Hi James,
the design is based on an idea from Menno (Mav2Hott) and I only added some DC/DC's (5V for powering the ESC's and LED's; 12V for video transmitters (since I want to use it in an FPV quad) and a LLC for connecting to a Spektrum TM1000 telemetry transmitter).
Once I confirmed the board working it will be shared on OshPark and I will also upload the schematics and the BOM to my CamCruiser build log (viewtopic.php?f=38&t=2920).
Rgds
