More Information

The E-flite Eratix 3D FF 860mm quickly became popular as one of the most convenient and easy to assemble flat foamy models in its class. The UMX Eratix 3D FF 450mm brings those same benefits in a smaller ultra micro size, making it possible to fly in more places and smaller spaces, including indoors. It arrives fully factory assembled and ready to fly, featuring a 2S compatible brushless outrunner motor with a prop saver, four servos, and a Spektrum receiver equipped with AS3X and optional SAFE Select technologies.

The UMX Eratix 3D FF 450mm delivers the aggressive aerobatic performance and smooth slow flying characteristics typical of flat foam models, without the need to source and assemble components. It is ready to bind to a compatible Spektrum transmitter, allowing you to be airborne within minutes. Inspired by models such as the UMX Extra 300 and Yak 54, the laser cut and composite reinforced airframe is lightweight yet strong enough for demanding 3D manoeuvres.

Its ultra micro size makes it ideal for flying indoors in spaces such as living rooms or halls, while still being capable outdoors in calm conditions. The factory installed brushless power system supports common 2S 280–350mAh batteries, providing strong performance across a wide flight envelope.

With expertly tuned AS3X for stability and optional SAFE Select for added control, along with real time battery voltage and telemetry feedback to compatible transmitters, the UMX Eratix 3D FF 450mm is a versatile option suited to intermediate and experienced pilots looking for a compact 3D capable model.
