Support/FAQ for Pro templates

This page is for support of the templates on Ethos Hangar.

Where can I get the latest version of Ethos? And how do I flash it?

To download and flash the latest version of Ethos, install the Ethos Suite application. This is available from the Ethos GitHub site. Ethos Suite handles everything, from determining the firmware on your tx, to downloading and flashing the latest firmware and sound files. A USB cable will be required to connect the tx to your computer.

Will the templates work on my X18?

The Pro templates are built for the X20 however they should load fine on other transmitters such as the X18. There may be one or two changes needed if the target transmitter lacks certain controls. The setup guide explains how to reassign those controls. If you still have issues, please contact me.

How do I change the channel order?

There are two ways of changing the order of the servo channels.

Method 1 - remapping the rx pins

If you have an Archer receiver, or an RX- or G-RX-series receiver with the latest ACCESS firmware, then you can remap the receiver pins. This can be done 'over the air' from your Ethos transmitter.

First, register and bind the receiver. Then in the RF menu of your transmitter, open the RX Settings menu. There you'll see the pin mapping, which you can alter to suit.

Channel to rx-pin mapping (ACCESS only).

Method 2 - swapping channel outputs

The second way is to change the channel order directly, in the mixers menu. But beware, Ethos does not make it easy - you have to swap and reassign outputs, one mixer at a time.

To change a pair of channels,

  1. Open the mixer editor. Select the new output channel, choosing 'yes' when prompted to swap with the previous one. This swaps the name, min, max, subtrim, curve, etc. of the two outputs, as well as changing their assignments.
  2. For the remaining mixes for that channel, reassign (don't swap) the outputs. Follow the same process as above, except choose 'no' when prompted to swap.

The above procedure ensures that the internal data of the outputs are swapped only once. If you swap twice by mistake, the outputs will end up unchanged - the solution is to swap a third time!

Typically it'll be necessary to swap between two or three pairs of channels in order to achieve the required order. To avoid confusion, it's worth planning the swaps in advance. And remember to clone yourself a backup beforehand.

I can't see the template in the Model Select menu

Make sure you have at least the minimum Ethos version required for the template. The minimum is shown on the template page.

If the template is still not visible, it may be that there are special characters in .bin file name (this was the case with early versions of the templates). Rename the .bin file, changing upper case characters to lower case, and stripping out any non-alphanumeric characters. Then restart the transmitter.

How should I organise my models?

Use the 'custom folders' feature to organise your models (introduced in Ethos 1.1). For example, templates might go into a 'Templates' folder, unflown models would go in a 'Testing' folder, and so on.

Ethos also associates a model type with each setup, this being 'airplane', 'glider', 'heli', 'multi' or 'other'. The model type should not be changed, as it determines the mixers available for programming.


If you have a query, I can be contacted here. Please include as much detail as possible including: template name and version, Ethos version, transmitter, and the steps to reproduce the issue.
