RCEXL Ignition systems for RC planes

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. Get in touch to find out more about the options and what would suit your engine.

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.

Why Carbon Fibre Undercarriage for RC Planes!

Unbreakable Performance: The Definitive Guide to Full Carbon Fibre RC Plane Undercarriages

You’ve probably felt that sinking feeling when your RC plane hits a bump on landing. The gear bends or snaps, and suddenly you’re out of the sky for weeks searching for a replacement. That weak spot in your setup kills the fun fast.

Most RC pilots stick with basic aluminum or steel landing gear supplied by the manufacturer. These metals hold up okay for casual flights, but they add extra weight and wear out under real stress. You end up with cracks or permanent weakness after a few rough landing, some aren’t even up to the ob out of the factory.

Full carbon fiber RC plane undercarriages change the game. They pack insane strength into a lighter component. This upgrade boosts your keeps you flying longer without breakdowns. Serious flyers swear by them for good reason.

Superior Strength and Impact Resistance

Carbon fiber undercarriages take hits that would trash metal gear. They bend and spring back, so you can push your plane harder.

Unmatched Tensile Strength Compared to Aluminum

Carbon fiber, or CFRP, has a tight weave of carbon threads in resin. This setup lets it handle huge pulls and pushes. Aluminum alloys like 6061-T6 max out at about 40,000 psi in tension. Carbon fiber layups often hit 500,000 psi or more. That’s over ten times tougher.

In RC planes, this means your gear won’t bend on a bad landing.

Tests from aerospace labs show carbon fiber resists dents better too. For your RC hobby, that translates to gear that lasts through seasons of abuse.

Landing Gear Longevity and Fatigue Reduction

Hard landings build up tiny stresses in metal over time. They lead to cracks you can’t see until it’s too late. Carbon fiber flexes a bit, like a tough spring, and snaps back to shape.

This memory effect cuts down on wear. Your undercarriage won’t weaken after 100 rough touches. Instead, it holds strong, ready for the next flight.

To check for issues, look for small splits in the surface. Unlike metal, where you hunt for hidden fatigue, carbon fiber shows damage right away. Tap it lightly—if it sounds dull, inspect closer. Clean with mild soap, and avoid harsh chemicals that might eat the resin.

Real-World Stress Testing Scenarios

Grass fields hide roots and holes that test any gear. Carbon fiber shines here, soaking up jolts without permanent bends. Gravel runways pound metal parts loose, but CF stays strong.

Our Full Carbon Fibre undercarriages flex with the bumps but are way stronger than those that are made from fibreglass and a carbon skin. this allows them to be thinner but stronger.

Switch to CF, and you’ll notice the difference on your local field. It handles real bumps better than stock parts ever could.

Significant Weight Reduction for Enhanced Aerodynamics

Extra weight on your plane drags down speed and climb. Full carbon fiber RC plane undercarriages provide higher strength to weight ratio than aluminum parts.

Calculating the Advantage: Weight Savings Analysis

A standard aluminum gear for a 50-inch wingspan plane weighs around 4 ounces. Swap to carbon fiber, and it drops to 1.5 ounces. That’s a 60% cut for that part alone.

For a mid-size model, total weight might fall 2-3%. On a 5-pound plane, you save a little but gain so much in strength. Small change, big payoff in the sky.

Larger models see even more gains. A 10-pound setup could lose even more.

Improved Power-to-Weight Ratio

Lighter gear frees up power for climbs, and slimmer undercarriage means less drag. Adding our sectioned, not flat fronted profile means less drag. it may not seem much but it all adds up.

Wing loading drops, so stalls happen later. You get more hang time in glides. For power-hungry setups, this boost turns good flights into great ones.

Vibration Damping and Operational Noise Reduction

Rough ground sends shakes through your plane. Metal gear rattles everything loose. Carbon fiber quiets it down and protects your build.

Natural Vibration Absorption Properties

Carbon fiber is strong, but flexible, and soaks up vibes like a sponge. Metals ring like bells on bumps, passing shakes to servos and batteries. CF stops that chain.

Smoother Taxiing and Ground Handling

Taxi on uneven turf with metal, and it jerks like a cart. Carbon fiber can dampen those hits for smoother taxiing.

Maintenance and Corrosion Resistance Advantages

Wet fields or salt air eat metal gear. Carbon fiber laughs it off, so you spend less time fixing.

Immunity to Environmental Degradation

Steel rusts fast in damp spots. Aluminum needs paint or it pits. Carbon fiber ignores water, salt, and sun—no coatings required.

After a session, just wipe it down. No worries about hidden rot. Your gear still looks new .

Ease of Repair and Inspection

Damage on CF shows as white lines or soft spots. No digging for cracks like in aluminum. A quick once-over tells you if it’s good.

Repairs use epoxy patches for small dings. Pros handle big fixes, but breaks are rare. Metal often needs full swaps.

Keep it clean with a soft cloth and wax for UV block. Avoid abrasives that scratch the shine.

Long-Term Cost Efficiency

Up front, CF sometimes costs a little more than aluminum. But it lasts much longer. Fewer replacements mean real savings.

Downtime drops too. No waiting for parts when gear holds up.

Conclusion: The Definitive Upgrade for Performance RC Aircraft

Full carbon fiber RC plane undercarriages blend top strength, low weight, and tough build. They cut vibes, ease upkeep, and boost every flight.

No more weak links holding you back. For high-energy models, this gear is essential. It turns risky runs into reliable fun.

Weigh your needs against the price. If you chase peaks in speed and skill, make the switch. Your next landing will thank you.
