions. Designed by a professional CDI manufacturer, this system incorporates advanced microprocessor-controlled timing to ensure optimal spark delivery across the full throttle range.

Featuring an automatic advancing ignition angle, the system continuously adjusts timing for improved combustion efficiency, smoother engine operation, and enhanced throttle response. The capacitive discharge ignition (CDI) technology provides a strong and stable spark, while the fully shielded design helps minimise electrical interference—ideal for sensitive RC setups.

This LV (low voltage) ignition system operates within a 6.0V–12V range and is compatible with NGK ME-8 1/4-32 spark plugs. The included 90-degree spark plug caps (8mm hex) make installation easy, even in tight engine bays, offering both convenience and reliability.

Whether you're flying large-scale aircraft or running high-performance petrol engines, RCEXL delivers trusted ignition performance every time.
