Overview
The E-flite Y-Harness: Dual Plug F-EFLRYH9 is an essential wiring adapter designed for RC enthusiasts who need reliable servo connectivity in their electric-powered aircraft. This dual plug Y-harness is specifically engineered for 10-15 size RC models, making it an ideal choice for builders and pilots maintaining a mid-range fleet of electric RC planes. Whether you're restoring a beloved model or completing a new build, this Y-harness provides the robust connectivity you need to keep your RC aircraft flying reliably.
The Y-harness configuration allows you to split a single servo signal into two parallel connections, which is invaluable when you need to operate multiple control surfaces from a single receiver channel. This is a common requirement in RC aviation, particularly when managing aileron control across both wings or synchronising dual elevator servos. The E-flite brand is renowned throughout the RC hobby community for manufacturing dependable, precision-engineered components, and this Y-harness exemplifies that commitment to quality and reliability.
If you're building or repairing RC aircraft in the UK, finding the right wiring adapters and connectors can be challenging. The E-flite Y-Harness solves this problem by delivering a purpose-built solution that matches the quality standards of your airframe and avionics. RC Model Shop stocks this component as part of our comprehensive range of E-flite replacement parts and spares, ensuring you have access to genuine components when you need them.
Key Features
- Dual Plug Configuration — This Y-harness splits a single servo signal into two parallel connections, allowing you to control two servos simultaneously from one receiver channel, which is essential for coordinated control surface operation in electric RC aircraft.
- 10-15 Size Compatibility — Engineered specifically for RC models in the 10-15 size range, this harness integrates seamlessly with the servo and receiver systems commonly used in this popular aircraft category, ensuring proper electrical matching and physical fit.
- E-flite Quality Engineering — Built to the exacting standards that E-flite is recognised for throughout the RC hobby, this component features reliable solder joints, quality insulation, and durable connectors that will withstand the vibration and temperature variations of powered flight.
- Essential Spare Component — Whether you're troubleshooting a servo control issue or completing a new build from scratch, having the correct Y-harness on hand ensures you can progress with your project without unnecessary delays waiting for parts to arrive.
- Direct Replacement Part — This part carries the official E-flite part number F-EFLRYH9, making it simple to identify and verify compatibility with your specific aircraft model by checking your build manual or parts diagram.
Technical Performance
The E-flite Y-Harness F-EFLRYH9 is a passive wiring harness with no electronic components, meaning it requires no power source and introduces no signal latency or processing delay into your servo control chain. The dual plug design allows both connected servos to receive identical signals from the receiver output, ensuring perfectly synchronised movement—critical when you're controlling surfaces like ailerons or elevators that must move together for stable flight. The harness is constructed with quality copper wire and industry-standard servo connectors, providing low resistance connections that maintain signal integrity from receiver to servo. This is particularly important in RC aviation, where even minor electrical losses can result in sluggish servo response or intermittent control dropout during flight. The 10-15 size specification indicates this harness is optimised for standard servo sizes and receiver voltage ranges typically used in this model category, generally operating at 4.8V to 6.0V with standard lithium polymer or NiMH battery systems. The connectors are polarised to prevent reverse-polarity connection errors, a safety feature that protects your avionics from accidental damage during assembly or maintenance.

Frequently Asked Questions
- What does a Y-harness do in RC aircraft? — A Y-harness allows you to connect two servos to a single receiver channel, causing them to move in perfect synchronisation. This is essential for managing control surfaces that must work together, such as both ailerons on a trainer aircraft or dual elevator servos on a larger model. The Y-harness receives one signal from the receiver and distributes it equally to both servos without any signal processing or delay.
- Is this suitable for beginners building their first RC plane? — Yes, this component is ideal for beginner builders. If your aircraft design requires two servos to operate from one receiver channel—a very common configuration in trainer and sport aircraft—this Y-harness provides a simple, plug-and-play solution. Simply verify your model's documentation matches the 10-15 size specification and you're good to proceed with assembly.
- What aircraft models use this F-EFLRYH9 Y-harness? — This harness is compatible with E-flite electric RC aircraft in the 10-15 size category. Consult your specific model's instruction manual or parts diagram to confirm compatibility, as different models may require different harness types depending on their servo and receiver configuration. RC Model Shop's knowledgeable team can help you identify the correct part if you're unsure.
- Can I use this Y-harness with any receiver brand? — This Y-harness will work with any receiver that uses standard servo connectors, which is virtually all modern RC receivers. However, it's always wise to verify your receiver's output connector type matches the harness connections before ordering. If you have any doubt, our experienced team is happy to confirm compatibility based on your specific receiver model.
- How do I install the Y-harness in my aircraft? — Installation is straightforward: disconnect your servos from the receiver channel you wish to consolidate, plug the single connector end of the Y-harness into the receiver output, then connect each of your servos to the two plug ends of the harness. Ensure all connections are fully seated and secure before powering on your avionics. Always perform a range check and control surface test before flying.
- Is this a passive component or does it require electronics? — The Y-harness is completely passive—it's purely a wiring adapter with no electronics, power requirements, or signal processing involved. This means it introduces no delay, requires no programming, and can never malfunction electrically. It simply divides the signal path between two servos.
