The Ultrix

The Ultrix features a unique, all-new design that delivers a flight experience unlike any other, especially for models in the UMX™ (Ultra Micro eXtreme) class. This twin brushless motor-powered, delta-wing airplane excels at smooth sport flying, basic aerobatics and even aggressive 3D — all in the same flight. Its incredible power-to-weight ratio provides hovering capability and unlimited vertical performance. Differential thrust adds yaw control and the ability to perform advanced aerobatic maneuvers including harriers, amazing flat spins and more. Plus EPP construction makes the Ultrix the most durable UMX model yet — ready to thrill RC pilots with more performance in more places and smaller spaces!

Features

  • Innovative and unique design capable of smooth sport, aerobatic AND 3D flying
  • Powerful twin brushless motors deliver the power to hover and climb out vertically
  • Differential thrust for yaw control to perform flat spins and other maneuvers
  • Ultra micro size can be flown in more places and smaller spaces
  • Extremely durable yet lightweight, fully-molded EPP airframe
  • Industry-leading Spektrum™ 2.4GHz DSMX® technology
  • Easy to fly with optional-use SAFE® Select flight envelope protection
  • Unmatched stability and locked-in feel of AS3X® technology for smoother flight performance
  • Optional LED light kit/set (sold separately; EFLU6455) for flying at night
  • Fully factory-assembled and ready to fly

The UMX Ultrix is a smooth handling, extremely versatile delta wing with aerobatic and 3D capabilities that you might not expect based on its looks alone. The twin brushless motors deliver an incredible power to weight ratio that offers good speed, plenty of power to hover and unlimited vertical performance. Differential thrust adds the ability to perform harriers, flat spins and more amazing aerobatics. And extremely durable EPP construction makes this one of the toughest ultra micro models yet. The Ultrix handles windy conditions well, aided by exclusive AS3X® (Artificial Stabilization – 3-aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence for a locked-in feel — it’s like you're flying a much larger airplane. Optional-use SAFE® (Sensor Assisted Flight Envelope) Select technology makes the Ultrix easy enough for low-time pilots to enjoy, and the ultra micro size and lightweight construction are suited for flying almost anywhere. Skilled pilots can cut loose indoors in a space as small as a single basketball court, while large yards, sports fields and RC fields make ideal outdoor flying sites for just about everyone. Fully factory-assembled, the Ultrix is ready to fly within minutes of opening the box. Just add an affordable 1S 500mAh battery (EFLB5001S25) and bind it to a compatible Spektrum™ DSMX®/DSM2® equipped transmitter! You can even install the optional LED light kit (EFLU6455) for improved visibility during daylight conditions and to fly at night!

Man that thing must be super light to have that kind of performance on 1S.

I would liked this to have been a 2s batt plane as it has brushless motors.

She’s whipping that thing around pretty good and it was still over 8 minutes on that small battery. I like it!

yank and bank!!
Cool shape, although the decals are a bit over the top. Performance is very nice.


I guess eflite now has a 1S motor and prop they could upgrade the umx radian with..... maybe a 1000mm brushless radian that falls under the 250g mark.

Ya know .... I might just have to change my mind about this plane; i might could just use one of these for the back yard.

What are the chances this would work with a 2s lipo and how do they manage to sync the motors to prevent yaw?

Now we're talking!

I'd take an upgraded 1S BL UMX Radian over a crazy twin-motor, differential-thrust Ultrix any day.

PS: The electronics and 1S twin-BL powertrain are obviously cool. Hope we get to see them in some toned down and more attractive 1S twin-BL UMX models.
