My Taranis Q X7 Access only supports CH16. I updated it to the latest firmware with OPEN TX, CH8 still not available as an option. I then checked on the official website, Taranis Q X7 Access doesn’t support CH8. Gladly Tiny Hawk S does, it is set to CH8 by default but can be changed using the Betaflight Configurator based on this video:
Betaflight Configurator: https://github.com/betaflight/betaflight-configurator/releases/tag/10.5.1
Tiny Hawk failed to connect with Betaflight. I tried to install all the drivers, but didn’t work out. Betaflight was able to detect and connect to the port, but “No configuration received within 10 seconds, communication failed“ and then the connection closed.
