Product Information

With a unique delta wing design the UMX™ Ultrix™ was one of the most popular ultra-micro models soon after it was introduced. There was nothing else quite like it around with a wide flight envelope that could go from smooth sport flying, to basic aerobatics, to full on aggressive 3D manouvres all in the same flight. Say hello to its big brother, the E-flite Ultrix 600mm BNF Basic which gives the RC pilot the same awesome flight characteristics except it can now be flown in stronger winds, and, is easier to see.

The Ultrix 600mm comes with an optional use fixed nose wheel for smooth surface take offs and landings and takes 800-850+ 3S LiPo batteries. The power to weight ratio from the twin brushless motors in the Ultrix is phenomenal which means you have unlimited vertical performance as well as hovering capability. Yaw control from the differential thrust gives you advanced aerobatic capabilities which include flat spins, harriers and more. The strengthened and durable lightweight EPP foam airframe comes factory assembled so your E-flite Ultrix 600mm BNF Basic can be airborne in a matter of minutes.


The E-flite Ultrix 600mm BNF Basic is equipped with exclusive AS3X technology that helps the pilot by working behind the scenes making hundreds of small adjustments to help smooth out the effects of wind/turbulence and give you a locked in feel. The other technology on board you Ultrix is the optional-use SAFE Select which allows you to set flight envelope parameters that ensure that if you get into trouble your Ultrix will correct itself until you can regain control. You can be airborne in a matter of minutes after you’ve bound your Ultrix to a Spektrum compatible DSMX/DSM2 equipped transmitter.

If you have a compatible transmitter such as the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6, 8 and 10, the iX12, iX20 and others you can get real time power system related telemetry data. That means you can see how much flight time your battery has left, the amount of current and more. If you want better visibility in the day, or, enjoy some night time flying you can install the optional LED light kit (EFL02205) which is sold seperately. The E-flite Ultrix 600mm BNF Basic is a power packed acrobatic Delta wing king that you’ll love to fly!

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!

Exclusive Technologies

This Ultrix™ is equipped with exclusive Spektrum™ AS3X® and SAFE® Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you're flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-leveling that can be turned on and off at the flip of a switch, making it easy to fly for low-time and experienced pilots alike.

Telemetry Capable

The Ultrix™ is equipped with a control unit/flight controller that includes two ESCs and a Spektrum™ receiver that provides real-time flight battery voltage and other telemetry data to compatible Spektrum AirWare™ equipped transmitters (including the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6, 8 and 10, the iX12, iX20 and others) while you fly.

Uniquely Capable

The unique, innovative design of the Ultrix™ makes it capable of smooth sport flying, basic aerobatics and even aggressive 3D flying — all in the same flight!

Twin Power

Powerful twin brushless motors deliver an incredible power-to-weight ratio to provide the ability to hover plus unlimited vertical performance. Differential thrust offers yaw control and the ability to perform advanced aerobatic maneuvers including harriers, amazing flat spins and more.

High Performance

The factory-installed twin brushless power system delivers excellent speed and unlimited vertical performance, plus longer-than-expected flight times when using the recommended 3S 800–850mAh LiPo batteries with an IC2® connector (or JST connector plus a suitable IC2 to JST adapter, including SPMXCA322, sold separately).

Durable Design

The sleek and simple delta wing design is molded from lightweight yet extremely durable EPP, making the Ultrix™ one of our toughest aircraft ever.

Fully Factory Assembled

The Ultrix™ arrives 100% factory-assembled and is ready to fly within minutes of opening the box. It's equipped with industry-leading Spektrum™ 2.4GHz technology that binds to your 5+ channel DSMX®/DSM2® equipped transmitter so you can be flying in almost no time.

Gear Options

You can use the included fixed nose wheel to taxi, takeoff and land on smooth surfaces. Or you can leave the nose wheel off for more speed and vertical performance plus easy hand launches over and landings on grass.

Optional LED Lights

Install the optional LED light kit (EFL02205) for improved visibility during daylight conditions and to fly in darker conditions or even at night.
