Exclusive Technologies

This Bind-N-Fly Basic model is equipped with exclusive Spektrum AS3X (Artificial Stabilization – 3-aXis) and SAFE® (Sensor Assisted Flight Envelope) 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 the Ultrix™ easy to fly for low-time and experienced pilots alike.

Fully Factory-Assembled

The UMX 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.

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!

This Bind-N-Fly Basic model is equipped with a Spektrum 2.4GHz DSMX receiver featuring AS3X (Artificial Stabilization–3–aXis) technology that works behind the scenes to smooth out the effects of wind and turbulence. The result is a heightened sense of stability and precision that makes you feel like you’re flying a much larger, expertly tuned aircraft.

If this is your first model of its type, or you want an extra margin of safety while familiarizing yourself with the airplane, you can enable the optional-use SAFE® Select flight envelope protection technology built into the receiver. No complex programming is required.

With SAFE Select enabled, you get:

Pitch and Bank Angle Limits
These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.

Automatic Self-Levelling
The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It’s also helpful for keeping the wings level during takeoffs/launches and landings.

Easy Switch Assignment—No Complex Programming Required
The simple procedure for assigning a transmitter switch to turn SAFE Select features on and off doesn’t require any complex programming and takes just a few seconds. For UMX models like this one, SAFE Select is automatically assigned to channel 5 (Gear) so you can turn it on and off with any switch assigned to that channel (switch A by default on most Spektrum computer transmitters).
