I’m closing in on you @Rodread. I just figured out how to send accelerometer data down to my RC transmitter, and from there I can control it quite simply with a Lua script… 
No soldering, no C++
There seems to be some problems we have in common: we want the electronics to align with the kite. For that we need to maintain spacing in the bridles front/aft or left/right. I also think its a good idea to support «pitch» of the controller «pod» with a longish rod… still working on the details
