JMB Aircraft is proud to announce an exciting new partnership with Ultralight Concept. The legendary SV4-RS, a full-scale ULM replica of the iconic Stampe-Vertongen SV-4b, will now fall under the JMB Aircraft banner. It was originally designed in the 1930s as a training aircraft for the Belgian and French air forces and holds a special place in aviation history.
Ultralight Concept has been dedicated to preserving and modernising this classic aircraft. In 2007, the company acquired the original plans of the SV-4b and started an ambitious journey to recreate the aircraft in a 1:1 scale ultralight version. By 2016, the SV4-RS had taken its first flight, combining the timeless elegance of the past with the materials and technology of today.
To comply with LFT-UL (German Airworthiness Rules for Ultralight Aircraft), Ultralight Concept meticulously reduced the empty weight from the original 560 kg to an impressive 295 kg. This weight optimisation, along with the use of modern materials and equipment, allows the SV4-RS to maintain the exact external dimensions of its historic predecessor while meeting contemporary aviation standards.
Since its first flight, around one hundred SV4-RS aircraft have been sold, proving its popularity among aviation enthusiasts and neo-retro aircraft lovers. Now, with JMB Aircraft’s expertise on high-performance aircraft, this remarkable machine will continue to inspire pilots worldwide.
Take a journey through time and rediscover the golden age of aviation. The SV4-RS’s legendary design transports you back to an era of pioneering flight. Its dexterity, stability, and refined craftsmanship ensure an unforgettable flying experience. With its precise, high-end reconstruction, the SV4-RS has become a benchmark for those who appreciate history and performance in one remarkable aircraft.
JMB Aircraft and Ultralight Concept are excited to bring this timeless legend to even more aviation enthusiasts. Stay tuned for more updates as we embark on this incredible journey together.
