I'm doing something completely different. I'm currently in the process of hacking my TX to convert it to a fully custom, C-programmable*, computer radio.
Just soldered on connectors on the radio board last night so I can insert a small microcontroller and intercept/modify the PPM signal. In the process of drafting a circuit board.
*note: Those of you who don't write software won't understand it but those of you who write software will understand why I want this
