What drives the design of the steering yolk? I have seen many examples in aircraft over the years from the '8' to the 'W' and the 'U'.
I wonder if the design is largely 'design' or is it intended to affect the way in which the pilot approaches the handling of the particular aircraft? Perhaps the most interesting is the inverted 'W' in Conc. It resembles the 'ape hangar' handlebars of 1970's Harleys (a coincidence?

) As I read about the special handling characteristics of this machine, I wondered if the design had more than 'futuristic look' about it?
When you convert to a new machine, how does the new yolk affect that? Side-stickers should not set out to upset their yolking colleagues.
