I watched the same, skywagon university, a great YouTube channel.
My baby Beechcraft 23 has the same system. It is just a spring inter connect between the rudder and aileron. To be honest I don't think about it while flying the mighty Musketeer. It is easy to over power if you want full rudder without any aileron input.
The seats in the Musketeer have that same arm chair feel as the debonair very comfortable at a much lower speed, love it.
