Programming ETHOS for the Archer SR Receivers for a conventional plane

I'll be covering how to setup the radio side of setting up the SR series receivers here. I'll go over receiver setup in a separate post. I'll also address Delta and V-Tail mixing another time.

First off, a couple things to cover on the receiver side because they significantly impact how you are going to program the radio.

1. Mixing. The SR series do internal delta and v-tail mixing. They DO NOT mix dual channel ailerons or dual channel elevators, although they can support both functions. You need to program delta and v-tail setups as conventional 4ch models on the radio, but dual-channel ailerons and elevators must be programmed at the radio.

2. USE QUICK MODE. the Archer SR series default to Quick Mode. Quick Mode doesn't support Hover Mode or Knife-Edge Mode. You probably don't need Hover Mode and Knife Edge mode only does one orientation and it's useless as a result. Plus the mode switching logic for these is nutty and requires a lot of in depth switchology to get usable switch setups from the crazy bad mode table. I'll only address Quick Mode in this post.

This post is going to cover how I program a standard aircraft with an Archer SR receiver. The dual elevators logic will be the same as dual ailerons.

First off we are going to create a new Model, and set it up as a standard 4 channel aircraft. Select 2 ailerons if you have/want dual channel ailerons.

The second step is to ensure the channels are mapped properly. If your default Channel Mapping is not AETR, you will need to remap the 4 basic channels

Make sure the channels are mapped as follows, by going to the Model->Mixer page and editing each mix and changing the Output channels for each mix if they don't match the following.

Ailerons->Ch1
Elevator->Ch2
Throttle->Ch3
Rudder ->Ch4

*Note if you are doing dual-channel ailerons, the right aileron must be on Ch5. Right Elevator must be on Ch6 if doing dual-channel elevators. These channels are hard coded at the receiver for stabilization.

How I do this is as follows. Note I have traditionally used TAER (JR/Spektrum) mapping as my default.

So I do this.

Edit Elevators mix. 
Set output channel from Ch3 to Ch7. Swap configs, accept channel name change. This clears Ch3 to be re-assigned without losing a channel name.
Edit Throttle Mix. 
Set output channel from Ch1 to Ch3. Swap configs, accept channel name change.
Edit Ailerons Mix.
Set output channel from Ch2 to Ch1. Swap configs, accept channel name change.
Edit Elevators mix. 
Set output channel from Ch7 to Ch2. Swap configs, accept channel name change.


Next, edit the Throttle mix, enable Throttle Cut, set the active condition to your preferred 'throttle disabled' setup, I use SFup on the X20. This is important later.

Now back out to the Mixer page

Hit the + to add a mix, select Free Mix, select Last Position
Change the name to Gain
Set the Source to Pot1 (or your preferred analog gain input)
Set the offset to 50%
Set the Weight Up to 50%
Set the Weight Down to 50%
Set the output Channel to Ch9, accept the name change offered

Now back out to the Mixer page

Hit the + to add a mix, select Free Mix, select Last Position
Change the name to Stab Mode
Set the Source to SB, or your preferred 3-position switch to control Stabilizer Modes
Set the output Channel to Ch10, accept the name change offered

Now back out to the Mixer page

Hit the + to add a mix, select Free Mix, select Last Position
Change the name to Panic
Set the Source to SH (or your preferred momentary for emergency self-level)
Set the Active Condition to SFdown, or the opposite position of the switch used for throttle hold (ie this mix will only be active if the throttle is active)
Set the output Channel to Ch12, accept the name change offered

Now back out to the Mixer page

Hit the + to add a mix, select Free Mix, select Last Position
Change the name to Self-Check
Set the Source to SA (or your preferred and otherwise unused 3-pos switch for self-check. this MUST be a 3-pos)
Set the Active Condition to SFup, the same condition Throttle Hold is active in (this will only be active if the throttle is disabled, to prevent self-check in the air)
Set the output Channel to Ch12, decline the name change if offered.

Now go to System->Hardware->Switches Settings and set the Switch middle detect delay to 0ms or Self-Check won't work.

For flaps, be sure to select your flaps configuration when creating the new model. Note that if your flaps are going to be on ch5 and/or 6, there is receiver configuration required,
