Power Up Your RC Aircraft: A Complete Guide to RCEXL Ignition Systems
If you’re running petrol or gas engines in your RC aircraft, you know that reliable ignition is absolutely critical. A missed spark at the wrong moment can mean the difference between a smooth flight and an emergency landing. That’s where RCEXL ignition systems come in, offering professional-grade performance for both hobbyists and serious RC enthusiasts.
What Makes RCEXL Ignition Systems Stand Out?
RCEXL has built a solid reputation in the RC community for producing ignition systems that deliver consistent, powerful sparks across a wide range of engine configurations. These systems are designed specifically for RC petrol and gas engines, with features that address the unique challenges of model aircraft applications.
The standout feature? Versatility. RCEXL ignition systems work with both single-cylinder and multi-cylinder engines, and they’re compatible with multiple spark plug types. Whether you’re flying a smaller single-cylinder engine or a giant scale warbird with a multi cylinder radial or boxer, there’s an RCEXL system configured for your setup.
Universal Voltage Compatibility
One of the most practical features of RCEXL ignitions is their voltage flexibility. These systems operate on 6 to 14.4 volts, which means they work seamlessly with the most common battery configurations in the RC world:
- 5-cell NiMH batteries
- 2S LiPo batteries
- 3S LiPo batteries
This flexibility eliminates the need for voltage regulators or special battery packs. You can use the same battery system that powers your servos and receiver to run your ignition, simplifying your aircraft’s electrical setup and reducing overall weight.
Single and Twin Cylinder Options
RCEXL offers dedicated ignition systems for both single and twin-cylinder engines, with the twin-cylinder units featuring their Version 2 design for improved performance and reliability.
Single Cylinder Systems are perfect for engines ranging from small 10cc units up to larger singles in the 60cc range. They provide a strong, consistent spark that ensures reliable starting and smooth running throughout the RPM range.
Twin Cylinder Systems are specifically engineered to fire two cylinders with precise timing. The Version 2 twin ignitions feature improved electronics that maintain consistent spark energy even at high RPMs, which is crucial for larger displacement engines that power giant scale aircraft.
Availability We can obtain most of not all RCEXL ignitions from single cylinder systems through multi cylinder options plus some of those harder to get parts such as replacement caps and ignition sensors for a range of engines.

Comprehensive Cap Angle and Plug Type Selection
Not all engines are created equal, and RCEXL recognizes this by offering ignition systems with different cap angles and plug compatibility:
Cap Angles:
- 90° angle caps for tight installations
- 120° angle caps for specific engine configurations
- Straight caps for maximum clearance
Plug Types:
- ME-8 1/4-32 thread (common on many popular engines)
- CM-6 10MM thread (used on various Asian-made engines)
- BMR6F 14MM thread (standard automotive-style plug)
- BMR6A 14MM thread (alternative automotive plug specification)
This variety ensures that virtually any petrol or gas RC engine can be fitted with an RCEXL ignition system. The different model numbers (ranging from 1121 to 1228) correspond to specific combinations of single/twin configuration, plug type, and cap angle.
Installation and Compatibility
RCEXL continues to expand their product line, regularly releasing new models to accommodate emerging engine designs and configurations. The systems are designed for straightforward installation, typically requiring only basic wiring connections and proper mounting.
The ignition units themselves are compact and lightweight, important considerations when every gram counts in aircraft performance. Despite their small size, they pack serious power, generating high-voltage sparks that ensure complete combustion even in challenging conditions.
Who Should Consider RCEXL Ignition Systems?
These ignition systems are ideal for:
- Giant scale pilots running large displacement petrol engines
- Sport flyers who want reliable ignition for weekend flying
- Scale builders who need compact, reliable ignition for authentic engine installations
- Competition pilots who demand consistent performance
- Anyone looking to upgrade or replace a stock ignition systems for improved reliability
The Bottom Line
At a price point of £53.45 to £58.45, (correct at the time of writing) RCEXL ignition systems represent excellent value for RC pilots who depend on petrol engines. The combination of universal voltage compatibility, multiple configuration options, and proven reliability makes these systems a smart investment for anyone serious about gas-powered RC aircraft.
Whether you’re building a new project or upgrading an existing aircraft, an RCEXL ignition system can provide the spark your engine needs to perform at its best. With options for virtually every engine configuration and plug type, finding the right model for your specific application is straightforward.
The peace of mind that comes from knowing your engine will start reliably and run smoothly flight after flight? That’s priceless.
