Here's a cool project to open source the telemetry data stream that the Aurora 9 RC gear uses:
Among others, one thing that makes the 2.4GHz Aurora 9 so great is the big LCD in combination with the full telemetry features of the Optima 7/9 receivers. These receivers contain a so-called data port that connects to Hitec’s sensor station. Sensor stations come in 2 flavors: a nitro version for gas and glow powered planes and a blue version for electric powered aircrafts.
But … Hitec’s sensor stations are not so versatile as they should be, therefore I developed one by myself. It works so great that I decided to share my design and introduce a DIY kit. Also great is that all software and hardware is open source. Build one by yourself or buy a DIY kit containing all necessary components and a professionally manufactured circuit board.

This is an excellent and well done hack for Hitec Aurora 9 owners.
When looking at telemetry systems it's possible to find yourself with triplicate systems on board for Tx/Rx telemetry, FPV, and OSD. Example: Three (3) GPS devices feeding data to three isolated systems.
The most important take away from this project for me was that the Optima 9 Receiver takes I2C as input (at 3.3V).
APM can communicate using I2C.
There would be no need to buy the Hitec telemetry gear if APM had a module to stream output (from its sensors) via I2C to the Optima 9 data port (which would then be transmitted to the Aurora 9 Receiver).
