Devo 7E is very limited by the amount of code memory it has. Many of additions, like advanced telemetry just can't be implemented in the boundaries of this small memory. Devo 7E is gradually dropping more and more features supported by higher models, which is a shame, because it's a lightweight and small TX with form factor still unmatched by other manufacturers. There is a mod - actually heart transplant which makes Devo 7E usable again, but it's not easy - it's an MCU replacement. Nobody wants it to die, but it seems inevitable.
