3- I use a length of 6-32 threaded rod and fender washers slipped through the counterbalance gap at the top of the rudder/vertical to hold the rudder at neutral (and also the elevators/horizontal).
4- In doing all this, my lengths are longer than expected- 3.1" & 3.5" hole to hole.
5- As mentioned, the actual lengths are not that critical, but need to make sure the rudder pedals don’t hit the firewall at full travel. I am only repeating this because you also need to consider include brake petals as well.
6- Going back to point 4, although I am happy with the rigging, one issue I had given the length of the links, the swedged end of the cable actually snags on the first guide hole. Still working a solution for this.
Are you building an RV-12? That is what this conversation was about ( the 12 is a little bit different from the others.
