Otherwise it will be truncated to -100%.+100%. Extended limits supported - A channel range of -125%.+125% will be transmitted.Channel ranges - A radio output of -100%.0%.+100% will match on the selected protocol -100%,0%,+100%.The module will take whatever input channel order you have choosen and will rearrange them to match the output channel order required by the selected protocol. You can change this in the compilation settings or by using a precompiled firmware. Channel Order - The channel order assumed in all the documentation is AETR.The Deviation project (on which this project was based) have a useful list of models and protocols here. If you want to see examples of model configurations see the Models page. Here are detailed descriptions of every supported protocols (sorted by RF modules) as well as the available options for each protocol.
