The DiY R/C community has been doing some fabulous things with the low cost Turnigy/FlySky 9X R/C transmitter. They continue to make improvements and add useful features. It did not take long for a talented 9X developer to add a sophisticated voice (speech) feature. So of course I had to jump in and make mine talk too.

The voice feature is based on a very low cost MP3 sound module from China. The speech segments are stored on a SD memory card. All the details to the 9X voice mod are published here:
