Attached is a Tutorial on ex-mixers in FrSky's operating system for the Horus transmitter line. It includes an overview of the structure of an ex-mixer and uses examples to illustrate how the various features work. It also touches on the use of flight modes and curves, although those are not directly addressed.

For me the ex-mixer section in FrOS was the least intuitive and most confusing section. I decided that writing a tutorial for others was the best way for me to learn it and indeed writing the Tutorial has forced me to work my way through it. Hopefully this tutorial will save others at least some of the work.

The attached sheets are not really full product reviews. They are written for fliers familiar with the Eagle Tree Guardian. The basic assumption is how the subject device compares to a Guardian for the line-of-sight fixed wing sport flying for which the Guardian was designed. Only features relevant to that application are included. The Vector, for example has many FPV and multirotor features that have no counterpart in a Guardian or this type of flying so these are not covered.

It's easy to get excellent self leveling with a Guardian without the detailed understanding described in this post. This is for people who are having problems, seeing things they don’t understand, having trouble achieving a specific result, or are just terminally curious. If none of these apply, please feel free to stop here and just follow the procedures in the New User’s Guide.

There is a lot of confusion among new users and even experienced users about how 2D manages flight. We know it does self-leveling when the sticks are centered but the behavior when sticks are moved is often misunderstood. To simplify, only bank angle will be considered in the rest of this discussion, pitch works the same way but bank angle is what people usually ask about. 2D doesn’t really manage yaw at all. If heading-hold is active it uses the ailerons to bank the plane onto the target heading. With no heading-hold it just levels. The rudder is inactive except for auto-turn-coordination if selected and the always present rate reaction to turbulence.

Concept:
Responding to a query, experienced users typically describe 2D something like this; “The stick controls the bank angle as a percentage of the max angle set in the software. Full stick means 100% of the 60░ max angle (default value).” In practice, however, there is more to it. The Guardian manages the bank angle to a “target” value based on three factors as follows.

1) Software “...Continue Reading

The attached PDF contains an illustrated description of some common encoding methods used in the hobby. It probably has more detail than most people need but you may find it interesting if you enjoy knowing how things work.

Some technical background is required to follow the descriptions. If you know that a millisecond (ms) is 1000 microseconds (Ás), that analog refers to continuously variable data like a speedometer with a needle while digital refers to discreet values like a speedometer with digits, and that digital data is represented in binary, then you probably know enough to get something out of this.

Attached is an updated version of the Guardian New User's Guide. This version has been updated to include the features added with the Eagle Tree software release 10.63 and firmware 1.24 and later. Also included are a few new tips that have surfaced since V1 was published over a year ago. (How time flies!)

For new users with software 10.52 and earlier, please consider upgrading. 10.52 has been discontinued. The current firmware is 10.65 which is the same as 10.63. If you choose not to upgrade, follow the original New User's Guide below. The main features added in 10.63 are bulleted here with more detail in this link: https://www.rcgroups.com/forums/show...2&postcount=12
  • Modes may be assigned to each position of the mode switch, with or without heading hold.
  • A provision was added for setting the level in flight and buttons for tweaking the level in the user interface.
  • A button was added to re-zero the gyros.
  • The 3D "center stick" zone was adjusted to make fine control movements smoother.
I hope this document will ease the transition into Guardian flying for many new users, and maybe encourage some existing users to move to the newer software/firmware. It really is worth making the change.

Special thanks to the following contributors and all those who offered their thoughts and suggestions in the RC-Groups Guardian thread and, of course, Eagle Tree for making such a fine product.

The attached pdf is a Guide for new users of the Eagle Tree Guardian 2D/3D.

The manual is loaded with information but it seems to be hard for first time users to put the needed pieces together to complete their installation. This guide is written primarily as a how-to. It is organized in a way that should make it easy to follow at different stages and includes some things that have been learned along the way in this forum, including some suggestions for various options and FAQs as an appendix.

I'm hoping it will be useful to newcomers.
