Assembled in Taiwan
Introduction
Thank you for your purchase! Based on Eagle Tree's proven inertial stabilization technology, the Guardian 2D/3D Stabilizer (the Guardian) stabilizes just about any type of
fixed wing model, and works with any radio. Unlike most “gyro stabilizer” products on the market, the Guardian provides true wing leveling stabilization as well as precise
fly-by-wire control. This lets you configure the Guardian to return to level flight in an emergency, by just flipping a radio switch!
This instruction manual will guide you through the installation and operation of your Guardian. The latest version of this manual is available in the Product Manuals
section of the Support tab on
http://www.eagletreesystems.com
. The online manual is in full color, and includes any updates that were made after this manual was
produced. Please read the entire manual carefully before proceeding. If, after you read the manual, you have further questions or problems, see the “How to Get
Help” section below.
