E-flite UMX™ Eratix 3D Flat Foamy BNF Basic Electric Airplane (450mm) w/AS3X® & SAFE® Select - EFLU02050

Micro Aircraft with 3D Aerobatic Capability

The E-flite® UMX™ Eratix 3D Flat Foamy BNF Basic Electric Airplane combines compact size, precision engineering, and powerful performance for an unmatched ultra-micro flying experience. Scaled down from the popular Eratix 3D FF 860mm, this 450mm version delivers the same exceptional flat foamy (FF) aerobatic and sport-flying capabilities in smaller spaces. Arriving 100% factory assembled, it's designed for intermediate to experienced pilots who want to enjoy smooth, stable, and agile 3D flight almost anywhere.

About the UMX Eratix Airplane

Innovative Design

The UMX Eratix features a laser-cut, composite-reinforced flat foam airframe that balances lightweight agility with impressive durability. Oversized control surfaces and a streamlined structure provide exceptional 3D maneuverability, from hovering to rolling circles. Its portability and no-hassle setup mean you can enjoy top-tier aerobatic performance in nearly any location without the complexity of larger builds or extensive assembly time.

Advanced Electronics & Power System

This airplane is equipped with a powerful 2S-compatible brushless outrunner motor featuring a prop saver, delivering abundant thrust for unlimited vertical and precise 3D control. The integrated control unit includes an ESC and a Spektrum™ receiver with 2.4GHz DSMX® technology and real-time battery telemetry, while four factory-installed servos provide confident control. Together, these electronics ensure smooth, responsive handling and reliable performance during every flight session.

Smart Technology & Control

Exclusive Spektrum AS3X® technology works behind the scenes to counteract wind and turbulence, giving the UMX Eratix a locked-in, larger-airplane feel. Optional SAFE® Select technology adds flight envelope protection, including automatic self-leveling and pitch angle limits, which can be activated or deactivated with a switch. These features make the aircraft adaptable for both learning maneuvers and pushing the limits of advanced 3D flight.
