I found this and thought I’d share it. Another controller option if you’ve got $100 and a stout heart I do not necessarily endorse this controller, but it claims to come with a receiver, so it might be a feasible choice. There also seem to be some promising inputs ready for hackerin’ !
@lowGuido maybe you can add this to the pile of misfit controllers you’ve tried?
