Circuit Avionics radio & autopilot panels

I haven't seen much coverage of these panels, which are all-metal construction and very good quality. They come with default profiles for the popular sims and are completely user-programmable. They are Arduino-based and need MobiFlight (free) to operate and to customise. The panels have been around for a year or more, I think originally as 'CircuitXL', now 'Circuit Avionics'. You can see my reviews below, and there are some more videos on my YT channel showing them in use.
