FMSEM104

Overview

The FMS 70MM VIPER 15th Anniversary Horizontal Stabilizer (FMSEM104) is a precision replacement component engineered for FMS Viper aircraft models. This horizontal stabiliser represents FMS's commitment to delivering authentic, high-quality RC aeroplane parts that maintain the structural integrity and flight characteristics of their aircraft range. Whether you are an experienced RC aircraft enthusiast flying scale warbirds, a weekend hobbyist maintaining your fleet, or someone expanding their collection of RC aeroplanes in the UK, having genuine replacement parts on hand ensures your aircraft remains in peak condition and ready for flight.

FMS has built a reputation for manufacturing reliable RC aircraft that combine realistic scale detail with genuine flying performance. The 70MM VIPER airframe has earned respect amongst RC flyers for its balanced handling characteristics, robust construction, and impressive scale appearance. As with all high-performance RC aircraft, wear and tear during flight operations, accidents, or transport can occasionally necessitate replacement of key structural components. The horizontal stabiliser is a critical control surface that governs pitch control and maintains longitudinal stability throughout all phases of flight—from gentle cruising to aggressive aerobatic manoeuvres.

This 15th Anniversary edition horizontal stabiliser demonstrates FMS's ongoing dedication to supporting their aircraft across multiple generations. By offering genuine factory replacement parts, FMS ensures that your investment in their RC aircraft continues to deliver excellent performance and reliability season after season. Whether you need a replacement due to damage, want to maintain spare parts for regular flying, or are undertaking a complete restoration of a Viper airframe, this stabiliser provides the precise fit and engineering quality you expect from an authorised RC aircraft manufacturer.

Key Features

Technical Performance

The FMS 70MM VIPER Horizontal Stabiliser is engineered as a precision aerodynamic control surface that plays a fundamental role in maintaining longitudinal stability and pitch control authority throughout the flight envelope. The horizontal stabiliser works in conjunction with the elevator control surface to allow the pilot to manage the aircraft's attitude and pitch rate through direct control input from the radio transmitter. This component is specifically dimensioned and balanced for the 70MM VIPER airframe, which features a 70-millimetre diameter turbine or motor configuration that characterises this particular aircraft model series. The stabiliser's aerodynamic profile, chord length, and span are calculated to provide appropriate static and dynamic stability margins, preventing the aircraft from becoming either too sensitive to control inputs or sluggish in responding to pilot commands. Built using FMS's proven construction methods with durable composite and foam materials, the stabiliser can withstand the stresses imposed during high-speed flight, aggressive aerobatic manoeuvres, and rough field operations typical of UK RC flying environments. Whether flying at local RC clubs, at designated flying sites, or during competitive events, this stabiliser maintains its structural integrity and aerodynamic performance. The component represents genuine factory engineering rather than aftermarket approximation, meaning every dimension and material specification aligns with FMS's original design intent for the 15th Anniversary Viper model. For RC aircraft enthusiasts in the UK seeking reliable replacement parts that restore their aircraft to factory condition, this horizontal stabiliser delivers the precision engineering expected from an authorised FMS supplier.
