Key Features
- 9 Gram Sub-Micro Size — At just 9 grams, this servo is exceptionally lightweight, making it perfect for micro and ultra-light RC aircraft where every gram of weight matters. Reducing servo weight directly translates to improved flight performance, better handling, and extended flight times on your RC model.
- Metal Gear Construction — The metal gear design ensures durability and longevity, providing superior strength compared to plastic gears. Metal gears resist wear and can handle the demands of frequent use, making this servo a dependable choice for serious RC enthusiasts who want equipment that will last.
- Reverse Rotation Configuration — This reverse servo allows for flexible mounting and control options, eliminating the need for complex linkage workarounds in your RC build. The reverse configuration is particularly valuable when space is limited or when your RC model's design benefits from reversed control inputs.
- Universal Connector — The universal connector design ensures compatibility with most RC receivers and control systems, making this servo a versatile addition to your RC toolkit. Whether you're building a new RC model or upgrading an existing one, the universal connector simplifies integration.
- Analog Servo Technology — This analog servo offers straightforward, reliable operation without requiring programming or complex setup procedures. For RC enthusiasts who prefer simplicity and dependability, the analog design eliminates unnecessary complexity while delivering consistent performance.
- Extended Wire Length — The 450mm (17.71 inch) wire length provides excellent flexibility in servo placement within your RC airframe or model. This generous wire length means you can position the servo where it works best for your design without worrying about reaching the receiver or control system.

Frequently Asked Questions
- What is a reverse servo and why would I need one? — A reverse servo rotates in the opposite direction to a standard servo. This is invaluable when your RC model's design or space constraints mean you cannot use a standard servo in a particular location. Rather than requiring complex mechanical solutions or additional linkage, a reverse servo integrates directly into your RC build, simplifying construction and improving reliability.
- How much does this servo weigh and why is that important? — At just 9 grams, this sub-micro servo is exceptionally lightweight. For RC aircraft and micro RC models, servo weight directly impacts performance. Every gram you save on servos translates to better flight characteristics, improved responsiveness, and longer flight times on your RC plane or helicopter.
- What are the dimensions and will this fit my RC model? — The servo measures 12mm in length, 20mm in width, and 23mm in height, making it one of the smallest available servos. These compact dimensions make it suitable for micro RC aircraft, compact RC helicopters, and other space-constrained RC applications. The 450mm wire length provides flexibility in servo placement within your airframe.
- Is this servo programmable? — No, this is an analog servo without programmable features. This keeps the servo simple, reliable, and easy to use. If you require programmable servo functionality for your RC project, you may want to consider digital servo alternatives, though they will be heavier and larger.
- What type of connector does this servo use? — This servo features a universal connector that is compatible with most RC receivers and control systems commonly used in the UK RC market. The universal design ensures you can integrate this servo into most RC builds without requiring adapters or modifications.
- What is the wire length and can I extend it? — The servo includes a 450mm (17.71 inch) wire lead as standard, which is a substantial length for a sub-micro servo. This length allows flexible servo placement within compact RC models. If you require additional length, servo extension leads are readily available from RC retailers.
- Is the metal gear construction worth the extra cost? — Yes. Metal gears are significantly more durable than plastic gears, resisting wear and lasting much longer with regular use. For serious RC builders and pilots who use their equipment frequently, metal gear servos provide better long-term value despite higher initial cost. The durability ensures your RC investment continues performing reliably season after season.
