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.
This model is equipped with Horizon Hobby and Spektrum exclusive AS3X (Artificial Stabilization – 3-aXis) and optional-use SAFE (Sensor Assisted Flight Envelope) Select technologies, and when SAFE Select is turned on using the mode switch (B on the Spektrum InterLink DX controller) it offers:
Pitch and Bank Angle Limits: These envelope limits keep the airplane from rolling or pitching upside down. They also prevent excessive climb or dive angles.
Automatic Self-Leveling: The airplane instantly returns to and holds level flight when the sticks are released and in the center position. It’s also helpful for keeping the wings level during takeoffs and landings.
