The E-flite® Eratix 3D FF (Flat Foamy) 860mm took the market by storm by being the most convenient, easiest to assemble, and fly “flat foamy” model in its class. Now the UMX™ Eratix 3D FF 450mm offers those same benefits in a scaled-down, ultra-micro size so you can fly in more places and smaller spaces – including indoors! It arrives fully factory assembled and ready to fly right out of the box, including a 2S-compatible brushless outrunner motor with a prop saver, four servos, and a Spektrum receiver featuring AS3X® and SAFE® Select technologies.
The E-flite® Eratix 3D FF (Flat Foamy) 450mm offers the aggressive aerobatic plus smooth sport and slow-flying performance of flat foam models – without all the hassles of buying components for and building one! It arrives fully factory assembled and ready to bind to your compatible Spektrum transmitter, allowing you to fly in almost no time. Inspired by the UMX™ Extra 300 and Yak 54 flat foamy models, its laser-cut and composite reinforced airframe makes it light enough to fly extreme 3D maneuvers indoors in spaces no larger than a living or conference room, or almost anywhere outdoors. The factory-installed brushless outrunner motor with a prop saver is compatible with popular 2S 280–350mAh batteries. It's also equipped with expertly tuned AS3X® and SAFE® Select technologies, plus it provides real-time battery voltage and other telemetry information to compatible transmitters. This makes it a versatile addition to the hangar for a wide variety of intermediate to experienced pilots!

Feature Highlights
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 UMX Eratix 3D FF 450mm features 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 to make this the easiest to fly flat foamy model yet!
Telemetry Capable
The UMX Eratix is equipped with a control unit/flight controller that includes an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare equipped transmitters (including the DX6e and 8e, DX6 G2/G3 and 8 G2, the DX9, NX6 to 20, the iX12 to 20, and others) while you fly.
High Performance
The factory-installed brushless power system features a specially tuned outrunner motor with a unique prop saver design. This power system delivers plenty of thrust for unlimited vertical and 3D performance with 2S 280–350mAh batteries!
Uniquely Capable
Like other flat foamy models, the UMX Eratix is capable of slow cruising, smooth sport flying, basic aerobatics, and even aggressive 3D flying — all in the same flight! It offers a truly "mild to wild" flight experience intermediate to experienced pilots will appreciate whether flying indoors in living rooms, garages, and gymnasiums, or outdoors in yards, parks, sports fields, and beyond.
Fully Assembled
The UMX Eratix arrives 100% factory-assembled and ready to fly right out of 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 within minutes of opening the box.
