Electronic design files:

The sensor station uses two MOSFETS as voltage convertor for the DATA connection. Although some people feed the I2C lines with 5Volt I think that is not a good idea. The Optima 7/9 expects 3.3V signal.
(@Hitec, does 5V (eventually) harm the Optima's?).
Here a some measurement results of the voltage convertor and the data signals.

Main (basic) support is through excellent rcgroups forum:
