Horizontal stabilisers are critical components in any RC aircraft, as they provide pitch control and maintain the aircraft's longitudinal stability during flight. A quality stabiliser like this one can make the difference between smooth, predictable flight characteristics and unstable, difficult-to-control behaviour. The FMS ROC HOBBY VIPER stabiliser has been designed with both performance and reliability in mind, making it an excellent choice for pilots looking to maintain their aircraft in top condition or for those building their first aircraft and wanting quality components from the outset. Available from RC Model Shop, your trusted UK RC retailer, this part represents genuine FMS quality at an accessible price point.

This horizontal stabiliser is ideal for RC aircraft enthusiasts of all skill levels. If you own an FMS 70MM Super Viper or a compatible aircraft platform, having a spare or replacement stabiliser on hand is sensible maintenance planning. It's also perfect for those looking to upgrade their aircraft with OEM components from the original manufacturer. With FMS's reputation for quality engineering and attention to detail, you can be confident that this component will perform consistently and reliably, giving you the confidence to push your RC flying skills further.

Key Features

• 70MM Compatible Design — This horizontal stabiliser is purpose-built for 70mm aircraft platforms, ensuring a perfect fit and optimal aerodynamic performance with your FMS Super Viper or compatible models. The 70mm specification refers to the ducted fan diameter, which is the standard size for mid-range electric RC aircraft that balance speed, manoeuvrability and flight time effectively.
• FMS OEM Quality — Manufactured by FMS (Freewing Model Store), a recognised leader in RC aircraft design and production, this component meets the exacting quality standards you'd expect from the original equipment manufacturer. Using genuine FMS parts ensures compatibility and performance consistency with your aircraft.
• Precision Construction — The stabiliser has been engineered with precision tolerances to ensure smooth, predictable pitch control throughout your flight envelope. Quality construction materials and careful manufacturing mean your aircraft will maintain stable flight characteristics in various wind conditions and flight regimes.
• Enhanced Flight Stability — A properly functioning horizontal stabiliser is absolutely essential for maintaining longitudinal stability during flight. This component ensures your aircraft responds predictably to control inputs and maintains level flight when the elevator is neutral, reducing pilot workload and improving the overall flying experience.
• Replacement and Upgrade Capability — Whether you need to replace a damaged stabiliser or upgrade an existing aircraft, this component provides a straightforward path to improved performance. It's a bolt-on replacement that requires no complex modifications or adjustments to your airframe.
• Competitive Price Point — At just £14.99 GBP (approximately $14.99 USD), this OEM-quality component represents exceptional value for serious RC aircraft pilots and hobbyists who demand reliability without excessive cost.

Technical Performance

The FMS ROC HOBBY VIPER 70MM HORIZONTAL STABILIZER represents the culmination of modern RC aircraft design principles. At 70mm, this stabiliser is optimised for electric-powered aircraft in the mid-range performance category, where it provides the perfect balance between control authority and aerodynamic efficiency. The component has been manufactured using quality materials selected for their durability and aerodynamic properties. FMS aircraft are known throughout the RC community for their excellent flight characteristics, and a significant portion of that success comes from precisely engineered control surfaces like this horizontal stabiliser. The stabiliser's design ensures minimal deflection under normal flight loads whilst still providing the control authority needed for responsive pitch control. This is critical for safe, enjoyable RC aircraft operation. Whether you're flying in calm conditions or dealing with modest wind, this stabiliser will maintain the stability characteristics you expect from a quality FMS aircraft. The engineering philosophy behind FMS aircraft emphasises building reliable, forgiving platforms that allow pilots to focus on enjoying the hobby rather than fighting unstable flight characteristics. This horizontal stabiliser embodies that philosophy, delivering straightforward, dependable performance flight after flight.

Frequently Asked Questions

• What is a horizontal stabiliser and why does it matter for RC aircraft? — A horizontal stabiliser (also called an elevator or tailplane) is the small wing-like surface at the rear of an aircraft that controls pitch (nose up and nose down movement). It's absolutely essential for stable flight. Without a properly functioning stabiliser, your aircraft would be nearly impossible to control. The stabiliser provides both static stability (the aircraft's natural tendency to return to level flight) and control authority so you can command the aircraft to climb or descend as needed. A quality stabiliser like this one ensures smooth, responsive control and stable flight characteristics throughout your flight session.
• Is this a replacement part or an upgrade component? — The FMS ROC HOBBY VIPER 70MM Horizontal Stabiliser functions as both. It can serve as a direct replacement if your existing stabiliser has been damaged or worn, restoring your aircraft to like-new condition. It also works as an upgrade component if you're replacing older or lower-quality stabilisers with genuine FMS OEM equipment. Either way, you're getting a quality component that FMS engineers designed specifically for 70mm aircraft platforms.
• How do I know if this will fit my aircraft? — This stabiliser is designed for 70mm electric RC aircraft, particularly FMS models in their Super Viper lineup. If your aircraft has a 70mm ducted fan motor and is an FMS product, this will be compatible. If you own a different brand of 70mm aircraft, compatibility may vary, so it's worth checking with the manufacturer or contacting RC Model Shop for guidance before purchasing. We're here to help ensure you get the right component for your specific aircraft.
• What makes FMS components different from generic alternatives? — FMS (Freewing Model Store) is the original manufacturer of FMS aircraft and components, meaning they design and engineer every aspect of their products for optimal performance and compatibility. When you buy genuine FMS parts like this stabiliser, you're getting components engineered specifically for FMS aircraft using the same quality standards and materials FMS uses during initial manufacture. This consistency in quality and design means your aircraft will perform exactly as the designers intended. Generic alternatives from unknown manufacturers may fit superficially but could have tolerances or materials that compromise flight performance or longevity. Genuine FMS parts give you confidence and reliability.
• Is this suitable for beginners to RC aircraft? — Absolutely. If you've purchased an FMS 70MM electric RC aircraft as a beginner, this stabiliser (whether as a replacement or spare) is an excellent choice. FMS aircraft are renowned for being beginner-friendly with stable, forgiving flight characteristics. This stabiliser is a key component in delivering that beginner-friendly performance. Having a spare on hand is wise planning, as it means you can continue flying even if your original stabiliser suffers damage. This lets you focus on improving your piloting skills rather than worrying about equipment problems.
• Do I need any special tools to install this stabiliser? — Installation is straightforward and requires only basic hand tools like a screwdriver. The stabiliser mounts via simple fasteners to the fuselage, similar to how any RC aircraft control surface attaches. The exact installation process will be covered in your aircraft's manual or in the instructions provided with this component. If you've ever worked on any RC aircraft before, you'll find this installation routine and simple. RC Model Shop can also provide guidance if you have specific questions about installation.
• What is the warranty and return policy? — FMS provides a 90-day warranty on electronic accessories and a 30-day return policy for new and unused products purchased directly. This component, as a mechanical part, is covered under FMS's quality assurance standards. RC Model Shop stands behind all products we sell, and if you receive this item damaged or defective, we'll work with you to resolve the issue quickly and fairly.
