E-flite UMX Eratix 3D FF 450mm BNF-Basic – Ready-to-Fly Micro RC Plane

Overview

The E-flite UMX Eratix 3D FF 450mm is a compact, ultra-micro version of the popular Eratix 3D FF. It’s designed to fit in tighter spaces while delivering engaging aerobatic potential. This BNF-Basic edition means the model arrives factory-assembled and ready to fly with your own transmitter, battery, and charger to complete the setup.

Compact, scalable design

With a scaled-down form factor derived from the 860mm version, the 450mm Eratix opens up flight in smaller rooms, parks, and clutter-free outdoor areas. Its foam construction contributes to a light, responsive feel that rewards precise control, even for pilots transitioning from larger aircraft.

• Scaled-down, ultra-micro version of the Eratix 3D FF (Flat Foamy) 860mm for more places to fly
• Durable foam body with crisp edges and smooth surface for confident handling

Power and protection

The model is powered by a 2S-compatible brushless outrunner motor with a prop saver, delivering steady, lively performance suitable for practicing basic 3D-style maneuvers and precision hovering. The prop saver helps reduce wear during casual, hands-on flights and occasional bumps.

• Powerful 2S brushless outrunner motor with prop saver
• Responsive throttle and quick response for short-field flying

Telemetry and flight stability

A Spektrum receiver provides fly-by telemetry and industry-leading 2.4GHz DSMX technology, offering real-time feedback on signal strength and range. This helps you stay aware of the link quality as you explore different flight conditions.

• Spektrum receiver with fly-by telemetry and DSMX 2.4GHz
• Real-time data helps you gauge range and connection during flights

Flight safety and ease of use

Easier handling is supported by SAFE Select flight envelope protection as an optional feature, which helps maintain confidence during experimenting with new maneuvers or transitions. The model is fully factory-assembled, so it’s ready to fly once you add your own transmitter and power kit.

• Optional SAFE Select flight envelope protection for easier first flights
• Factory-assembled and ready to fly out of the box

What you’ll need

As a BNF-Basic model, you’ll supply a compatible transmitter, battery, and charger. This keeps the kit flexible to suit your preferred gear while preserving the compact, park-friendly nature of the Eratix 3D FF 450mm.

• Transmitter required (not included)
• Battery and charger not included
• Compatible power kit to complete the BNF package

In short, the E-flite UMX Eratix 3D FF 450mm offers a compact, responsive flying experience with useful telemetry, protective flight modes, and straightforward assembly — all designed to help you explore micro aerobatics in real-world spaces without sacrificing the sense of scale that makes model aviation so rewarding.
