Overview

The UMX™ Ultrix™ is a smooth handling, very versatile delta wing with aerobatic and 3D abilities that you might not expect based on its looks alone. The twin brushless motors provide an extraordinary power to weight ratio that uses excellent speed, lots of power to hover and limitless vertical performance. Differential thrust adds the capability to carry out harriers, flat spins and more fantastic aerobatics. And very durable EPP building and construction makes this one of the most difficult ultra micro designs yet. The Ultrix manages windy conditions well, assisted by exclusive AS3X® (Synthetic Stabilization – 3-aXis) innovation that works behind the scenes to smooth out the results of wind and turbulence for a locked-in feel — it resembles you're flying a much larger plane. Optional-use SAFE® (Sensor Assisted Flight Envelope) Select innovation makes the Ultrix easy enough for low-time pilots to enjoy, and the ultra micro size and lightweight building and construction are matched for flying nearly anywhere. Skilled pilots can cut loose inside your home in a space as little as a single basketball court, while large backyards, sports fields and RC fields make ideal outside flying sites for practically everybody. Completely factory-assembled, the Ultrix is all set to fly within minutes of opening package. Simply include an affordable ONE 500mAh battery (EFLB5001S25) and bind it to a compatible Spektrum™ DSMX®/DSM2® equipped transmitter!

Rated 5 stars Best Micro Ever
By Loophole L on March 18, 2020   Verified Purchase

Spectacular micro ! Handles wind nicely; does flat spins on Stability mode, and "bullet dives" on Stunt two mode. Flies easily, lands gracefully. You can't go wrong with this fun bird !
