The current version of the silent_runner control code runs on an Arduino pro mini and is available on Github:
This small piece of software is written in the Arduino IDE and enables controlling of the inverted Y fins. It also provides the opportunity to add more fancy Arduino controlled features. If you have a good programmable RC-Sender that allows an inverted Y fin layout, you are fine without the Arduino. The code is intensively commented for easy understanding and is provided as a basic sketch for working with RC equipment.
