Scaled down from its world-renowned larger siblings, the E-Flite UMX Viper 531mm EDF Jet brings thrilling ultra-micro ducted fan performance to sports fields and local parks. Constructed from lightweight, composite-reinforced EPS foam, this factory-assembled jet combines aggressive fighter-jet aesthetics with the smooth, forgiving handling of a low-wing sport airplane. At its heart sits a high-performance 30mm electric ducted fan paired with a 4S-compatible brushless outrunner motor, generating incredible top speeds and unlimited vertical punch. Arriving factory-finished in the iconic Aircraft Studio Design trim scheme, it features functional LED navigation and landing lights that enhance orientation during high-speed passes.

Achieving precise control in varying air conditions is effortless thanks to integrated Spektrum AS3X technology, which works behind the scenes to smooth out wind turbulence. For added confidence, optional-use SAFE Select flight envelope protection provides automatic self-levelling along with pitch and bank angle limits at the flip of a switch. The lightweight airframe comes equipped with removable fixed landing gear and a steerable nosewheel for taxiing on paved runways, or can be removed entirely to utilise automatic Hand Launch Assist mode for grass field belly landings. Telemetry-enabled to deliver real-time battery voltage straight to compatible Spektrum transmitters, this Bind-N-Fly model offers an unbeatable jet experience. Just bind your 5+ channel Spektrum DSMX/DSM2 transmitter, install a 4S LiPo flight battery, and take to the skies.

AS3X® and SAFE® Select Technologies for Easier Control

This plane is equipped with exclusive Spektrum™ AS3X® and SAFE® Select technologies. AS3X works seamlessly to smooth out the effects of wind and turbulence, providing a locked-in feel that makes it seem like you're flying a much larger aeroplane. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-levelling that can be turned on and off at the flip of a switch to make it easier to take off, fly, and land!

Bind-N-Fly® Completion Level Advantage

Already own a Spektrum™ transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos, and a Spektrum 2.4GHz receiver installed, so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

Intuitive AirWare™: Simple Setup, Advanced Control

Spektrum™ AirWare™ software offers easy programming for all skill levels. Benefit from automatic wing mixing, in-flight gyro and governor adjustments, and electronic servo travel limits.

Extreme Micro Jet Performance
