Introduction
Thank you for your purchase! This instruction manual will guide you through the installation and operation of your Guardian Stabilization Expander. 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 includes any updates that
were made after your Guardian was purchased. Please read the entire manual carefully before proceeding. If, after you read the manual, you have further questions or
problems, see the “Have Questions or Feedback?” section below.
What the Guardian Does
When used with the Eagle Tree OSD Pro
TM
, the Guardian provides full featured inertial stabilization, and an on-screen Artificial Horizon display. No additional
sensors are required.
The Guardian requires no warm-up period after your model is powered. The Guardian’s advanced features make it easy for you to perform aerobatic maneuvers (if you
are capable!) and immediately return to stabilized flight when desired.
The Guardian is a stabilizer, not a stall-preventer! In some airframes, stalling can create unrecoverable conditions, such as spins, that may result in a crash. Make
sure that you operate your model in a way that avoids stalls.
Intended Uses
The Guardian is intended to be used exclusively for recreational purposes in model planes, boats and cars. Any other use is not supported.
Packing List
Your package should include the following: The Guardian, and a printed version of this manual.
Other Things You Need
To utilize the Guardian, you will need the OSD Pro system with an eLogger V3 or V4. Though stabilization will work without them, a video camera and video
transmitter on your model, and a video receiver and video display on the ground are normally required. Many Eagle Tree FPV dealers sell the required video
equipment. A list of our FPV dealers can be found on our website at
http://www.eagletreesystems.com/OSD/OSD-Pro.htm
.
Steps to Follow
Installation and use of your Guardian should be quite easy and enjoyable if you follow these few steps:
1.
First, if you have not done so already, read through the manuals for your OSD Pro, eLogger, GPS Expander, and any other Eagle Tree sensors, to familiarize
yourself with the connection and function of these devices, and set this equipment up.
2.
Read through this manual to understand the warnings, determine the installation and setup sequence, pre-flight tests, etc., of the Guardian.
3.
If anything is unclear, see the “Have Questions or Feedback?” section below.
4.
Range test and enjoy!
