OK, I finally (nearly) finished the project I wanted the Weatronic API for: a Guillows C172 conversion with GPS telemetry. (My build thread is http://www.rcuniverse.com/forum/begi...telemetry.html )

I have a u-blox NEO 7M GPS that gives me updates at 10 Hz which I am parsing with an Arduino. I have a spare serial port and I2C available and am ready to send GPS position, ground speed, and vertical speed to the SCU port of my Smart 8 receiver... All that I am missing is the API, i.e. the data format and protocol that the SCU port is expecting.

Is there any hope that Weatronic will make that available? Has somebody reverse engineered the SCU port? (I assume it is a serial port) Has somebody checked what data the Weatronic GPS spits out?
(Is it maybe just a plain NMEA data stream?)

Anyways, let me repeat my plea: Weatronic, please opensource your telemetry API. There is a ginormous market of folks like myself and the multirotor community ready to spend some money on a realiable two way receiver setup. Just think about all those FPV racers that would certainly put very good use to your Tiny 5... 12 cannel PPM and telemetry in such a tiny package... perfect.
