It’s taken us a while, but the totally new 2015 Edition of the Er9x Manual is now available. This is a complete overhaul of the documentation that not only reflects important improvements in the firmware, but provides much fuller explanations of the features and many detailed programming examples. It’s a comprehensive manual that covers every option and command.
The manual will be of assistance to anyone who wants to get the most out of a 9x or 9XR transmitter equipped with genuine Er9x firmware. Note that the manual does not cover the stock firmware provided with the 9x transmitter, or the modified version of Er9x that is included with the 9XR. To get maximum benefit, we recommend upgrading your firmware to the latest version of Er9x.
The manual also has a lot to offer to people using Ersky9x firmware in a 9XR Pro or 9x with a Sky board, as the two firmwares are now very close in their structure and capabilities.
The credit for the major improvements in recent versions of the firmware goes entirely to Mike Blandford, who has been fully responsible for Er9x since 2012. Mike, of course, built on the work of Erazz and other pioneers of open source RC firmware.
We hope the new manual will help modellers understand and apply this amazingly powerful and flexible software for years to come.
