I used to think that I knew how I was going to connect the cables on system that has adjustable rudder pedals and side-by-side seating. Then I ran into some guys doing something else. So, in the interests of not re-inventing the wheel, how do you hook the two sides together? My rudder pedals move slide fore and aft, and have S tubes for the cables to slide in during adjustments, while the cables are anchored to the firewall.
Design options:
Two complete cable sets from firewall to rudder bellcranks. This means a lot of cable, fairleads/pulleys, and perhaps fuss to get them all tensioned and operating together;
One complete cable set with two pulleys to offset them to near the centerline, then a second set with offset tehm to the first set, and then use cable clamps to hook them to the first set;
Third idea is the one that got me thinking. They have a T shaped bellcrank arrangement behind each seat with the rudder cables from that side terminated on the sides, a link between the T-shaped bellcrank on each side, and then one bellcrank has cables to the rudder.
The first is rock simple, and can work, but geez the amount of cable and parts and opportunities for cable slack. Just does not seem like it would feel good... The second gets everything on the centerline tunnel I am planning, and only takes four pulleys, but somehow makes me a little nervos about having all four pedals working together. The last one should feel really solid, be great for dual instruction, but it means heavier and bulkier assemblies, which I would like to avoid.
So, what is actually used in this sort of thing, and how well does it work?
Looking forward to lots of thoughts on this...
