ELRS telemetry can cause confusion for flyers migrating from other RC equipment where for example RSSI is a percentage and a positive number. These 2 videos are useful guides to the differences in elr...

I thought I would write something about flashing firmware that everyone using elrs should know, and likely knows already, just in case someone doesn`t. I am an elrs believer, after 12 months I rema...
