E-FLITE UMX Eratix 3D FF

Radio-Controlled Planes for RC Pilots

Overview

The E-flite® UMX™ Eratix 3D FF 450mm brings the convenience and performance of the larger Eratix 3D FF into an ultra-micro format that can be flown almost anywhere—including indoors. Designed to be the most accessible flat-foamy in its class, it arrives fully factory assembled and ready to fly, so there’s no building or component sourcing required.

Its lightweight, laser-cut airframe with composite reinforcement delivers aggressive 3D capability along with smooth sport and slow-flight performance. Inspired by popular UMX flat-foamy designs, the Eratix 3D FF 450mm is light enough for extreme 3D maneuvers in small indoor spaces, yet capable outdoors in calm conditions. The model comes equipped with a 2S-compatible brushless outrunner motor with prop saver, four servos, and a Spektrum receiver featuring AS3X® and SAFE® Select technologies for stability and confidence. Real-time telemetry, including battery voltage, is also supported with compatible transmitters—making this a versatile, ready-to-fly option for intermediate to experienced pilots.
