This is a TBS Discovery & NAZA Lite build using the Turnigy 9XR. I'm doing this configuration for Solider53Flyer. He wanted to use the Turnigy 9XR 3 position switch so I've been figuring out how to do it. From what I understand the 9XR uses a derivative of the er9x firmware. I wanted to get familiar with er9x because I'm about to mod my 9X with the SmartieParts board and an er9x firmware load. So far I've been impressed with how robust the firmware is....after I've learned how to use it. If you have any suggestions for improving this configuration then I'm all ears. Thanks for watching!
