Technical Performance
The E-flite 15-25 90-Degree Main Electric Retract Unit represents state-of-the-art electric retraction technology for mid-sized RC aircraft. This precision component operates on standard RC receiver power (typically 4.8–7.4V depending on your receiver and BEC configuration), making it compatible with most modern RC systems used in UK clubs and private flying. The internal electric motor mechanism provides smooth, reliable actuation with consistent cycle times, whether you're retracting gear for a high-speed climb or extending it for a controlled approach to landing. The 90-degree rotating configuration ensures that gear travels smoothly through its arc without binding or jamming, critical for reliable operation during the crucial takeoff and landing phases of flight. The unit's load capacity is specifically rated for the 15-25 size category, meaning it's engineered to handle the weight and shock loads of aircraft in this class whilst maintaining precise positioning and smooth operation. The retract mounting footprint matches other components in E-flite's 15-25 retract system, allowing you to build a complete, integrated landing gear solution using main units, nose units, wire struts and adjustable axles from the same product family. Whether you're installing this unit in a foam composite ARF airframe, a traditional balsa kit build, or a custom scratch-built model, E-flite's engineering ensures trouble-free operation and years of reliable service.

Frequently Asked Questions
- What size aircraft is the 15-25 90-degree retract unit designed for? — This retract unit is specifically engineered for the 15-25 size category of electric RC aircraft. This classification typically encompasses aircraft with wingspans between 1000mm and 1500mm, including mid-sized warbirds, sport trainers, and larger electric aerobatic models. The 15-25 designation ensures that the retract's load capacity, cycle speed and mechanical geometry match these aircraft perfectly.
- How does the 90-degree rotation work? — The 90-degree configuration means the landing gear rotates at a right angle as it retracts, allowing gear legs to fold neatly into wing cavities or fuselage recesses typical of fighter jets and high-performance aircraft. This is distinct from alternative gear designs where gear might retract backwards or at different angles. The 90-degree angle is achieved through the internal mechanical design of the retract unit, which uses a geared motor and linkage system to produce this specific arc of travel.
- What voltage does this retract unit require? — The 15-25 90-Degree Main Electric Retract Unit operates on standard RC receiver power, typically ranging from 4.8V (2-cell NiMH or 1S LiPo) to 7.4V (3-cell NiMH or 2S LiPo). Most modern RC receivers with integrated BECs output in this voltage range, making the retract compatible with virtually any contemporary RC system used by UK modellers. Check your receiver's specifications to confirm BEC voltage output.
- Can I use this retract with any RC aircraft? — No, the 15-25 size classification is crucial for compatibility. This retract is engineered specifically for aircraft in the 15-25 weight and size category. Using it on larger aircraft may cause insufficient load capacity, whilst smaller aircraft may find the retract oversized and heavy. E-flite manufactures retract units across multiple size ranges (10-15, 15-25, 25-46, 60-120) to ensure you select the correctly matched component for your airframe.
- Is this suitable for beginners building their first RC aircraft? — Whilst this retract unit itself is reliable and straightforward to operate, installing retractable landing gear requires more advanced construction skills than fixed gear. Beginners should ensure they have experience with airframe construction, familiarity with servo/motor connections, and understanding of mechanical linkages before tackling a retract installation. If you're new to RC aircraft building, starting with a simpler fixed-gear model is recommended.
- What is the difference between this main retract and a nose retract unit? — The 15-25 90-Degree Main Electric Retract Unit is specifically designed for the main landing gear legs (typically mounted under the wings). A nose retract unit (such as the E-flite EFLG21190) is designed for the front landing gear assembly. Most retractable aircraft use a tricycle configuration with two main gear units and one nose unit. You would typically need one or two of these main units (depending on whether you're building a single-main or dual-main gear configuration) plus a separate nose unit to complete a full retractable landing system.
- Are replacement parts available for this retract unit? — Yes, E-flite provides comprehensive spare parts support for their retract systems. Compatible components in the 15-25 retract family include wire struts (EFLG102), adjustable axles (EFLG104), and nose steering arms (EFLG213), all available through RC Model Shop. This modular approach means you can upgrade, repair or customise your gear setup using genuine E-flite components.
- How does electric retraction compare to servo-based retraction? — Electric retracts like this unit use an integrated electric motor for actuation, offering smoother, quieter operation and simpler receiver integration compared to servo-based systems. Electric retracts also typically provide more consistent cycle timing and require fewer external linkages, reducing weight and complexity. The trade-off is that servo-based systems offer more flexibility for custom installations and fine-tuning.
