E-flite Viper 30mm RC Jet Introduction
Featuring functional lights, a 4S compatible power system, and more, the E-flite® UMXT (Ultra Micro eXtreme) Viper 30mm EDF is scaled down from the best-selling 64mm, 70mm, and 90mm 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 airplane, 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.
Overview
Similar to the full-scale ViperJet, the E-flite® UMXT Viper 30mm EDF delivers fighter-jet looks and performance with low-wing prop-driven airplane handling so more pilots can enjoy flying a jet! It’s a scale EDF that flies smoothly and handles like a sport airplane - 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 nosewheel 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!

Technical Performance
The E-flite UMX Viper 30mm EDF jet is engineered for serious performance within the ultra-micro category. The 30mm fan is powered by a Spektrum brushless outrunner motor that is fully compatible with 4S LiPo batteries (14.8V nominal), delivering significantly higher performance than 3S alternatives. The integrated Spektrum brushless ESC is factory-installed and precisely configured for this motor and power system combination. The aircraft weighs just 125 grams, making it one of the lightest high-performance EDF jets available and perfect for flying in confined spaces including parks and smaller flying fields. With a wingspan of 531mm and length of 460mm, the UMX Viper represents the pinnacle of compact jet design. The airframe utilises composite-reinforced EPS construction, which provides an excellent balance between lightweight design and structural durability whilst remaining repairable using standard foam-safe adhesives. The power system delivers the highest performance of any single-motor powered ultra-micro class jet available, providing impressive top-end speed capabilities and rapid acceleration that rivals much larger models. The expertly tuned AS3X stabilisation system continuously adjusts control inputs to maintain stable flight through wind and turbulence, whilst SAFE Select provides optional flight envelope protection with bank and pitch angle limiting plus automatic self-levelling. The four factory-installed Spektrum linear servos provide precise, responsive control across all flight axes. The Spektrum control unit incorporates both the receiver and brushless ESC in a single compact unit, reducing weight and complexity whilst maintaining full functionality. Battery compatibility is specifically 4S 14.8V LiPo batteries with IC2 connectors; a 450mAh 30+C capacity battery is required for optimal performance and flight duration. The integrated telemetry system communicates with compatible Spektrum transmitters to provide real-time battery voltage monitoring and other flight data during flight.

Frequently Asked Questions
- Is the E-flite UMX Viper 30mm EDF suitable for beginner RC pilots? — This aircraft is classified as Skill Level 2, meaning it requires some prior RC flying experience. You should have successfully flown other high-performance ultra-micro models, larger sport aeroplanes like the E-flite T-28 Trojan 1.1m or Valiant 1.3m, various Timber 1.5m models, or other EDF jets like the E-flite Habu SS 50mm or 70mm before attempting to fly the UMX Viper 30mm EDF. However, the inclusion of AS3X stabilisation and optional SAFE Select flight envelope protection does make it significantly easier to fly than comparable EDF jets without these technologies.
- What battery does the UMX Viper 30mm EDF require? — This aircraft requires a 4S LiPo battery with 14.8V nominal voltage and IC2 connector type. A 450mAh 30+C capacity battery is recommended for optimal performance and flight duration. You will also need a compatible LiPo charger; Spektrum smart chargers such as the S100 or S200 are ideal choices.
- What transmitter do I need to fly the UMX Viper 30mm EDF? — Any full-range 5+ channel Spektrum DSMX or DSM2 compatible transmitter will work. For access to real-time telemetry features including battery voltage monitoring, you should choose a Spektrum AirWare-equipped transmitter such as the DX6e, DX8e, DX6 G2/G3, DX8 G2, DX9, NX6 to NX20, or iX12 to iX20 series.
- Can the landing gear be removed from the UMX Viper? — Yes, the fixed landing gear with steerable nose wheel can be easily removed, which increases top speed and vertical performance whilst enabling automatic Hand Launch Assist mode for grass-field operation and easy hand launches without the weight penalty of the gear.
- What is the difference between this model and the larger Viper jets? — The UMX Viper 30mm is a true scaled-down version of the extremely popular 64mm, 70mm, and 90mm Viper models. It delivers comparable handling characteristics and jet-like performance in a package that is significantly smaller, lighter, more affordable, and capable of flying in more locations including smaller parks and sports fields. The 30mm EDF power system is the highest performance available in the ultra-micro class, delivering impressive top speed and aerobatic capability whilst remaining compact and lightweight.
- Is the UMX Viper 30mm EDF registered with the FAA or require Remote ID? — No, at just 125 grams this aircraft is under the 250-gram weight limit and therefore requires no FAA registration or Remote ID in the UK, making it accessible for flying at more locations including many large public parks and recreational spaces.
- How difficult is assembly? — Assembly is minimal as the aircraft arrives factory-assembled. You simply need to install the one-piece wing using the quarter-turn thumbscrew and hands-free connections, install a fully charged 4S LiPo battery, bind the receiver to your compatible Spektrum transmitter, and you're ready to fly.
- What makes the UMX Viper easier to fly than other EDF jets? — Three key technologies make this jet more accessible: exclusive AS3X stabilisation works continuously to smooth out wind effects and turbulence, providing a locked-in feel; optional-use SAFE Select offers pitch and bank angle limits plus automatic self-levelling via a switch; and automatic Hand Launch Assist mode makes grass-field operation and hand launches significantly easier than comparable models.
