The Turnigy 9XR Pro has been released by HobbyKing. I've been beta testing it, and it seems like a pretty good radio. Here's a couple of pages of information I put together on it, including a video tutorial done in cooperation with the development team.
It's based on the much-admiredSky9x board which has been discussed here before. I'm excited to see another er9x based radio on the market. It's fully open sourced, ARM Cortex M3 based, and has all the nifty features you would expect. It has several open connection sets on the board, and was designed by skynorth to be open to hardware hacking as well as software hacking.
It's interesting to see how much open source development is moving to ARM.
