More Information
Featuring functional lights, a 4S compatible power system, and more, the E-flite UMX (Ultra Micro eXtreme) Viper 30 mm EDF is scaled down from the best-selling 64 mm, 70 mm, and 90 mm models to deliver smooth handling plus incredible performance that makes it the class-leading choice for first-time to experienced EDF pilots! Like the full-scale ViperJet, it sports fighter-jet looks with the stability of a low-wing sport aeroplane, so more pilots can enjoy flying a jet – even if it’s your first-ever EDF! Plus, its exclusive AS3X and SAFE Select technologies make it easier to hand-launch or take off and land than other similar class models.
Similar to the full-scale ViperJet, the E-flite UMX Viper 30 mm EDF delivers fighter-jet looks and performance with low-wing prop-driven aeroplane handling so more pilots can enjoy flying a jet! It’s a scale EDF that flies smoothly and handles like a sport aeroplane – yet is also capable of incredible top speeds and aerobatics. But what truly sets it apart is how easy it is to hand-launch or take off, fly, and land, which makes it the class-leading choice for a wide variety of pilots. The lightweight, composite-reinforced airframe arrives factory assembled and nearly ready to fly right out of the box, plus it’s factory-finished in the now iconic Aircraft Studio Design trim scheme. A 4S-compatible power system delivers modern-day EDF performance to make it the highest-performance ultra-micro class jet model yet! It’s also equipped with expertly tuned AS3X and optional-use SAFE Select technologies, plus it provides real-time battery voltage and other telemetry information to compatible transmitters. Its ultra-micro size makes it possible to fly in more places and smaller spaces than most other EDF models, including at many large parks and sports fields. The fixed landing gear with a steerable nose wheel makes it easy to taxi, take off from, and land on smooth surfaces. Or you can quickly remove the landing gear for increased speed and vertical performance, including easy hand launches with automatic Hand Launch Assist mode and smooth landings on grass. It all adds up to deliver an affordable and convenient high-performance EDF flying experience you simply can’t get with any other model!
